Ingredients
 

Main Ingredients

  • 1.5 cup mashed ripe bananas about 3 medium
  • 0.5 cup granulated sugar
  • 0.25 cup light brown sugar packed
  • 0.33 cup unsalted butter, melted and cooled
  • 0.33 cup plain Greek yogurt or sour cream
  • 2 large eggs room temperature
  • 1.5 tsp vanilla extract
  • 1.5 cup all-purpose flour
  • 0.5 cup unsweetened cocoa powder natural or Dutch-process
  • 1 tsp baking soda
  • 0.75 tsp baking powder
  • 0.5 tsp fine sea salt
  • 0.5 tsp espresso powder optional, boosts chocolate flavor
  • 0.75 cup dark chocolate chips or chopped dark chocolate 60–70% cacao
  • 1 tbsp coarse sugar optional, for topping

Instructions

Preparation Steps

  • Preheat oven to 375°F. Line a 12-cup muffin pan with liners.
  • Whisk flour, cocoa, baking soda, baking powder, salt, and espresso powder in a bowl.
  • Mash bananas in a large bowl until mostly smooth.
  • Whisk in granulated sugar, brown sugar, melted butter, yogurt, eggs, and vanilla until combined.
  • Fold the dry ingredients into the banana mixture just until no dry streaks remain.
  • Stir in dark chocolate, keeping the batter thick and lumpy.
  • Divide batter among liners, filling each about 3/4 full. Sprinkle with coarse sugar if using.
  • Bake 16–18 minutes, until a toothpick comes out with a few moist crumbs (melted chocolate is fine).
  • Cool in the pan 5 minutes, then transfer muffins to a rack to finish cooling.

Notes

Variation: Swap half the dark chips with toasted walnuts for crunch. For extra lift, start at 400°F for 5 minutes, then finish baking at 350°F. Storage: Keep covered at room temperature 2–3 days or freeze up to 2 months.
