Ingredients for banana oreo cake
Fudgy banana cake layers meet crispy Oreo crust in this decadent dessert masterpiece.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for even texture |
| Granulated Sugar 🍚 | 2 cups | White or light brown |
| Ripe Bananas 🍌 | 3 large | Mashed thoroughly |
| Unsalted Butter 🧈 | 1 cup | Room temperature, softened |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Vanilla Extract 🌿 | 2 tsp | Pure extract preferred |
| Baking Soda 🧂 | 1 tsp | Pure baking soda |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Oreos 🍪 | 24 whole | Crushed for crust |
| Melted Butter 🧈 | ½ cup | For crust binding |

The bananas are the heart of this cake—choose ones that are ripe but not mushy, with brown spots and a slight give when pressed. Trader Joe’s and Whole Foods often carry ideal bananas for baking. For the Oreos, avoid the mini versions—they’re too small and won’t create the same satisfying crunch. The cream cheese frosting relies on full-fat cream cheese for that luscious, spreadable texture. If you’re in a hurry, Philadelphia brand is widely available and reliable.
No ripe bananas? Use 1 cup of applesauce as a substitute, but expect a slightly denser texture. Swapping out Oreos? Crushed graham crackers or chocolate cookies work well, though the flavor will differ. For a gluten-free option, ensure your flour blend contains xanthan gum to mimic the structure. The frosting can be made ahead and stored in the fridge for up to 3 days—just rewhip before using. If you prefer a lighter frosting, increase the powdered sugar to 3.5 cups and reduce the cream cheese slightly.
This cake keeps beautifully for 4-5 days at room temperature, covered loosely with plastic wrap. For longer storage, freeze the entire cake (unfrosted) for up to 3 months. Thaw overnight in the fridge before frosting. The frosting can be piped directly onto the cake layers, or you can spread it evenly for a classic look. Garnish with extra crushed Oreos or banana slices just before serving for that restaurant-quality finish.

