Double Chocolate Banana Layer Cake
Chocolate, Bananas, and Big Memories: My Double Chocolate Banana Layer Cake
The first time I baked this Double Chocolate Banana Layer Cake, it was a rainy Sunday and the kitchen windows were all fogged up. My son and I had found three perfectly overripe bananas sitting on the counter—just begging to be made into something special. Instead of the usual banana bread, we went all out. Think rich cocoa layers, creamy chocolate frosting, and that unmistakable banana aroma filling the whole house. This banana chocolate cake instantly became our new family favorite (with a tall glass of milk on the side, naturally).
Nothing brings people together quite like a homemade chocolate layer cake—especially one that’s got the best of both worlds: deep, fudgy chocolate flavor and the cozy, comforting taste of ripe bananas. If you’ve been longing for a showstopping yet approachable cake recipe, this one’s just for you.

Ingredients You’ll Need for Double Chocolate Banana Layer Cake
Let’s gather what you’ll need—and I’ll throw in some of my favorite ingredient tips along the way.
- 3 ripe bananas, mashed
(The riper and browner, the better! Spotty bananas make your cake super moist and flavorful.) - 2 cups all-purpose flour
(Feel free to sift if you want an ultra-light crumb, but no biggie if you skip it.) - 3/4 cup cocoa powder
(Dutch-process cocoa makes this extra chocolatey, but any unsweetened cocoa works.) - 1 cup milk + 1 tsp lemon juice
(This turns your milk into “homemade buttermilk”—it keeps the cake soft.) - 2 eggs
(Room temp is best for even mixing.) - 1 cup granulated sugar + 1/2 cup brown sugar
(The brown sugar adds a hint of caramel that pairs so well with banana.) - 1/2 cup vegetable oil
(Keeps things ultra-moist—swap with melted butter if you want extra richness.) - 1 tsp vanilla extract
(A dash of warmth in every bite.) - 2 tsp baking powder + 1 tsp baking soda
(Lift and fluff galore!) - For the frosting:
- 1 stick unsalted butter, softened
- 3 cups powdered sugar
- 1/2 cup cocoa powder
- 1/2 cup melted dark chocolate
- 4-5 tbsp heavy cream (add for a softer, swoopy frosting texture)
Step-by-Step Guide: Making the Perfect Double Chocolate Banana Layer Cake
Ready to dive in? Here’s exactly how I make this luscious banana chocolate layer cake—easy, breezy, and full of helpful hints.
- Prep the pans.
Line two round cake pans (8 or 9-inch work great) with parchment and give them a swipe of oil or butter. - Mix dry ingredients.
In a big bowl, whisk together flour, cocoa, baking powder, and baking soda. (Cocoa clumps? Sift it first!) - Mash and mix.
In another bowl, mash up those bananas ‘til mostly smooth. Add in both sugars, eggs, oil, vanilla, and the “buttermilk” (just stir the lemon juice into the milk and let it sit for 3 minutes). Whisk until smooth. - Combine gently.
Add your banana mixture to the flour mixture. Stir with a spatula until you don’t see streaks—don’t overmix! - Divide & bake.
Pour into the prepared pans—try to eyeball it for even layers. Bake at 175°C (that’s about 350°F) for 30-35 minutes. The cakes are ready when a toothpick comes out mostly clean and the tops spring back. - Frosting time!
While the cakes cool, whip the butter with powdered sugar and cocoa until fluffy. Slowly mix in the melted chocolate. Add cream a tablespoon at a time until you’ve got silky, spreadable frosting. - Assemble & enjoy!
Once the cakes are cool, slather the frosting on the first layer, top with the second, and use the rest to cover and swirl. Go wild with sprinkles or banana slices if you’re feeling extra.
My Secret Tips and Tricks for Double Chocolate Banana Cake Success
Through many trial-and-error cakes (hey, the family’s never complained), here’s what makes this banana chocolate layer cake foolproof:
- Use overripe bananas. The more freckles, the stronger the banana flavor—so don’t pitch those blackened beauties!
- Measuring counts. For the flour, spoon it into your measuring cup and level it off (no compacting, or cake may turn dense).
- Room temp ingredients = smoother batter.
Cold eggs or milk straight from the fridge? Put them on the counter while you prep. - Don’t overbake! This chocolate banana cake should be just-set and a tiny bit springy. Check at the 30-minute mark.
- Frosting too thick? A little extra cream works magic. Too loose? Pop it in the fridge for 10 minutes.
- Decorating hack: Run a fork around the top for easy, rustic chocolate swirls (fancy piping not required).
Creative Variations and Ingredient Swaps
I love how flexible this recipe is. Here are some fun twists for your double chocolate banana cake:
- Nutty twist: Stir in a handful of chopped toasted walnuts or pecans for crunch.
- Dairy-free? Sub in almond or oat milk and use a dairy-free frosting option.
- Vegan option: Use flaxseed “eggs” and plant-based butter—works like a charm.
- Gluten-free: Your favorite 1:1 gluten-free flour blend will do the trick.
- Add-ins: Chocolate chips, peanut butter swirls, or a pinch of instant espresso powder (for mocha depth) all make for tasty upgrades.
- Frosting flavors: Try a peanut butter or cream cheese frosting with this chocolate banana cake for a whole new vibe.
How to Serve and Store Your Double Chocolate Banana Layer Cake
For the ultimate chocolate banana cake experience:
- Serve: Slightly warm with a scoop of vanilla ice cream, or at room temp with a dusting of cocoa powder.
- Storing leftovers:
- Wrap slices tightly in plastic wrap; they’ll stay moist on the counter for 2 days, or in the fridge up to 5.
- This banana chocolate cake also freezes beautifully. Wrap whole layers or slices in plastic and foil, then freeze for up to 2 months.
