Ingredients

  • 1 cup over-ripened bananas mashed
  • 1/4 cup sour cream or plain Greek yogurt
  • 1 tsp. pure vanilla extract
  • 2 cups sifted white flour
  • 1 tsp. baking soda
  • 3/4 tsp. baking powder
  • 1/4 cup cocoa powder
  • 3 tbsp. hot water or more if needed
  • 1 1/2 stick unsalted butter
  • 3/4 cup sugar
  • 2 large eggs

Instructions

  • Preheat the oven to 350°.
  • Coat a loaf pan with non-stick cooking spray.
  • Mash bananas in a small bowl. Add the sour cream and vanilla to the bananas and whisk just until blended. Set aside.
  • Sift the flour, baking soda and baking powder together into a medium bowl. Stir to combine. Set aside.
  • Place the cocoa powder in the small bowl. Pour the boiling water over the cocoa and stir until it forms a smooth paste.
  • If it is too thick, add a little more water and stir. Set aside.
  • Place butter and sugar in a large bowl. Beat on medium speed until the butter is light and combined with sugar.
  • Add the eggs one at a time and continue beating at medium speed.
  • Bring mixer speed down to low and gradually begin to add flour.
  • Add a little banana mixture at a time. Then, continue adding flour and banana mixture until blended.
  • Transfer half of the batter to the bowl with your cocoa paste and blend it together.
  • Drop alternating spoonfuls of dark and light batters into the prepared pan.
  • Marbleize batter by gently swirling batter down the length of the pan. Tap pan gently to even out the batter.
  • Bake the banana bread for about 60 minutes until a toothpick inserted comes out clean.
  • Allow to cool before slicing and serving.
