What is a Poke Cake?

A poke cake is a delightful and ingenious dessert known for its exceptional moistness, tender crumb, and deeply infused flavors. The concept is wonderfully simple yet highly effective: a freshly baked cake, typically still warm from the oven, is “poked” with numerous holes across its surface. This is usually done using the handle of a wooden spoon, a sturdy straw, or a wooden skewer. These created channels are then generously filled with a liquid or semi-liquid mixture. Common fillings include Jello, instant pudding, sweetened condensed milk, or even fruit purees.

As the chosen liquid seeps into the cake through the poked holes, it adds an incredible boost of moisture and permeates the cake with additional flavor, transforming a standard cake into something truly extraordinary. The gelatinous nature of Jello, in particular, allows it to set within the cake, creating pockets of vibrant color and concentrated flavor, while ensuring the cake remains wonderfully soft and tender. The primary advantage of a poke cake is its ability to prevent dryness, a common complaint with many traditional cakes. The infusion keeps the cake moist and flavorful for several days, making it an excellent make-ahead dessert for any occasion. This method also opens up a world of creative flavor combinations, with the filling perfectly complementing or delightfully contrasting the cake base. For our Lemon Jello Poke Cake, the lemon Jello not only enhances the citrus notes but also contributes to the cake’s vibrant yellow color and irresistible, tangy sweetness.

How to Make Lemon Jello Poke Cake

Crafting this Lemon Jello Poke Cake is an enjoyable and straightforward process. This recipe cleverly uses a quality boxed cake mix as a starting point, saving you precious time without compromising on the incredible homemade taste. We’ll elevate the basic mix with fresh lemon additions, then infuse it with a bright and tangy lemon Jello filling, and finally top it off with a dreamy, light, and homemade lemon pudding frosting. Each component works in harmony to create a symphony of citrusy goodness and unparalleled moisture. The entire process is designed to be accessible, ensuring a perfect bake even for those new to cake decorating, with delicious results every single time.

Essential Ingredients for Your Lemon Poke Cake

Before you begin your baking adventure, gathering all your ingredients is a crucial step for a smooth and enjoyable process. Here’s a detailed look at what you’ll need and why each component plays a vital role in creating this magnificent cake:

For the Cake:

  • 15 oz. box lemon cake mix: This forms the delicious foundation of our cake. While a homemade lemon cake can certainly be used, a quality boxed mix offers exceptional convenience and consistent, reliable results. It provides the essential structure, sweetness, and a foundational lemon flavor that we will further enhance.
  • Ingredients called for on box (typically eggs, oil, water): These standard additions bring the boxed mix to life.
    • Eggs: Crucial for binding the batter together, adding richness, and helping the cake achieve a beautiful rise and a delightfully tender texture.
    • Oil: Contributes significantly to the cake’s moistness and provides a luxurious mouthfeel. Using a neutral-flavored vegetable oil ensures the delicate lemon flavor shines through without interference.
    • Water: Activates the dry ingredients in the cake mix and ensures the batter has the correct, pourable consistency, which is vital for an even bake.
  • 1 lemon, juiced and zested: This is where we truly elevate the boxed mix from ordinary to extraordinary.
    • Zest: Packed with potent aromatic oils, the finely grated zest delivers an intense, natural lemon aroma and a powerful, vibrant flavor without adding extra liquid, ensuring a truly vibrant citrus profile.
    • Juice: Adds a bright, fresh acidity that masterfully balances the sweetness of the cake, enhancing and brightening the overall lemon taste. Freshly squeezed juice is always recommended for maximum impact and a pure, clean flavor.

For the Filling:

  • 3 oz. box lemon Jello: This is the star of our poke cake. It not only provides a vivid, enticing lemon flavor and color but its gelatinous nature allows it to soak deeply into the cake, creating incredible moisture, a delightful tang, and a unique, refreshing texture.
  • ½ cup hot water: Essential for thoroughly dissolving the gelatin powder. Whisking it vigorously in hot water ensures a smooth, lump-free filling that can easily penetrate the cake’s pores.
  • ½ cup cold water: Added to quickly cool the Jello mixture to the ideal temperature. This prevents the warm Jello from ‘cooking’ the cake further or damaging its delicate structure, ensuring it sets properly once poured.

