Easy Banana Snack Cake with Delightful Pudding Frosting
Discover the ultimate recipe for a single-layer banana snack cake, perfectly baked in a 9×9 inch square pan and topped with a luscious pudding frosting. This homemade delight is as quick to prepare as a cake mix banana pudding cake, yet boasts the rich, from-scratch flavor that only truly ripe bananas can provide. It’s the ideal treat for any occasion, offering a simple yet incredibly satisfying dessert experience.

This banana cake, crowned with a creamy instant pudding frosting, is remarkably simple to bake and consistently delivers a moist, tender crumb. It stands out as one of our favorite overripe banana recipes, perfect for a special breakfast treat or a delightful dessert after dinner. The natural sweetness and moisture from the ripe fruit ensure every bite is incredibly tender and flavorful, making it a guaranteed crowd-pleaser.
While sharing a similar moist texture to our Banana Bread Bundt Cake, this snack cake is designed for a smaller gathering. Its 9×9 inch square pan size yields a single, perfectly portioned layer, making it an excellent choice for a family of four to enjoy over a couple of days. Beyond its deliciousness, it’s a brilliant way to utilize those forgotten, browning bananas on your countertop, transforming them into a culinary triumph instead of letting them go to waste.
Achieving the perfect flavor and moisture in your banana cake begins with the right bananas. Forget throwing away those overly ripe, dark-skinned bananas – they are a baker’s best friend! A bit more effort in mashing them compared to a layered Banana Dump Cake, but the result is a cake bursting with natural sweetness and an irresistible aroma. The darker the bananas, the more their natural sugars have developed, leading to a sweeter, more intensely flavored cake. Aim for bananas that are heavily spotted or almost entirely brown for the most outstanding results.

Crafting Your Perfect Banana Snack Cake
While this recipe focuses on a simple, single-layer cake, the versatility of banana cake allows for many creative adaptations. We’ve even transformed this recipe into a Banana Upside Down Cake by adding a caramel layer and fruit slices to the bottom of a round pan, which flips to become a beautiful topping. When it comes to add-ins, the possibilities are endless! Feel free to customize your cake with anything from crunchy chopped walnuts, delightful mini chocolate chips, or sweet caramel bits. If you prefer, keep it plain and let the pure banana flavor shine through – it’s delicious either way.
The crowning glory of this snack cake is its simple yet heavenly pudding frosting. You have two fantastic options for the topping. The quickest method involves simply whisking together instant pudding mix and milk for a smooth, classic finish. However, for an extra layer of decadence and an irresistibly airy texture, fold in a tub of whipped topping to create our signature Cool Whip Pudding Frosting. The difference lies in the luxurious creaminess and thickness of the latter, delivering a bite of pure heaven. We encourage you to try both variations to discover your personal favorite!
For best baking results, always remember the fundamental technique of combining your dry ingredients in one large bowl and your wet ingredients in another. This ensures a consistent mixture before gently incorporating them into a light and fluffy batter. If you’re planning to include any delightful mix-ins like nuts or dried cranberries, fold them in gently at the very end to prevent them from sinking. This particular pudding cake distinguishes itself by having the pudding incorporated as a luscious topping rather than mixed directly into the batter, allowing its distinct flavor and texture to truly stand out.

Baking Your Banana Cake in a 9×9 Inch Pan
The 9×9 inch square pan is ideal for this single-layer banana snack cake, providing generous slices perfect for casual indulgence. Much like quick breads, such as our Banana Bread with Yellow Cake Mix, you have some flexibility with the pan size. If you desire a taller, narrower cake, a rectangular loaf pan (the larger variety) would work wonderfully. Regardless of your choice, we highly recommend lining your baking pan with parchment paper. This simple step makes it incredibly easy to lift the entire cake out once baked, allowing it to cool properly on a wire rack before you even think about frosting it. This prevents the cake from continuing to bake in the hot pan and ensures it remains wonderfully moist.
Should you be hosting a larger gathering or simply wish for a more impressive presentation, this recipe can easily be doubled to create a two-layer cake. Simply divide the batter between two 9×9 inch pans, or bake in a larger pan and carefully slice it horizontally. The addition of a rich cream cheese frosting, perhaps infused with a hint of banana flavor, between the layers and on top, transforms this humble snack cake into an elegant dessert. A multi-layered banana cake with a creamy filling is always a beloved hit with family and friends, offering both a beautiful visual and an unforgettable taste experience.

Frequently Asked Questions About Banana Cake
Can You Replace Eggs with Bananas to Make a Cake?
Yes, absolutely! A single ripe banana can effectively replace one egg in many cake recipes. This is an excellent option for those with dietary restrictions requiring an egg-free cake. Beyond dietary needs, using mashed banana as an egg substitute significantly boosts the cake’s moisture content, resulting in an incredibly tender crumb. Keep in mind that replacing all the eggs with bananas might yield a slightly denser cake than one made with eggs, but its unparalleled moistness more than makes up for it. Experiment to find your preferred balance!
How Brown Should Bananas Be to Make Banana Cake?
The ideal bananas for baking a truly exceptional banana cake are ripe to the point of being significantly brown, or even what some might consider overripe. Look for bananas with a deep yellow skin that is generously covered in brown spots or patches. Crucially, they should feel soft to the touch and be very easy to mash. This level of ripeness indicates maximum sugar development and a softer texture, which translates into a naturally sweeter, more flavorful, and incredibly moist cake. Don’t be afraid of very dark bananas; they’re packed with flavor!

