Instructions
 

Preparation

  • Preheat your oven to 350°F (175°C) and grease and flour two 8-inch cake pans.
  • In a large mixing bowl, combine the mashed bananas, granulated sugar, brown sugar, vegetable oil, eggs, and vanilla extract. Beat until well blended.
  • In a separate bowl, whisk together the all-purpose flour, cocoa powder, baking powder, baking soda, and salt.
  • Gradually add the dry mixture to the wet ingredients, alternating with the buttermilk until you have a well-combined batter.
  • Gently fold in the chocolate chips.
  • Divide the batter equally between the prepared cake pans.

Baking

  • Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean.
  • Let the cakes cool in the pans for 10 minutes before transferring to a wire rack to cool completely.

Frosting and Serving

  • Once cooled, layer and frost the cake as desired.

Notes

For added crunch, consider folding in chopped walnuts or hazelnuts with the chocolate chips. Letting the cake sit for a few hours or overnight enhances the flavors.