For the Lemon Pudding Frosting:

  • 2 cups heavy cream: The lush base for our light, airy, and incredibly fluffy frosting. When whipped to perfection, it creates a rich, creamy, and wonderfully voluminous topping that provides a perfect contrast to the dense, moist cake below.
  • ¼ cup powdered sugar: Sweetens the frosting to perfection and, importantly, helps stabilize the whipped cream, giving it a better structure and preventing it from deflating quickly, ensuring a beautiful presentation.
  • ¼ cup lemon pudding or Jello mix (dry, instant): This is a fantastic culinary trick! The dry mix not only boosts the lemon flavor significantly but also acts as a thickening agent, providing additional stability to the whipped cream. This results in a firmer, more delightful topping that holds its shape beautifully. Ensure you are using an instant pudding mix, not one that requires cooking.

Step-by-Step Guide to Baking the Perfect Lemon Jello Poke Cake

Crafting this lemon Jello poke cake is an incredibly straightforward and rewarding process. While simple, paying close attention to a few key details will ensure your cake turns out consistently perfect, unbelievably moist, and bursting with zesty flavor every single time!

Our essential lemon ingredients, ready for baking this delightful dessert.

1. Prepare Your Baking Pan and Oven

Begin by preheating your oven to the exact temperature required. If you’re using a dark non-stick baking pan, set your oven to 325°F (160°C). For a lighter-colored metal or glass pan, which tends to retain and distribute heat differently, preheat to 350°F (175°C). This slight temperature adjustment is crucial for an even bake and to prevent the cake from over-browning. Next, generously grease a standard 9×13-inch baking pan with non-stick cooking spray, or alternatively, butter and lightly flour it, to ensure the cake releases easily after baking. Set the prepared pan aside, ready for your beautifully scented batter.

2. Mix and Bake the Lemon Cake Base

Carefully follow the specific instructions provided on your boxed lemon cake mix for preparing the batter. This process typically involves combining the dry mix with eggs, oil, and water in a large mixing bowl. Once the basic batter is mixed and smooth, it’s time to infuse it with even more fresh lemon flavor. Gently fold in the freshly squeezed juice and the finely grated zest from one whole lemon. Be mindful not to overmix the batter once the wet and dry ingredients are combined, as this can lead to a tough cake; mix just until no streaks of flour remain. Pour the enriched batter evenly into your previously prepared 9×13-inch baking pan. Bake for approximately 30-35 minutes if using a non-stick pan, or 25-30 minutes for a glass pan. To check for doneness, insert a wooden toothpick into the center of the cake; it should come out clean or with a few moist crumbs attached.

3. Poke Holes for Optimal Flavor Infusion

Once your cake is out of the oven, allow it to cool slightly for about 10-15 minutes, but ensure it is still warm. This warmth is absolutely key for optimal absorption of the Jello mixture. Now, it’s time to create the channels for our delicious Jello filling. Using the back of a wooden spoon handle, a thick straw, or a wooden skewer, systematically poke holes evenly across the entire top surface of the cake. Aim for holes that are deep enough to reach about halfway to two-thirds down into the cake, but be careful not to poke all the way through to the bottom, which could make the cake soggy. Space them approximately an inch apart. This meticulous poking ensures the lemon Jello penetrates deeply and evenly, creating delightful pockets of intense flavor and moisture throughout every single slice of cake.

4. Add the Refreshing Jello Filling

In a medium-sized heatproof bowl, add the lemon Jello mix. Pour in ½ cup of boiling hot water and whisk vigorously for at least 2 minutes, or until the Jello powder is completely dissolved and no granules remain. Then, add ½ cup of cold water to quickly cool the mixture down to a lukewarm temperature. This step is crucial to prevent the hot Jello from “cooking” the cake further or making it gummy. Once cooled slightly, carefully and slowly pour the lemon Jello mixture over the entire poked surface of the cake. Take your time, ensuring the liquid gracefully seeps into all the holes. Place the cake into the refrigerator to chill and allow the Jello to set completely, which will take a minimum of 2-4 hours, or ideally, overnight. This extended chilling period is absolutely crucial for achieving the perfect moist texture and fully infusing the cake with its vibrant lemon flavor.

