Bake moist, flavorful peanut butter banana bread muffins perfect for a quick breakfast or snack using simple ingredients.

Ingredients

Scale
  • 1 3/4 cups all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1/2 cup (1 stick) unsalted butter, softened
  • 1/2 cup creamy peanut butter
  • 3/4 cup packed light brown sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1 cup mashed ripe bananas (about 3 medium)
  • 1/4 cup milk
  • 1/2 cup peanut butter chips (optional)

Instructions

  1. Preheat your oven to 375 degrees F. Line a 12-cup muffin tin with paper liners or grease well.
  2. In a medium bowl, whisk together the flour, baking soda, baking powder, and salt. Set this aside.
  3. In a large bowl, cream together the softened butter, peanut butter, and brown sugar until light and fluffy. This takes about 2 minutes.
  4. Beat in the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
  5. Add the mashed bananas and milk to the wet ingredients. Mix until just combined. Do not overmix.
  6. Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just incorporated. A few streaks of flour are acceptable.
  7. Fold in the peanut butter chips, if using.
  8. Divide the batter evenly among the 12 muffin cups, filling each about two-thirds full.
  9. Bake for 18 to 22 minutes, or until a toothpick inserted into the center comes out clean.
  10. Let the muffins cool in the pan for 5 minutes before transferring them to a wire rack to cool completely.

Notes

  • Use very ripe, spotty bananas for the best flavor and moisture in these banana bread inspired muffins.
  • For a healthier option, substitute half the all-purpose flour with whole wheat flour.
  • You can make this a simple muffin recipe peanut butter banana by skipping the chips.
  • Store cooled muffins in an airtight container at room temperature for up to 3 days.
