Ingredients
This recipe makes about 12 servings.
For the Double Chocolate Banana Cake
- 2 ½ cups (300g) all-purpose flour
- ¾ cup (75g) unsweetened cocoa powder
- 1 ½ teaspoons baking soda
- ½ teaspoon salt
- 1 cup (226g) unsalted butter, softened
- 1 ¾ cups (350g) granulated sugar
- 2 large eggs, at room temperature
- 1 cup (240ml) buttermilk, at room temperature
- 1 teaspoon vanilla extract
- 1 ½ cups (about 3-4 medium) very ripe mashed bananas
- 1 cup (170g) semi-sweet chocolate chips
For the Chocolate Ganache Frosting
- 1 ½ cups (360ml) heavy cream
- 12 ounces (340g) good quality semi-sweet chocolate, finely chopped
- 2 tablespoons (28g) unsalted butter, softened
- 1 teaspoon vanilla extract
- ¼ cup (30g) powdered sugar (optional, for extra sweetness)
Step-by-Step Instructions
-
Step 1: Get Ready!
Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans. You can also line the bottoms with parchment paper for easy removal. This step is key for preventing sticking.
Small tip: Use a light-colored pan for more even baking. Darker pans can cause the edges to brown too quickly.
-
Step 2: Dry Ingredients Mix
In a large bowl, whisk together the flour, cocoa powder, baking soda, and salt. Make sure there are no lumps. Set this bowl aside for a moment.
Small tip: Sifting your dry ingredients can help make your cake even lighter and fluffier.
-
Step 3: Wet Ingredients Blend
In a separate large bowl, using an electric mixer, cream together the softened butter and granulated sugar until light and fluffy. This usually takes about 2-3 minutes. Beat in the eggs one at a time, making sure each is fully incorporated before adding the next. Stir in the buttermilk and vanilla extract, then fold in the mashed bananas.
Small tip: Overripe bananas with lots of brown spots are best for this recipe; they add more natural sweetness and moisture.
-
Step 4: Combine & Mix
Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Be careful not to overmix! Overmixing can lead to a tough cake. Gently fold in the semi-sweet chocolate chips.
Small tip: Stop mixing as soon as you no longer see streaks of flour. A few small lumps are fine.
-
Step 5: Bake the Layers
Divide the batter evenly between your two prepared cake pans. Smooth the tops with a spatula. Bake for 25-30 minutes, or until a wooden skewer inserted into the center comes out clean. Let the cakes cool in the pans for 10 minutes, then invert them onto a wire rack to cool completely. This prevents them from getting soggy.
Small tip: Make sure the cakes are completely cool before frosting, otherwise your ganache will melt!
-
Step 6: Make the Ganache Frosting
While the cakes cool, prepare your ganache. Heat the heavy cream in a small saucepan over medium heat until it just begins to simmer around the edges. Remove from heat and pour it over the finely chopped chocolate in a heatproof bowl. Let it sit for 5 minutes, then whisk gently until smooth and glossy. Stir in the softened butter, vanilla extract, and powdered sugar (if using) until fully combined. Let the ganache cool at room temperature for about 30-60 minutes, stirring occasionally, until it thickens to a spreadable consistency. It should be thick enough to hold its shape but still pourable.
Small tip: If your ganache gets too thick, you can gently warm it over a double boiler for a few minutes. If it’s too thin, chill it in the fridge for 15-20 minutes, stirring every 5 minutes.
-
Step 7: Assemble the Cake
Once the cakes are fully cooled and the ganache is ready, it’s time to assemble! If your cake layers have domed tops, you can carefully level them with a serrated knife. Place one cake layer on your serving plate or cake stand. Spread about one-third of the ganache evenly over the top. Place the second cake layer on top, and then spread the remaining ganache over the top and sides of the cake. Make it as smooth or as rustic as you like!
Small tip: For a professional look, use an offset spatula to spread the frosting. A rotating cake stand also helps immensely.
-
Step 8: Chill & Serve
For the best results, chill the assembled cake in the refrigerator for at least 30 minutes to allow the ganache to set. This makes for cleaner slices. Once set, slice and serve immediately. Enjoy your magnificent creation!
Small tip: Warm your knife under hot water and wipe it clean between each slice for beautifully neat pieces of cake.
Tips & Variations
- Gluten-Free Option: Swap the all-purpose flour for a 1:1 gluten-free baking flour blend. Make sure your blend contains xanthan gum, or add ½ teaspoon per cup of flour.
- Vegan Option: Replace eggs with flax eggs (1 tbsp ground flaxseed + 3 tbsp water per egg, let sit for 5 minutes). Use plant-based buttermilk (almond milk + 1 tbsp vinegar), vegan butter, and dairy-free chocolate chips. For the ganache, use full-fat canned coconut cream (chilled, scoop out thick cream) instead of heavy cream, and vegan chocolate.
- Add More Goodness: For a hidden boost, grate about ½ cup of zucchini into the wet ingredients – you won’t taste it, but it adds moisture and nutrients! You could also stir in ½ cup of chopped walnuts or pecans for extra crunch and healthy fats.
- Spicy Chocolate Kick: For an intriguing flavor, add ¼ teaspoon of cayenne pepper or chili powder to the dry ingredients. It won’t make it overtly spicy, but it will enhance the chocolate flavor with a subtle warmth.
- Flavor Variations: Stir 1-2 teaspoons of instant espresso powder into the wet ingredients for a richer, deeper chocolate flavor. You could also add a hint of orange zest to the batter or frosting for a lovely citrus note.

Health Benefits
While this is a delicious treat, it still packs some beneficial ingredients! Let’s look at a few.
Bananas are a fantastic source of potassium, which is essential for heart health and maintaining fluid balance in the body. They also provide dietary fiber, aiding in digestion, and are rich in Vitamin B6 and Vitamin C, supporting immune function and energy metabolism.
Dark chocolate, especially the kind used in this recipe, is loaded with antioxidants called flavonoids. These powerful compounds can help protect your cells from damage and may contribute to improved heart health. Chocolate also contains compounds that can boost your mood, making this cake a true feel-good treat!
Eggs, if you’re not opting for the vegan version, are a great source of high-quality protein, which is vital for muscle repair and growth. They also contain choline, an important nutrient for brain health and metabolism.
Even in a dessert, you’re getting some fiber from the bananas and potentially from the whole grains if you choose a whole wheat flour blend. Remember, enjoying treats in moderation is part of a balanced lifestyle!
Serving Suggestions
- Serve a slice with a scoop of vanilla bean ice cream or a dollop of fresh whipped cream for an extra decadent dessert.
- Pair it with a hot cup of coffee, a comforting tea, or a cold glass of milk for the perfect afternoon pick-me-up.
- Garnish individual slices with a dusting of cocoa powder, a few fresh banana slices, or some extra chocolate shavings for a beautiful presentation.
Storage Tips
Your Double Chocolate Banana Layer Cake will keep wonderfully in an airtight container in the refrigerator for up to 3-5 days. The flavors often deepen beautifully overnight! You can also freeze individual slices or the whole cake (unfrosted is best, or with a very firm ganache) for up to 2-3 months. Wrap it tightly in plastic wrap, then in foil. To reheat, simply bring slices to room temperature for about 30-60 minutes before serving. If frozen, thaw overnight in the refrigerator, then bring to room temperature.