5. Prepare the Light and Fluffy Lemon Pudding Frosting

Once your cake is perfectly chilled and the Jello has firmly set (after its minimum 2-hour stay in the fridge), it’s time to prepare the crowning glory: the luscious lemon pudding frosting. In a large mixing bowl, or the bowl of a stand mixer fitted with a whisk attachment, combine the very cold heavy cream, powdered sugar, and the dry instant lemon pudding or Jello mix. Beat on medium-high speed until the mixture transforms into stiff, light, and wonderfully fluffy peaks. It’s important to watch closely and stop immediately as stiff peaks form, as heavy cream can quickly over-whip and turn grainy. The instant pudding mix not only adds an extra burst of concentrated lemon flavor but also acts as a fantastic stabilizer for the whipped cream, ensuring your frosting holds its beautiful shape and texture.

6. Frost and Serve Your Masterpiece

With the cake impeccably chilled and the frosting prepared to perfection, gently spread the luscious lemon pudding frosting evenly over the entire top surface of the cake. An offset spatula works wonderfully for achieving a smooth, professional finish. For an extra touch of elegance and to beautifully reinforce the lemon theme, consider garnishing with delicate lemon zest curls, thin slices of fresh lemon, or even a sprinkle of chopped candied lemon peel. Your magnificent Lemon Jello Poke Cake is now ready to be enjoyed! Serve immediately for the freshest experience, allowing guests to savor its cool, creamy, and zesty delights. Alternatively, store it covered tightly in the refrigerator until ready to slice and share. The flavors will continue to meld and deepen with time, often making it even more delicious the next day.

Expert Tips and Tricks For a Flawless Lemon Jello Poke Cake

Achieving the perfect Lemon Jello Poke Cake involves a few simple yet crucial secrets. Follow these expert tips to ensure your cake is always incredibly moist, intensely flavorful, and a true showstopper at any gathering:

Cake Baking Tips:

  • Mindful Mixing Prevents Density: It is paramount to avoid overmixing the cake batter at all costs. Overmixing develops the gluten too much, leading to a tough, dry, and dense cake. Mix just until the dry ingredients are fully incorporated and no streaks of flour remain, then stop. A soft, tender, and airy crumb is the ultimate goal.
  • Amplify Lemon Flavor with Extra Zest: For an even more profound and aromatic lemon taste, don’t hesitate to add a little extra fresh lemon zest to your cake batter beyond what’s called for. Zest contains the lemon’s essential oils, providing a powerful, natural citrus burst without altering the batter’s liquid consistency.
  • Fresh Lemon Juice Makes All the Difference: While bottled lemon juice is convenient, freshly squeezed lemon juice offers a brighter, more vibrant acidity and a pure, clean aroma that bottled alternatives simply cannot replicate. It truly elevates the cake’s fresh citrus profile and enhances its overall appeal.
  • Room Temperature Ingredients for Best Results: Ensure your eggs, water, and oil are at room temperature, as often specified by the cake mix instructions. This allows them to emulsify more effectively with the dry ingredients, creating a smoother, more uniform batter and a more evenly baked, tender cake.
  • Avoid the Pitfall of Overbaking: Overbaking is the arch-enemy of a moist cake. Start checking for doneness a few minutes before the recommended minimum baking time. A wooden toothpick inserted into the center should come out with moist crumbs, but not wet batter. Remove promptly from the oven to retain moisture.

Poking & Filling Perfection:

  • Poke While Still Warm: The absolute best time to poke holes is when the cake is still warm, ideally about 10-15 minutes after it comes out of the oven. The residual warmth helps the cake absorb the Jello mixture more effectively and thoroughly.
  • Choose Your Tool Wisely for Ideal Channels: A wooden spoon handle, a thick, sturdy straw, or a large, blunt wooden skewer creates ideal holes for the Jello to seep into. Avoid using a thin toothpick, as it might not create wide enough channels for thorough saturation, leading to uneven moisture.
  • Strategic Hole Placement for Evenness: Poke holes evenly across the entire surface of the cake, maintaining approximately 1-inch spacing between each hole. Aim for consistency to ensure every single slice receives an equal and delightful distribution of Jello.
  • Depth Matters for Optimal Absorption: Ensure the holes are deep enough to reach about halfway to two-thirds down into the cake. This allows for maximum moisture absorption and flavor infusion without compromising the cake’s structural integrity or creating a soggy bottom layer.
  • Pour Jello Slowly and with Patience: Patience is a virtue when adding the Jello mixture. Pour it slowly and steadily over the poked cake, allowing the liquid to fully absorb into each hole. You might find it beneficial to pour it in several passes, letting each layer soak in before adding more, to prevent run-off and ensure even distribution.
  • Preserve Edges, Avoid Soginess: Leave a small border (about half an inch to an inch) around the edges of the cake when poking holes and pouring Jello. This subtle strategy helps the cake hold its shape better and prevents the outer edges from becoming overly saturated and potentially soggy, maintaining a pleasant texture throughout.

