Instructions
- Prepare the Cake Layers
Preheat your oven to 350°F (175°C). Grease and line two 9-inch cake pans with parchment paper.
In a medium mixing bowl, whisk together the flour, cocoa powder, baking soda, baking powder, and salt.
In a large bowl, whisk together the eggs, sugar, buttermilk, vegetable oil, and vanilla extract. Add the mashed bananas and stir until well combined.
Gradually fold the dry ingredients into the wet mixture until fully incorporated.
Divide the batter evenly between the two prepared cake pans.
Bake for 30–35 minutes or until a toothpick inserted in the center comes out clean.
Allow the cakes to cool completely on a wire rack before frosting.
- Make the Chocolate Frosting
In a large bowl, beat the softened butter until light and creamy.
Slowly add the powdered sugar and cocoa powder, mixing on low speed until incorporated.
Add the heavy cream, vanilla extract, and a pinch of salt. Beat until the frosting is smooth and fluffy.
- Assemble the Cake
Place one cake layer on a serving plate and spread an even layer of chocolate frosting on top.
Add the second cake layer and frost the top and sides of the cake evenly.
Garnish with chocolate shavings and fresh banana slices.
- Chill and Serve
Refrigerate the cake for at least 30 minutes before slicing to allow the frosting to set.
Slice, serve, and enjoy your rich and flavorful Double Chocolate Banana Cake!
Tips:
Use very ripe bananas for the best natural sweetness and banana flavor.
For added texture, sprinkle chopped nuts or mini chocolate chips between the layers.
