👩🍳 Instructions
1. Prepare the Cake Batter
Preheat your oven to 350°F (180°C). Grease and line two 9-inch round cake pans with parchment paper.
In a large mixing bowl, combine the flour, cocoa powder, sugar, baking powder, baking soda, and salt. Whisk the dry ingredients together until evenly mixed.
In another bowl, whisk the eggs, milk, vegetable oil, and vanilla extract until smooth.
Gradually pour the wet ingredients into the dry ingredients while mixing. Stir until the batter becomes smooth and well combined.
Finally, add the hot coffee (or hot water) slowly while stirring. The batter will be thin, which is normal and helps create a moist cake.
2. Bake the Cake
Divide the batter evenly between the prepared cake pans.
Bake in the preheated oven for 30–35 minutes, or until a toothpick inserted into the center comes out clean.
Remove the cakes from the oven and allow them to cool in the pans for about 10 minutes, then transfer them to a wire rack to cool completely before assembling.
3. Prepare the Cream Filling
In a chilled mixing bowl, add the heavy whipping cream, powdered sugar, and vanilla extract.
Using an electric mixer, whip the cream until soft peaks form and the mixture becomes thick and fluffy. Keep refrigerated until ready to use.
4. Prepare the Chocolate Ganache
Heat the heavy cream in a small saucepan until it just begins to simmer (do not boil).
Pour the hot cream over the chocolate chips in a heatproof bowl. Let it sit for 2 minutes, then stir until smooth and glossy.
Add the butter and mix until fully melted and shiny. Let the ganache cool slightly so it thickens before pouring over the cake.
5. Assemble the Cake
Place the first chocolate cake layer on a serving plate or cake stand.
Spread a generous layer of whipped cream over the cake. Arrange sliced bananas evenly across the cream.
Place the second cake layer on top and spread another layer of cream if desired.
Slowly pour the chocolate ganache over the top, allowing it to drip down the sides for a beautiful effect.
6. Decorate the Cake
Top the cake with fresh banana slices, chocolate shavings, or a sprinkle of cocoa powder for a stunning presentation.
Refrigerate the cake for 30–60 minutes before serving so the layers set properly.

✨ Use very ripe bananas for the sweetest flavor and best texture.