Essential Chill Time Tips

  • Minimum Chill Time is Crucial: Allow the cake to chill thoroughly in the refrigerator for at least 2-4 hours after adding the Jello. This essential step allows the gelatin to set completely and ensures the vibrant flavors meld beautifully throughout the cake. For optimal results, an overnight chill is highly recommended.
  • Achieve Cleaner Slices with Proper Chill: A fully chilled cake is significantly easier to slice cleanly. The set Jello reinforces the cake’s structure, preventing crumbling and creating neat, attractive slices that are a pleasure to serve and eat.
  • Airtight Storage is Paramount: Always cover the cake tightly with plastic wrap or aluminum foil during chilling. This vital step prevents the cake from absorbing unwanted odors from the refrigerator, keeps the surface from drying out, and maintains its exquisite moisture content.

Fluffy Frosting Wisdom

  • Cold Tools for Whipping Success: For the fluffiest and most stable whipped cream frosting, place your mixing bowl and whisk attachment (from your stand mixer or hand mixer) in the freezer for 10-15 minutes before you begin whipping. Cold tools dramatically help the heavy cream whip up faster and achieve a more stable, airy, and voluminous texture.
  • Whip to Stiff Peaks, and Stop Promptly: Beat the heavy cream until stiff peaks form. This means that when you lift the whisk, the peaks hold their shape firmly and stand upright. It is crucial to stop immediately at this point to avoid over-whipping, which can quickly turn your beautiful cream into a grainy, separated, and undesirable buttery consistency.
  • Gentle Folding for Airiness Preservation: Once the heavy cream is perfectly whipped, gently fold in the dry pudding mix. The pudding mix acts as both a flavor enhancer and a subtle thickening agent. Folding it in carefully preserves the light and airy texture of the whipped cream, ensuring your frosting remains wonderfully delicate.
  • Adjust Sweetness to Your Liking: If you prefer a less sweet frosting, you can slightly reduce the amount of powdered sugar. However, remember that powdered sugar also plays a role in stabilizing the whipped cream, so avoid reducing it too drastically.

Elegant Serving Suggestions

  • Garnish for Enhanced Visual Appeal: Elevate your cake’s presentation by topping it with delicate lemon slices, beautiful lemon zest curls, or even a sprinkle of finely chopped candied lemon peel. These garnishes not only add a professional touch but also visually reinforce the delightful lemon theme.
  • Serve Chilled for Optimal Flavor Experience: This cake truly shines when served cold. The refreshing cool temperature enhances the vibrant lemon flavor and provides a delightful contrast to the creamy texture of the frosting, making each bite incredibly invigorating.
  • Achieve Clean Slices with a Warm Knife: For perfectly neat and clean slices, a simple trick is to dip a sharp knife in hot water and wipe it dry between each cut. This technique helps the warm blade glide effortlessly through the cake and frosting without tearing or smudging.

Flavor Variations to Try

While the classic lemon combination in this poke cake is undeniably irresistible and a true crowd-pleaser, the inherent beauty of poke cakes lies in their incredible adaptability. Don’t be afraid to unleash your creativity and experiment with different flavors to perfectly suit your taste preferences, seasonal availability, or the specific occasion:

