🧂 Ingredients:

  • 1 3/4 cups flour (220 g)
  • 3/4 cup cocoa powder (60 g)
  • 1 1/2 teaspoons baking powder
  • 1 1/2 teaspoons baking soda
  • 1/2 teaspoon salt
  • 3 large, very ripe bananas (mashed – ~1 1/4 cups)
  • 1 cup sugar (200 g)
  • 1/2 cup brown sugar (100 g)
  • 2 large eggs
  • 1/2 cup milk
  • 1/2 cup yogurt or sour cream
  • 1/2 cup vegetable oil
  • 1 teaspoon vanilla extract
  • 1/2 cup hot water or hot coffee
  • 1 cup chocolate chips
  • 200 g butter (at room temperature)
  • 2 1/2 cups powdered sugar
  • 3/4 cup cocoa powder
  • 100 g melted dark chocolate (cooled)
  • 4–6 tablespoons milk (for the frosting)

👩‍🍳 Directions:

  1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
  2. Mix Dry Ingredients: In a large bowl, sift together the flour, cocoa powder, baking powder, baking soda, and salt. Set aside.
  3. Combine Wet Ingredients: In another bowl, mash the ripe bananas until smooth. Stir in both sugars, eggs, milk, yogurt (or sour cream), vegetable oil, and vanilla extract. Mix until well combined.
  4. Combine Ingredients: Gradually add the dry ingredients to the wet mixture, alternating with hot water or coffee. Stir gently until just combined. Be careful not to overmix.
  5. Fold in Chocolate Chips: Gently fold in chocolate chips until evenly distributed throughout the batter.
  6. Bake: Divide the batter evenly between the prepared cake pans. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean.
  7. Cool: Let the cakes cool in the pans for about 10 minutes, then transfer them to wire racks to cool completely.
  8. Prepare the Frosting: In a large bowl, beat the butter until creamy. Gradually add powdered sugar and cocoa powder, mixing on low speed until combined. Add cooled melted dark chocolate and enough milk to achieve a smooth frosting consistency. Beat on high speed until fluffy.
  9. Assemble the Cake: Once the cakes are completely cool, place one layer on a serving plate. Spread a generous amount of frosting on top. Place the second layer on top and frost the top and sides of the cake.
  10. Serve and Enjoy: Decorate with additional chocolate chips or drizzles of melted chocolate if desired. Slice, serve, and indulge in the rich flavors!
