  • Total Time: 1 hour 10 minutes
  • Yield: 8-10 Slices 1x


Units Scale
  • 4oz (1/ 2 Cup) Unsalted Butter, melted
  • 100 grams (1/2 Cup) Granulated Sugar
  • 50 grams (1/4 Cup) Brown Sugar
  • 2 Large Eggs, at room temperature
  • 1 Teaspoon Pure Vanilla Extract
  • 4oz (1/2 Cup) Sour Cream/ Greek Yogurt
  • 156 grams (1 1/4 Cups) All-Purpose Flour/ Plain Flour
  • 1/2 Teaspoon Baking Soda
  • 1 Teaspoon Baking Powder
  • 50 grams (1/2 Cup) Dutch-process Cocoa Powder
  • 1/2 Teaspoon Salt
  • 12oz (3 Medium) Very Ripe Bananas (measured without peel)
  • 180 grams (1 Cup) Chocolate Chips, divided


  1. Preheat the oven to 350F/180C and grease a 9"x 5" or 8.5" X 4.5" loaf pan.
  2. In a large bowl mix together the butter, sugars, eggs, vanilla extract, and sour cream.
  3. Add bananas and use a potato masher to mash them. Place a fine-mesh sieve over the bowl and sift in the flour, baking soda, baking powder, cocoa powder, and salt. Once almost combined fold in 3/4 of the chocolate chips.
  4. Pour into prepared pan. Sprinkle the remaining chocolate on top.
  5. Bake for 55-65 minutes. or until a toothpick inserted comes out clean. If you want to check the internal temperature with a digital thermometer you are looking for 205F/96C. Let cool for at least 30 minutes before removing it from the pan. Let cool on a wire rack. Store at room temperature unless you live in a warm climate store in the fridge.


You can use a 9"X5" loaf pan, I alternatively used an 8.5" X 4.5" 1lb loaf pan for a slightly taller loaf. Keep in mind using a smaller loaf will increase the baking time by another 5-10 minutes.
