These double chocolate espresso banana muffins are light, fluffy and super rich. This recipe calls for cocoa powder, dark chocolate chunks and ripe bananas.

Ingredients

Units Scale
  • 2 ripe bananas, mashed (about 2/3 cup)
  • 2 eggs, room temperature
  • 1/2 cup salted butter, melted and cooled
  • 2 cups all-purpose flour, spooned and leveled
  • 1/2 cup unsweetened cocoa powder
  • 1/2 cup granulated sugar
  • 2 teaspoons baking powder
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon kosher salt
  • 1/4 cup hot water
  • 2 teaspoons espresso powder
  • 3/4 cup whole milk, room temperature
  • 1 teaspoon apple cider vinegar (optional)
  • 1 cup chocolate chips or chunks
  • 1/2 cup mini chocolate chips

Instructions

  1. In a mixing bowl, mash ripe bananas. Add eggs and stir to combine. Pour in melted, but slightly cooled butter and stir to combine. 
  2. In a glass measuring cup, heat water in the microwave until hot. Add espresso powder to hot water and whisk to combine. Pour milk into the measuring cup until you reach the 1-cup line. Stir in apple cider vinegar and set aside.
  3. To the mixing bowl, add dry ingredients and partially combine. Pour in the milk mixture and stir to combine. Use a rubber spatula to scrape the sides of the bowl. 
  4. Mix in the chocolate chips. Do not overmix. Let the batter rest while you prepare a muffin tin. 
  5. Preheat the oven to 425°F. Line a muffin tin and use a large scoop to portion out into equal-sized muffins. Depending on your size tin, this recipe makes 12-15 muffins. Top each muffin with a few mini chocolate chips.
  6. Bake muffins at 425°F for about 8 minutes. This gives your muffins a nice domed top. Reduce oven temperature to 325°F and bake muffins for an additional 10-12 minutes.

Notes

If not using espresso powder, skip espresso and water. Use 1 cup of milk instead of 3/4 cup. 

If not using muffin liners, grease your muffin tin with cooking spray or oil and dust with cocoa powder before scooping in your batter!
