Make incredibly moist, fluffy banana chocolate chip muffins using a simple, one-bowl method. This recipe is perfect for a quick breakfast or satisfying snack.

Ingredients

Scale
  • 3 large, very ripe bananas, mashed
  • 1/2 cup granulated sugar
  • 1/4 cup packed brown sugar
  • 2 large eggs, room temperature
  • 1/2 cup vegetable oil or melted butter
  • 1/2 cup sour cream or Greek yogurt
  • 1 teaspoon vanilla extract
  • 2 cups all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 cup semi-sweet chocolate chips

Instructions

  1. Preheat your oven to 400 degrees F. Line a 12-cup muffin tin with paper liners or grease well.
  2. In a large bowl, combine the mashed bananas, granulated sugar, and brown sugar. Mix until just combined.
  3. Add the eggs, oil, sour cream (or Greek yogurt), and vanilla extract to the banana mixture. Whisk until smooth.
  4. In a separate small bowl, whisk together the flour, baking soda, and salt.
  5. Add the dry ingredients to the wet ingredients. Mix with a spatula only until the flour streaks disappear. Do not overmix; a few lumps are fine.
  6. Gently fold in the chocolate chips.
  7. Divide the batter evenly among the 12 prepared muffin cups, filling each about two-thirds full.
  8. Bake for 18 to 22 minutes, or until a toothpick inserted into the center of a muffin comes out clean.
  9. Let the muffins cool in the pan for 5 minutes before transferring them to a wire rack to cool completely.

Notes

  • Using very ripe, spotty bananas provides the best natural sweetness and moisture for these banana muffins.
  • For bakery-style tall tops, fill the muffin cups almost to the top and start baking at a higher temperature (400°F) for the first 5 minutes before reducing the heat to 350°F for the remainder of the bake time.
  • You can substitute walnuts or pecans for the chocolate chips to make banana nut muffins.
