  • 3/4 cup unsweetened cocoa powder
  • 2 teaspoons baking soda
  • 1 teaspoon baking powder
  • 1/2 teaspoon salt
  • 2 large eggs, at room temperature
  • 1 cup buttermilk
  • 1/2 cup vegetable oil
  • 1 teaspoon vanilla extract
  • 1 1/2 cups granulated sugar

  • 1/2 cup heavy cream
  • 2 teaspoons vanilla extract (for frosting)
  • 1 pinch salt (for frosting)
  • Chocolate shavings (for garnish)

Instructions

  1. Preheat your oven to 350°F (175°C). Grease and line two 9-inch round cake pans with parchment paper.
  2. In a bowl, whisk together the flour, cocoa powder, baking soda, baking powder, and salt. Set aside.
  3. In a large bowl, beat the eggs, granulated sugar, buttermilk, oil, and vanilla until smooth.
  4. Stir in the mashed bananas until mixed.
  5. Gradually mix the dry ingredients into the wet mixture, stirring until just combined.
  6. Divide the batter evenly between the prepared pans and bake for 30-35 minutes, or until a toothpick comes out clean.
  7. Allow the cakes to cool in the pans for 15 minutes before transferring to wire racks to cool completely.
  8. For the frosting, beat butter until creamy, then gradually add powdered sugar and cocoa, mixing well. Stir in heavy cream, vanilla, and salt until fluffy.
  9. Once the cakes are cool, place one layer on a serving platter, frost, add the second layer, and frost the top and sides. Garnish with chocolate shavings and banana slices.
  10. Chill for 30 minutes before slicing to set the frosting.
