Ingredients

The following ingredients have 12 Servings
  • 1/3 cup butter1 (1melted)
  • 1 cup mashed banana2
  • 1/2 cup brown sugar (packed)
  • 1/4 cup granulated sugar
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1 ½ cups all-purpose flour3 (properly measured)
  • 1 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1/4 cup unsweetened cocoa powder
  • 2 tablespoons milk

Instruction

  • Preheat the oven to 350F. Grease an 8x4-inch loaf pan. Set aside.
  • In a large bowl, whisk mashed banana and melted butter together until well-combined.
  • Whisk in sugars until incorporated.
  • Add egg and vanilla, and whisk until well-combined.
  • Stir in flour, baking soda, and salt until combined.
  • Remove 1 cup of batter to a separate mixing bowl.
  • Whisk in cocoa powder and milk until combined.
  • Pour 1/4 of the plain batter into the prepared pan.
  • Top the batter with 2 tablespoons chocolate batter.
  • Continue alternating batters on top of each other until you've used up both batters.
  • Give the pan a couple of gentle taps but don't stir.
  • Bake for 40-60 minutes, or until a wooden toothpick inserted into the center comes out clean. I check the bread around 30 minutes and tent with foil if it is browning too quickly.
  • Let cool in pan for a 5-10 minutes.
  • Remove bread to wire cooling rack, and let cool completely before slicing.
