Chocolate Banana Muffins

  • 1 medium-to-large over-ripe banana
  • 3 tablespoons (1.5oz) unsalted butter melted
  • 1/4 cup (50g) brown sugar
  • 1 large egg white
  • 1/2 teaspoon vanilla extract
  • 1/3 cup (40g) all-purpose flour measured by weight or using the spoon and sweep method*
  • 3 tablespoons (15g) unsweetened cocoa powder
  • 1/2 teaspoon baking soda
  • 1/8 teaspoon salt
  • 2 ounces semi-sweet chocolate chopped or 1/3 cup chocolate chips, plus more for topping


  • Preheat your oven to 425°F and line a muffin tin with 5 liners.
  • Place peeled banana in a medium bowl and mash it well with a fork or potato masher. Add melted butter and whisk until well combined. Add brown sugar, egg white, and vanilla. Mix well.
  • Place a fine-mesh strainer over the bowl and add flour, cocoa powder, baking soda, and salt to the strainer. Sift dry ingredients into the wet and use a spoon to mix until just combined. Stir in chopped chocolate or chocolate chips. Divide batter between prepared muffin cups, filling about 3/4 of the way full.
  • Bake for 8 minutes at 425°F before turning the oven temperature down to 350°F. Bake for an additional 6 to 9 minutes, until a toothpick inserted into the center of the muffins comes out with just a few crumbs.
  • Sprinkle extra chocolate over the top if desired. Cool in the pan for at least 10 minutes, and enjoy.


*Correct flour measurement is important in this recipe. For best results, measure by weight or the Spoon and Sweep Method (stir the flour in your container to fluff it up and then spoon it into your measuring cup, sweep excess off with the flat of a knife).