Banana Snack Cake Recipe

This easy, single-layer banana cream cake, topped with smooth pudding frosting, is a quick and delightful dessert. Baked in a 9×9 inch pan, this moist ripe banana cake is perfect for any sweet craving.
Prep Time: 10 mins | Cook Time: 40 mins | Servings: 12
Equipment
- 1 9×9 inch pan
- 2 mixing bowls
Ingredients
For the Cake:
- 1 cup butter, unsalted, melted
- 2 cup brown sugar, packed
- 2 large eggs, at room temperature is best
- 1 tsp vanilla extract
- 2 cup all purpose flour
- 1/2 tsp baking powder
- 1/2 tsp salt
- 1 cup ripe bananas, mashed (should be browned)
For the Pudding Frosting:
- 1 box instant pudding mix, banana flavor
- 1 3/4 cup whole milk
Instructions
- Preheat your oven to 350°F (175°C). Prepare a 9×9-inch baking pan by lightly coating it with nonstick cooking spray and lining it with parchment paper, allowing some overhang for easy removal. In a large mixing bowl, combine the melted butter and brown sugar, mixing until they are well blended and smooth. Beat in the eggs one at a time, ensuring each is fully incorporated before adding the next. Finally, stir in the vanilla extract until just combined.
- In a separate medium-sized bowl, whisk together the dry ingredients: all-purpose flour, baking powder, and salt. Gradually add this dry mixture to your wet ingredients, mixing only until just combined. Be careful not to overmix, as this can lead to a dense cake. Gently fold in the mashed ripe bananas until they are evenly distributed throughout the batter. If you wish to add 1 cup of chopped toasted walnuts (or other add-ins like chocolate chips), fold them in at this stage.
- Pour the prepared batter evenly into your lined 9×9-inch baking pan. Bake for 35 to 45 minutes, or until a toothpick inserted into the center of the cake comes out with only a few moist crumbs attached. The top should be golden brown and the edges slightly pulled away from the sides of the pan.
- While the cake base is baking and then cooling, prepare the delightful banana pudding frosting. In a medium bowl, whisk together the instant banana pudding mix and whole milk according to package directions until smooth and slightly thickened. Alternatively, for an even creamier, lighter topping, prepare our Cool Whip Pudding Frosting. Place the pudding in the refrigerator to chill and set further while your cake cools completely.
- Once the banana cake base has cooled completely to room temperature, retrieve the chilled pudding frosting. Spread the banana pudding layer evenly over the top of the cake, ensuring full coverage. For the best texture and to allow the pudding to fully set, refrigerate the entire cake for at least 2 hours before slicing and serving. This allows the flavors to meld beautifully and the frosting to firm up.

Important Considerations for Your Banana Cream Cake
Does Banana Cream Cake Need to Be Refrigerated?
Absolutely, yes! Any baked good that incorporates fresh fruit, dairy products, or delicate fillings like whipped cream, cream cheese frosting, custard, or pudding must be refrigerated. These perishable ingredients are prone to spoilage if left at room temperature for extended periods. Refrigeration is crucial not only for preserving the cake’s freshness and flavor but also for ensuring food safety and preventing the growth of harmful bacteria. Always store your banana cream cake in an airtight container in the refrigerator to maintain its quality and extend its shelf life.
Is it OK to Use Black Bananas to Bake With?
Black bananas are perfectly safe and often even superior for baking, provided they show no signs of mold or an unpleasant smell. The ideal stage for baking is when bananas are a very deep, rich brown, just before they turn completely black. At this point, their natural sugars are fully developed, contributing immense sweetness and moisture to your cake. If your bananas are ripening too quickly and you’re not ready to bake, you can slow down the process significantly by placing them in a bowl in the refrigerator for a few days. This will buy you time until you’re ready to create your delicious banana treat.
Can Dogs Eat Bananas?
While bananas can be a healthy and safe treat for dogs when given in moderation, it’s always best to consult with your veterinarian before introducing any new food into your pet’s diet, especially if they have known allergies or sensitivities. Generally, bananas are low in cholesterol and sodium and are a good source of beneficial nutrients like potassium, vitamin C, vitamin B6, and fiber. They can be a great natural snack, but moderation is key due to their sugar content.
How Long Does a Cake with Fruit Last?
A cake containing fresh fruit, especially one with a moist topping like pudding frosting, is best enjoyed within 3 days. It can typically last up to 5 days if properly refrigerated and stored in a tightly sealed container to prevent it from drying out or absorbing other odors. However, it’s important to note that the texture of the cake will naturally evolve over time. Due to the moisture from the fruit and any wet toppings, the cake may become progressively gooier the longer it sits. For the freshest taste and best texture, aim to consume it within the first few days.

Why is My Banana Cake Not Moist?
The primary culprit behind a dry banana cake is almost always over-baking. Achieving the perfect moistness requires careful attention to baking time. Always set your timer for the minimum duration specified in the recipe. As soon as the cake’s center appears set and no longer looks wet, and it has risen beautifully, perform a toothpick test. Insert a toothpick into the very middle of the cake; it should come out with a few moist crumbs attached, not completely dry. A completely dry toothpick indicates your cake is already over-baked.
Furthermore, proper cooling technique is essential for retaining moisture. Once your cake is out of the oven, do not let it sit in the hot pan for too long. Have a wire cooling rack ready on your countertop. Allow the cake to rest in the pan for no more than 5 minutes. This brief period helps it firm up slightly. Then, carefully lift the cake out of the pan using the parchment paper overhang and transfer it immediately to the wire rack to cool completely. Leaving the cake in the hot pan for too long will cause the residual heat to continue baking it, inevitably leading to a dry and crumbly result. Follow these tips for a consistently moist, tender, and delicious banana snack cake every time!
