Equipment

  • Muffin Tin
  • Mixing Bowl

Ingredients

Dry Ingredients

  • 1.5 cups all-purpose flour
  • 1 teaspoon baking soda
  • 1 teaspoon baking powder
  • 0.5 teaspoon salt

Wet Ingredients

  • 3 bananas, peeled and mashed
  • 0.75 cup granulated sugar
  • 1 large egg, beaten
  • 0.33 cup unsalted butter, melted
  • 1 cup fresh blueberries

Crumb Topping (Optional)

  • 0.25 cup additional flour
  • 2 tablespoons granulated sugar
  • 2 tablespoons melted butter

Instructions

  • Preheat your oven to 350°F (175°C). Prepare a muffin tin by lining it with paper liners or greasing it lightly with non-stick spray.
  • In a medium bowl, whisk together the all-purpose flour, baking soda, baking powder, and salt until combined.
  • In a large bowl, mash the bananas until smooth. Add the granulated sugar and the beaten egg, mixing until well combined. Pour in the melted unsalted butter and stir until homogenous.
  • Slowly add the dry ingredients to the wet mixture, stirring gently. Be careful not to overmix; a few lumps are fine!
  • Gently fold in the fresh blueberries into the batter.
  • Spoon the muffin batter into the prepared muffin cups, filling each about two-thirds full.
  • In a small bowl, mix together the additional flour, granulated sugar, and melted butter until crumbly. Sprinkle the crumb topping over the muffins before baking.
  • Bake the muffins for 18-20 minutes, or until a toothpick inserted into the center comes out clean.
  • Allow the muffins to cool in the pan for about 5 minutes before transferring them to a wire rack to cool completely.

Notes

Use overripe bananas for maximum sweetness. Store leftovers in an airtight container for up to 3 days or freeze for longer storage.
