Ingredients
  

  • 1/2 cup butter melted and cooled
  • 1 cup sugar
  • 3 tablespoons unsweetened cocoa powder
  • 2 large eggs lightly beaten
  • 1 tablespoon 2% milk
  • 1 teaspoon vanilla extract
  • 1 cup all-purpose flour
  • 1 teaspoon baking powder
  • 1/4 teaspoon salt
  • 1 cup mashed ripe bananas (about 2.5–3 bananas)
  • 1/2 cup chopped walnuts
  • 1 medium ripe banana mashed (for banana layer)
  • 1/2 cup sugar (for banana layer)
  • 1/4 cup butter melted and cooled (for banana layer)
  • 1 cup all-purpose flour (for banana layer)
  • 1/4 teaspoon baking soda (for banana layer)
  • 1/4 teaspoon salt (for banana layer)
  • Confectioners' sugar for dusting (optional)

Instructions
 

  • Preheat your oven to 350°F. Grease a 13x9-inch baking pan and line it with parchment paper, then grease the parchment.
  • Prepare the chocolate layer: In a large bowl, mix the melted butter, sugar, and cocoa powder until smooth. Stir in the eggs, milk, and vanilla extract. Blend in the flour, baking powder, and salt, folding gently until combined. Stir in the mashed bananas and walnuts. Pour the batter into the prepared pan and spread evenly.
  • Prepare the banana layer: In another bowl, whisk together the mashed banana, sugar, and melted butter until smooth. Add the flour, baking soda, and salt, and mix until just combined. Drop the mixture by spoonfuls over the chocolate batter and swirl gently with a knife.
  • Bake for 35–40 minutes or until a toothpick inserted into the center comes out with moist crumbs. Allow to cool completely on a wire rack before cutting into squares.
  • Dust with confectioners’ sugar if desired, then serve and enjoy!