  • Berry Blast: For a delightful fruity twist, easily swap the lemon Jello for vibrant strawberry, sweet raspberry, or tangy cherry Jello. To amplify the experience, you can even gently fold in fresh berries into the frosting or scatter them as a colorful garnish for an extra burst of natural fruity goodness.
  • Lime Zing: If you’re seeking a slightly different but equally refreshing citrus experience, opt for zesty lime Jello. Enhance this by adding a bit of fresh lime zest and juice to both the cake mix and the frosting. This variation creates a vibrant, tangy dessert reminiscent of a classic key lime pie, perfect for summer.
  • Tropical Paradise: Transport your taste buds to a sun-drenched beach by considering tropical Jello flavors such as pineapple, orange, or even a mixed fruit blend. A subtle touch of coconut extract incorporated into the frosting could further enhance this exotic theme, creating a truly unique dessert.
  • Chocolate Decadence: While less conventional for poke cakes, you could certainly experiment with a chocolate cake mix as your base. After baking, poke it and fill it with creamy chocolate pudding or even a coffee-flavored Jello for an intriguing mocha-inspired treat that’s rich and sophisticated.
  • Richer Cream Cheese Frosting: If your palate leans towards a richer, tangier frosting, a classic cream cheese frosting would also pair absolutely deliciously with the bright lemon cake and its Jello-infused filling. This provides a delightful contrast in texture and flavor.
  • Adding Fresh Fruit for Texture: For an added layer of texture and natural sweetness, incorporate finely diced fresh fruit – such as ripe strawberries, plump blueberries, or sweet peaches – either into the Jello mixture before pouring, or gently fold them into the frosting just before spreading.

How To Store Jello Poke Cake

Proper storage is absolutely essential to maintain the exceptional freshness, delectable moisture, and vibrant flavor of your Lemon Jello Poke Cake. Given that this cake contains a gelatin filling and a delicate dairy-based frosting, refrigeration is not just recommended, but an absolute must.

  • Refrigeration is Imperative: Always store your frosted poke cake in the refrigerator. The Jello filling requires a cold environment to remain perfectly set and firm, and the whipped cream frosting will hold its light, airy texture best when kept thoroughly chilled.
  • Airtight Coverage is Key: To prevent the cake from drying out, absorbing any unwanted odors from the refrigerator, and to help the frosting maintain its beautiful integrity, wrap any leftover cake tightly with multiple layers of plastic wrap or place it securely in an airtight container.
  • Duration of Freshness: When stored correctly in the refrigerator, your frosted Lemon Jello Poke Cake will remain deliciously fresh and perfectly edible for two to three days. It’s worth noting that while the whipped topping might slightly deflate or lose a bit of its fresh structure after a couple of days, the underlying cake itself will still be wonderfully moist and the lemon flavor just as fantastic.
  • Garnish Removal Suggestion: If you’ve chosen to garnish your cake with thin slices of fresh lemon, it’s generally advisable to carefully remove them after initial serving or before storing the cake for an extended period. Fresh lemon slices can sometimes develop a bitter taste or lose their visual appeal after prolonged contact with the cake, and they may also potentially contribute to the cake spoiling slightly faster.

Frequently Asked Questions About Lemon Poke Cakes

What is a Poke Cake?

A poke cake is a unique and wonderfully moist baked cake. After baking, holes are strategically poked into its surface, typically using the handle of a wooden spoon or a skewer. These holes are then filled with a liquid or semi-liquid mixture, such as Jello, pudding, or sweetened condensed milk. This infusion deeply permeates the cake, enhancing its flavor, adding significant moisture, and creating a delightful, tender texture that stands out from traditional cakes.

Can I use a different flavor of Jello?

Absolutely! While lemon Jello perfectly complements the lemon cake for a unified citrus experience, poke cakes are incredibly versatile. You can easily swap in other Jello flavors like vibrant raspberry, sweet strawberry, or tangy lime for a fun and delicious twist. Each flavor will pair well with the foundational lemon cake, offering a slightly different profile while maintaining the characteristic moisture and tender texture.

Do I have to use boxed cake mix?

Not at all! A homemade lemon cake recipe will work beautifully as the base for this poke cake. However, using a high-quality boxed mix is a fantastic time-saver and still yields consistently moist and flavorful results, especially when enhanced with fresh lemon juice and zest as detailed in this recipe. It’s a great option for convenience without sacrificing taste.

How far in advance can I make this cake?

This cake is an excellent make-ahead dessert! You can prepare it 1–2 days in advance. In fact, many find that the flavors deepen and meld even more beautifully after a full day of chilling in the refrigerator, making it taste even better on the second day. Just ensure it’s tightly covered with plastic wrap or in an airtight container to retain its moisture and freshness.

Why is my cake soggy or mushy?

