Chocolate Banana Bread

  • 1 1/4 cups all-purpose flour leveled with a knife
  • 1/4 cup cocoa powder
  • 1 tsp baking soda
  • 1/4 tsp salt
  • 1 stick salted butter at room temperature
  • 1/2 cup sugar
  • 1/2 cup light brown sugar
  • 2 large eggs
  • 1 1/4 cup mashed bananas approximately 4 very ripe bananas
  • 1/2 cup sour cream
  • 1 tsp vanilla
  • 1/2 cup milk chocolate chips

Chocolate Topping

  • 1/3 cup milk chocolate chips
  • 2 tbsp whole milk
  • 3 tbsp powdered sugar


  • Preheat the oven to 350 degrees F. Grease a 9x5 loaf pan with cooking spray, set aside.
  • In a medium mixing bowl add the flour, cocoa powder, baking soda, and salt. Whisk to combine until there are no lumps remaining from the cocoa powder. Set aside.
  • In a large mixing bowl add the butter, sugar, light brown sugar, and eggs. Using a hand mixer on high, beat mixture for 2 minutes.
  • Add the mashed bananas, sour cream, and vanilla. Continue to beat together for another 1 to 2 minutes or until completely combined and no sour cream lumps remain. Use a rubber spatula to scrape down the sides of the bowl as needed.
  • Add the dry ingredients to the wet ingredients. Using the hand mixture on a low speed, beat together until no flour streaks remain. Use a rubber spatula to scrape down the sides of the bowl as needed.
  • Add the chocolate chips and use the rubber spatula to fold in the chocolate chips until combined.
  • Pour the batter into the greased loaf pan and spread evenly with a spatula.
  • Bake for 55 to 60 minutes. Test the center of the bread with a toothpick to see if it comes out clean. If not, continue to bake for an additional 5 to 10 minutes.
  • Remove the chocolate banana bread from the oven and let cool in the pan for 15 minutes. Run a knife around the edges of the pan to loosen the bread from the pan.
  • Turn out the bread onto a cooling rack and let cool completely before serving.
  • While the bread is cooling add the chocolate chips and whole milk to a small mixing bowl. Microwave for 15 seconds. Remove from the microwave and stir until all of the chocolate is melted.
  • Add the powdered sugar and whisk together. Let the chocolate topping sit out until the bread is completely cooled.
  • Once the bread is completely cooled, drizzle the chocolate topping over the bread and serve.
