Ingredients

Scale
  • 1 3/4 cups all-purpose flour
  • 1/2 cup unsweetened cocoa powder
  • 1 tsp baking soda
  • 1/2 tsp baking powder
  • 1/2 tsp salt
  • 1/2 cup unsalted butter, softened
  • 1 cup granulated sugar
  • 2 large eggs
  • 1 tsp vanilla extract
  • 1/2 cup sour cream
  • 3 ripe bananas, mashed
  • 1/2 cup milk
  • 1 cup heavy whipping cream (for frosting)
  • 1/2 cup semi-sweet chocolate chips or chopped chocolate (for frosting)
  • 2 tbsp powdered sugar (for frosting)

Instructions

  1. Preheat oven to 350°F (175°C). Grease and flour two 8-inch round cake pans or a 9×13-inch pan.
  2. In a bowl, whisk together flour, cocoa powder, baking soda, baking powder, and salt.
  3. In a large bowl, cream butter and sugar until light and fluffy.
  4. Add eggs one at a time, beating well, then stir in vanilla.
  5. Mix in mashed bananas and sour cream until well combined.
  6. Alternately add dry ingredients and milk to the batter, mixing until just combined.
  7. Pour batter into prepared pan(s) and bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean.
  8. Cool completely in pans for 10 minutes, then transfer to wire racks.
  9. For frosting: Heat chocolate in the microwave or a double boiler until melted, then cool slightly.
  10. Whip cream with powdered sugar until soft peaks form. Fold in cooled melted chocolate until smooth and fluffy.
  11. Frost the cooled cake with chocolate cream frosting. Decorate as desired.

Notes

  • Use very ripe bananas for the best flavor and moisture.
  • For extra texture, fold in chocolate chips or chopped nuts into the batter.
  • Store cake in the refrigerator due to the whipped cream frosting.
  • Let the cake sit at room temperature for 10–15 minutes before serving for best texture.
