Ingredients for banana pudding cookie recipe with cake mix

No oven needed—just cake mix, cookies, and bananas for this nostalgic dessert.

The cake mix is the star here, so any vanilla or yellow boxed mix works. I usually grab the Betty Crocker or Duncan Hines versions—they're reliable and affordable. For the wafers, Nabisco vanilla wafers are the classic choice, but any vanilla-flavored cookie crumbs will do. If you're feeling fancy, toast the crushed cookies lightly before mixing to enhance the flavor. The bananas need to be ripe—spotted skin means sweeter taste—but not so soft they turn to mush when sliced. Store them in the fridge until ready to use to keep them firm.

No vanilla wafers? Crushed graham crackers or digestive biscuits add a different but delicious texture. Short on vanilla extract? Almond extract at half the amount gives a nice twist. The pudding mix can be any brand, but Jell-O or Betty Crocker are widely available. For the whipped cream, if you don't have heavy whipping cream, cool regular cream in the fridge for 2 hours before whipping. The cherries and walnuts are optional but add that classic banana pudding touch—Trader Joe's or Costco usually have good prices on these.

This dessert keeps beautifully in the fridge for 3-4 days, though it's best enjoyed within 2 days for optimal texture. For make-ahead convenience, prep the layers separately and assemble just before serving. The cookie base stays crispy for about 1 hour at room temperature, so if you're serving it chilled, let it sit out for 10 minutes before digging in. Portion into individual cups for easy serving at parties—just add whipped cream on top when ready to serve.

Step-by-step instructions for banana pudding cookie recipe with cake mix

This no-bake dessert combines cake mix, pudding, and cookie crunch for a decadent treat.

In a medium bowl, whisk together the 0.5 cup milk and 1 box instant vanilla pudding mix for 2 minutes until completely smooth and thickened. This step is crucial—don't rush it, or you'll end up with a grainy texture. The mixture should coat the back of a spoon and hold its shape when spooned.

Once fully combined, fold in the 3 whole bananas (sliced into chunks) using a spatula. Gently mix until the bananas are evenly distributed throughout the pudding. Be careful not to overmix, as this could mash the bananas into a pulp. Set this mixture aside while you prepare the cake layer.

In a separate large bowl, combine the 1 box vanilla cake mix, 0.5 cup melted unsalted butter, 2 whole large eggs, 0.5 cup milk, and 1 tablespoon vanilla extract. Using an electric mixer on medium speed, beat for 2 minutes until the batter is smooth and fully incorporated. You should see no dry spots remaining in the bowl.

This batter will be slightly thicker than traditional cake batter due to the addition of melted butter. If it appears too thick, you can add 1 tablespoon additional milk to reach a spreadable consistency. The batter should be smooth enough to pipe or spread easily in the next step.

In a 9x13-inch baking dish, spread half of the cake batter evenly to create the bottom layer. The batter should be about ¼-inch thick when spread. Press down gently with a spatula to ensure even coverage.

Next, spread half of the pudding mixture over the cake layer, followed by half of the 2 cups crushed vanilla wafers. Repeat this process with the remaining cake batter, pudding mixture, and crushed vanilla wafers. The final layer should be crushed vanilla wafers to create that signature cookie crunch on top.

Cover the assembled baking dish tightly with plastic wrap and refrigerate for at least 4 hours, or until fully set. This chilling time is essential for the dessert to hold its shape and develop the proper texture. I recommend chilling overnight for the best results—it allows all the layers to meld together perfectly.

During the chilling process, the cake layer will firm up while the pudding layer will set completely. The crushed vanilla wafers will maintain their crunch, providing that delightful contrast with each bite. The dessert should feel firm to the touch when ready to serve.

Before serving, whip together the 1 cup heavy whipping cream, 0.25 cup granulated sugar, and 0.25 teaspoon salt until soft peaks form. Spread this whipped cream evenly over the chilled dessert.

Finally, sprinkle the top with the 0.5 cup chopped walnuts and 0.5 cup maraschino cherries for added texture and visual appeal. Serve immediately or return to the refrigerator for up to 2 hours before serving. Each slice should feature layers of moist cake, creamy pudding, and crunchy cookie pieces with the perfect balance of textures.

Common mistakes when making perfect results

Overmixing Pudding

When you whisk the pudding mix and milk, it’s easy to overmix and create lumps or a grainy texture. I’ve found that whisking for exactly 2 minutes at medium speed is key—no more, no less.

If you see any dry spots, let the mixture sit for 30 seconds before whisking again. The pudding should be smooth like thick pudding, not like batter. Overmixing also breaks down the bananas into mush, so fold them in gently with a spatula after the pudding is fully combined. 🥄

Skipping Chill Time

This is the biggest mistake I see—rushing the chilling process! The dessert needs at least 4 hours in the fridge to set properly. If you cut into it too soon, the layers will slide apart, and the cake base will be too soft.

I’ve learned the hard way that overnight chilling (up to 8 hours) gives the best texture. The pudding will hold its shape, and the cookie crunch stays crisp. Trust the process—patience pays off! ⏰

Uneven Layering

For a perfect bite, each layer must be spread evenly. I recommend using a spatula or offset spatula to press each layer down gently. If you don’t distribute the cake batter or pudding evenly, you’ll end up with thick spots that don’t set properly.

For the crushed cookies, sprinkle them lightly over the pudding—don’t pack them down, or they’ll lose their crunch. Think of it like building a sandwich: every layer should be consistent in thickness. 🍞

Using Cold Ingredients

Cold eggs, butter, or milk can make your cake batter lumpy and difficult to mix. Always use ingredients at room temperature—let eggs sit out for 30 minutes before using, and melt the butter gently in a microwave-safe bowl for 20 seconds.

Cold butter creates clumps that won’t incorporate smoothly, and cold milk can curdle the pudding mixture. A quick check: if your butter feels soft but not greasy, it’s ready. 🧈

Forgetting to Toast Cookies

If you toast your crushed cookies lightly before mixing them in, they’ll stay crispier longer. Spread them on a baking sheet and toast at 350°F for 3-5 minutes until they’re just golden. This step is optional but makes a huge difference in texture.

Untosted cookies can get soggy from the pudding, especially if you’re not chilling the dessert long enough. A quick toast adds that perfect crunch you crave in every bite. 🍪

Not Pressing Layers Down

After spreading each layer, press it down gently with the back of a spoon or spatula. This helps the layers adhere and prevents sliding. If you skip this step, the cake and pudding might separate when cutting.

For the final cookie layer, press it down just enough to hold the whipped cream on top. A little pressure goes a long way in keeping everything together. 💪
