Print Recipe

A moist and tender banana bread with rich ribbons of creamy peanut butter swirled throughout, perfect for breakfast or a snack.

Ingredients

Scale
  • 3 medium ripe bananas, mashed
  • 1 ½ cups all-purpose flour (190g)
  • 1 teaspoon baking soda
  • ¼ teaspoon salt
  • ½ cup unsalted butter (113g), softened
  • ¾ cup granulated sugar (150g)
  • 2 large eggs, room temperature
  • 1 teaspoon pure vanilla extract
  • ½ cup creamy peanut butter (125g)
  • Optional: ½ cup chopped walnuts or chocolate chips (60g)

Instructions

  1. Preheat oven to 350°F (175°C). Grease a 9×5-inch loaf pan with butter or non-stick spray and line with parchment paper if desired.
  2. In a medium bowl, whisk together the flour, baking soda, and salt. Set aside.
  3. In a large bowl, cream the softened butter and granulated sugar using an electric mixer or whisk by hand for 2-3 minutes until light and fluffy.
  4. Add the eggs one at a time to the butter-sugar mixture, beating well after each addition. Stir in the vanilla extract.
  5. Fold in the mashed bananas gently until just combined.
  6. Gradually add the dry ingredients to the wet mixture, folding carefully with a spatula until just combined. Fold in walnuts or chocolate chips if using.
  7. Transfer about two-thirds of the batter into the prepared loaf pan and smooth the surface.
  8. Warm the peanut butter slightly in the microwave (15-20 seconds) to make it more spreadable. Dollop it over the batter in spoonfuls.
  9. Drop the remaining batter on top of the peanut butter dollops. Use a butter knife or skewer to swirl the peanut butter through the batter in a figure-eight motion, creating visible ribbons without fully mixing.
  10. Bake for 55-65 minutes, until a toothpick inserted in the center comes out with a few moist crumbs but no raw batter. Tent with foil if the top browns too quickly.
  11. Let the bread cool in the pan for 15 minutes, then transfer to a cooling rack to cool completely before slicing.

Notes

Use very ripe bananas for natural sweetness and moisture. Do not overmix the batter to avoid toughness. Warm peanut butter slightly for easier swirling. Tent with foil if top browns too fast. Let bread cool completely before slicing to set the swirl pattern. Variations include adding cocoa powder for chocolate swirl, using almond flour for gluten-free, or flax eggs and coconut oil for vegan adaptation.
