Cooking Chocolate Banana Cake with Espresso Fudge Frosting: The Process

Step 1: Prepare Your Cake Pans
Start by greasing two 9-inch round cake pans with butter or non-stick spray. Line the bottoms with parchment paper for easy removal.
Step 2: Mix Dry Ingredients
In a medium bowl, whisk together the all-purpose flour, Dutch-processed cocoa powder, baking soda, salt, ground cinnamon, and espresso powder. Set this mixture aside.
Step 3: Cream Butter and Sugar
In a large mixing bowl, beat the unsalted butter and granulated sugar together using an electric mixer until light and fluffy, about 3-4 minutes.
Step 4: Add Eggs and Bananas
Add the eggs, one at a time, mixing well after each addition. Then, mix in the mashed ripe bananas and vanilla extract until fully combined.
Step 5: Incorporate Dry Ingredients
Gradually add the dry ingredients to the wet mixture, alternating with the sour cream. Start and end with the flour mixture. Be careful not to overmix; stop as soon as no flour streaks remain.
Step 6: Fold in Chocolate Chips
Gently fold in the chocolate chips, distributing them evenly throughout the batter.
Step 7: Bake the Cake
Divide the batter evenly between the prepared cake pans. Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out clean. Allow the cakes to cool in the pans for 10 minutes before transferring to a cooling rack to cool completely.
Step 8: Make the Espresso Fudge Frosting
While the cakes are cooling, prepare the frosting. In a medium saucepan, heat the heavy cream and 2 teaspoons of espresso powder over medium heat until just simmering. Remove from heat and add the finely chopped semi-sweet chocolate and 1 tablespoon of unsalted butter. Stir until smooth and glossy.
Step 9: Frost the Cake
Once the cake layers are completely cool, place one layer on a serving plate and spread a generous amount of frosting on top. Place the second layer on top and frost the top and sides of the cake with the remaining frosting.
Step 10: Serve and Enjoy
Slice the cake into pieces and serve! This Chocolate Banana Cake with Espresso Fudge Frosting is best enjoyed fresh, but it also holds up well for a couple of days at room temperature.
Flavor-Forward Alternatives

- Nutty Twist: Add 1/2 cup of chopped walnuts or pecans to the batter for a crunchy texture.
- Spicy Addition: Incorporate a pinch of cayenne pepper for a surprising kick.
- Fruit Fusion: Mix in 1/2 cup of shredded coconut for a tropical touch.
- Different Chocolate: Swap semi-sweet chocolate for dark chocolate for a richer taste.
Avoid These Mistakes
- Overmixing the batter can lead to a dense cake. Mix just until combined.
- Using unripe bananas will not provide the same level of sweetness and moisture. Choose fully ripe, brown bananas.
- Not letting the cake cool completely before frosting can cause the frosting to melt.
- Forgetting to measure ingredients accurately can affect the cake’s texture and flavor.
Meal Prep & Storage Notes
