Banana Cake With Chocolate Icing

Posted on

Chocolate banana cake combines the best parts of banana bread and chocolate cake into one amazing dessert.

We’re absolutely in love with the combination of chocolate and bananas. These two flavors are a match made in heaven, and this banana cake with chocolate icing is no exception. The cake starts with three layers of tender banana buttermilk cake, all topped with our favorite dark chocolate ganache. This cake is the ultimate chocolate-banana delight.


  1. Even Cake Layers: Distribute the batter evenly among the cake pans for uniform layers. Using a kitchen scale can help achieve precise results.
  2. Cooling Method: Cool the cake layers in the pans for about 10-15 minutes, then transfer to a wire rack. Cooling them in the pans helps retain moisture and prevent collapsing.
  3. Chilled Ganache: Chill the ganache in the fridge for about 30 minutes before icing the cake. This helps it set and hold its shape better when spreading.


Can I freeze the cake layers?
Yes, freeze the layers for up to 1 month. Wrap each cooled layer in plastic wrap and aluminum foil, then place in a freezer-safe bag or container. Thaw overnight in the refrigerator before assembling.

Can I substitute the buttermilk?
Yes, make a substitute by adding 1 tablespoon of lemon juice or vinegar to 1 cup of milk. Let it sit for 5-10 minutes before using.

How should I store the banana cake with chocolate icing?
Store the assembled cake in an airtight container at room temperature for up to 3 days. If it’s warm, store in the refrigerator to prevent the icing from melting.

Can I use milk chocolate for the ganache?
Yes, though dark chocolate is recommended for a richer flavor, milk chocolate can be used for a sweeter taste. Adjust the sugar amount accordingly.

Can I omit the almond extract?
Yes, you can leave out the almond extract. It adds a subtle nutty flavor, but the cake will still be delicious without it.