Cakes can become mushy or soggy due to several common issues:

  • Too Many Holes or Too Close: Poking an excessive number of holes or spacing them too closely together can cause the cake to break down and become overly saturated.
  • Not Cooling Enough: Pouring the Jello when the cake is still too hot can cause the cake’s structure to collapse or become mushy. Always allow the cake to cool slightly (to warm, not hot) before pouring the liquid Jello.
  • Excessive Jello: Using too much liquid Jello relative to the cake size can lead to oversaturation, making the cake waterlogged.
  • Insufficient Chill Time: Not allowing the cake to chill long enough (at least 2-4 hours) for the Jello to properly set within the cake’s pores can result in a soft, unset, and therefore mushy texture. Ensure it’s fully chilled before slicing.
Can I freeze Lemon Jello Poke Cake?

Yes, you can freeze the cake, but it’s highly recommended to do so without the delicate whipped topping. Once the cake has been baked, poked, filled with Jello, and has fully chilled and set, wrap it tightly in several layers of plastic wrap, followed by an outer layer of aluminum foil. Freeze for up to 2 months. When ready to serve, thaw the cake in the refrigerator overnight, then prepare and add the fresh whipped frosting just before serving for the best texture and taste.

How long does lemon poke cake last in the fridge?

When stored tightly covered in the refrigerator, this Lemon Jello Poke Cake will last for 3–4 days. While the whipped topping might slightly deflate or lose a bit of its fresh structure after a couple of days, the cake itself will remain wonderfully moist and the vibrant lemon flavor will continue to be delicious and refreshing.

Deliciously moist lemon cake infused with lemon Jello and topped with a light, creamy lemon pudding frosting!

Equipment

  • Stand Mixer (or Hand Mixer)
  • 9×13 inch Baking Pan
  • Wooden Spoon Handle or Skewer (for poking holes)
  • Large Mixing Bowls

Ingredients

For the Cake:

  • 1 (15 oz.) box Lemon cake mix, plus ingredients called for on back of box
  • 1 lemon, juiced and zested

For the Filling:

  • 1 (3 oz.) box lemon Jello
  • ½ cup hot water
  • ½ cup cold water

For the Lemon Pudding Frosting:

  • 2 cups heavy cream
  • ¼ cup powdered sugar
  • ¼ cup lemon pudding or Jello mix (dry, instant)

Instructions

  1. Preheat the oven to 325°F (160°C) for a dark non-stick pan or 350°F (175°C) for a glass pan. Grease a 9×13-inch pan with non-stick spray and set aside.
  2. Prepare the cake batter according to the box directions, then fold in the fresh juice and zest from the lemon for an enhanced flavor.
  3. Pour the batter into the prepared baking pan and bake for 30 to 35 minutes (non-stick) or 25 to 30 minutes (glass), or until a toothpick inserted into the center comes out clean.
  4. Allow the cake to cool slightly for about 10-15 minutes. Then, use the back of a spoon, a straw, or a wooden skewer to poke holes evenly all over the top of the cake, ensuring they go about halfway down.
  5. In a medium bowl, add the lemon Jello mix and whisk in the hot water until fully dissolved. Stir in the cold water. Carefully and slowly pour the mixture over the top of the poked cake, making sure it seeps into all the holes.
  6. Place the cake in the refrigerator to set for at least 2 hours. Overnight chilling is recommended for optimal results.
  7. Once the cake is set, combine the heavy cream, powdered sugar, and dry lemon pudding/Jello mix in a large bowl or stand mixer with a whisk attachment. Beat on medium-high speed until the frosting is stiff, light, and fluffy.
  8. Spread the frosting evenly over the top of the chilled cake. Garnish with lemon zest or slices if desired. Enjoy immediately or store covered in the refrigerator.

Notes

  1. Adding fresh lemon juice and zest significantly boosts the tartness and intensity of the lemon flavor. While optional, omitting them will result in a sweeter, less vibrant lemon cake.
  2. The original poke cake recipes often featured a frosting made with whipped topping (like Cool Whip). Our lemon pudding frosting offers a richer, more homemade taste while retaining a light and airy texture.
  3. Baking times can vary based on your specific oven and the type of cake mix used. Always refer to your cake mix box for the most accurate guidelines and check for doneness regularly.
  4. Patience is key: the chilling time for the Jello to set is crucial and cannot be rushed. Allow sufficient time for the best results to achieve the perfect moist texture.
  5. Leftovers should be stored tightly covered in the refrigerator and will stay fresh for 2 to 3 days.