Step-by-step instructions for banana Oreo cake
Master this decadent dessert with layers of moist banana cake and Oreo cookie crust.
Prepare the Oreo Cookie Crust
Preheat your oven to 350°F and grease an 8-inch round springform pan. In a food processor, pulse the 24 whole Oreos until you achieve a fine, even crumb texture—about 15-20 seconds. Transfer the crumbs to a medium bowl and stir in the 0.5 cup melted butter until fully combined and the mixture holds together when pressed.
Press the Oreo mixture firmly and evenly into the bottom of your prepared pan, creating a compact, ¼-inch thick crust. Use the back of a measuring cup to ensure even distribution. Bake for 8-10 minutes until the edges are lightly golden. Remove from the oven and let cool completely while you prepare the cake layers.
Mix the Banana Cake Batter
In a large mixing bowl, combine the 3 large ripe bananas and 2 cups granulated sugar. Mash the bananas thoroughly with a fork until smooth, then whisk in the 2 whole large eggs and 2 teaspoons vanilla extract. The mixture should be thick and well-blended—this ensures a tender cake texture.
In a separate bowl, sift together the 2.5 cups all-purpose flour, 1 teaspoon baking soda, and 0.5 teaspoon salt. Gradually whisk the dry ingredients into the banana mixture in 3 additions, mixing just until combined. Be careful not to overmix—small lumps are fine. Fold in the 1 cup softened unsalted butter using a spatula until evenly distributed throughout the batter.
Bake the Cake Layers
Divide the batter evenly between two 6-inch round cake pans that have been lightly greased and lined with parchment rounds. Bake in the preheated 350°F oven for 25-30 minutes, or until a toothpick inserted into the center comes out clean and the edges pull away slightly from the pan. Rotate the pans halfway through baking for even cooking.
Allow the cake layers to cool in their pans for 10 minutes, then transfer to a wire rack to cool completely. This gradual cooling prevents cracking and ensures clean layering. Once fully cooled, carefully remove the layers from their pans using the parchment rounds for support.
Assemble the Cake
Place one cake layer onto the cooled Oreo crust in your springform pan. Spread a thin layer of cream cheese frosting (made by beating the 8 oz softened cream cheese, 3 cups powdered sugar, 0.5 cup cold heavy cream, and 1 teaspoon vanilla extract until smooth) over the top. Repeat with the second cake layer, adding another layer of frosting on top.
Gently press down on the top layer to create a level surface. Spread the remaining frosting evenly over the entire cake, creating a smooth, ¼-inch thick layer. Use a bench scraper to create clean edges. Chill the assembled cake in the refrigerator for at least 2 hours before serving to allow the frosting to set properly.
Pro Tips For Making Banana Oreo Cake
- Mash Bananas Thoroughly: I learned this the hard way—lumpy mashed bananas mean a cake with uneven texture and pockets of undercooked dough. Use a fork first to break them up, then press through a fine-mesh sieve or blend briefly if you’re impatient (but don’t overdo it—you don’t want banana puree). The goal is a smooth, thick puree that mixes like butter, not a chunky paste.
- Weigh Your Butter: Pack that butter into the measuring cup before scooping—don’t just eyeball it. Too little butter means a dry cake; too much makes it greasy and dense. I skip the softening step entirely: just scoop cold butter straight from the fridge, pack it firmly, and let it sit at room temp for 10 minutes while you prep. No waiting for it to melt into a mess.
- Check Oven Temp Early: Preheat your oven to 350°F (175°C) and then immediately stick an oven thermometer in the center rack. Most home ovens run hot, and this cake relies on even baking—if it’s 50°F off, your edges will burn before the center sets. I’ve ruined three banana cakes this way; now I adjust the temp by 25°F if the thermometer reads high.
- Fold Oreo Crumbs Gently: Dump the crushed Oreos into the batter and stop stirring. Use a spatula to fold them in just until combined—overmixing develops gluten and turns your cake dense. My grandmother swore by this, and she was right: the crumbs should stay mostly whole, like little pockets of flavor. If the batter looks streaky, that’s fine—it’ll even out when baked.
Essential equipment for this dish
Must-Have Mixing Tools
Start with a stand mixer or hand mixer—I recommend the KitchenAid Artisan Series for its reliable performance and sturdy build. This will handle both the cake batter and frosting with ease. For the Oreo crust, a food processor (like the Ninja BN601) is essential for achieving that perfect fine crumb texture. If you don’t have a food processor, a ziplock bag and rolling pin work in a pinch—just place Oreos in the bag and crush them with the pin. 🌾
Baking Essentials
A springform pan (8-inch) is critical for this recipe—it allows for easy removal of the cake layers and keeps the Oreo crust intact. I use Wilton’s Non-Stick Springform Pan because it releases cleanly. For the cake layers, two 6-inch round cake pans are needed, preferably with removable bottoms for easy transfer. Grease them well with butter or baking spray to prevent sticking. A parchment round in each pan ensures the cake doesn’t adhere to the bottom.
Frosting & Assembly
For smooth frosting, a pipeline bag with a star tip (like the Ateco 1M) makes piping effortless, but a bench scraper (I love the OXO Good Grips) is a game-changer for creating clean edges. If you prefer spreading, a spatula with a flexible edge works just as well. A wire rack is non-negotiable for cooling layers properly—it prevents sogginess and ensures clean cuts. For chilling the assembled cake, a large baking sheet or cake stand keeps it stable while the frosting sets. ✨
Optional Upgrades
Invest in a digital kitchen scale (like the OXO Good Grips) for precise measurements, especially when working with cream cheese frosting. A thermometer ensures your butter and cream cheese are at the perfect room temperature (around 68°F). For extra flair, a pastry brush helps with glazing or adding a light dusting of powdered sugar. If you’re garnishing with banana slices, a sharp serrated knife (like the Mercer Culinary Genesis) gives clean cuts every time. 🍌
Budget-Friendly Swaps
No mixer? A hand whisk and strong arm will work for the batter. Skip the food processor by crushing Oreos in a ziplock bag with a rolling pin. For frosting, a fork or wooden spoon beats the cream cheese and powdered sugar until smooth. A pie server can replace a bench scraper for leveling frosting. The most critical budget item is the springform pan—if you can’t splurge, a well-greased standard round pan with parchment works, but removing the cake may be trickier. 💪

Frequently asked questions
Can I make this banana Oreo cake without a food processor?
Crush the Oreos by placing them in a ziplock bag and using a rolling pin or heavy pan to pulverize them into fine crumbs. For even finer texture, transfer to a bowl and press with a fork. This method works just as well and requires no special equipment.
How do I keep the cake layers from getting soggy?
Let the cake layers cool completely before assembling, and chill the cake for at least 2 hours in the fridge. Use a thin layer of frosting between layers to prevent moisture transfer. If your kitchen is warm, extend the chilling time to 3-4 hours for perfect texture.
What can I substitute for cream cheese frosting?
Try a vanilla buttercream (made with butter, powdered sugar, and milk) or chocolate ganache for a richer flavor. For a lighter option, whipped cream with powdered sugar works beautifully. Just adjust consistency to match the original frosting's thickness.
Can I bake this cake in a different pan size?
Yes, but adjust baking times slightly. For a 9-inch pan, reduce time by 5-7 minutes per layer. For 6-inch pans, increase by 3-5 minutes. Always use a toothpick test to check doneness. The key is even heat distribution—rotate pans halfway through baking.
Why did my Oreo crust turn crumbly instead of crispy?
This usually happens when the butter isn't melted enough or the crust wasn't pressed firmly. Next time, ensure the butter is completely liquid (not just softened) and press the crust tightly into the pan. Bake for 1-2 extra minutes if needed for better set.
