This easy one bowl banana bread with walnuts comes together in one bowl with simple ingredients. It’s moist, tender, and packed with toasty walnut crunch—perfect for using up overripe bananas.

Ingredients

Scale
  • 3 ripe bananas, mashed (about 1 ½ cups)
  • ⅓ cup melted butter (75g), unsalted
  • ¾ cup granulated sugar (150g)
  • 1 large egg, room temperature
  • 1 teaspoon vanilla extract
  • 1 ½ cups all-purpose flour (190g)
  • 1 teaspoon baking soda
  • ¼ teaspoon salt
  • ½ cup chopped walnuts (60g)

Instructions

  1. Preheat your oven to 350°F (175°C). Grease a 9×5-inch loaf pan with butter or nonstick spray. If using parchment paper, leave an overhang on the long sides for easy lifting.
  2. In your large mixing bowl, mash the three ripe bananas with a fork until mostly smooth. Leave a few small lumps for texture.
  3. Add the melted butter, sugar, egg, and vanilla extract. Stir together with the same fork until well combined.
  4. Sprinkle the flour, baking soda, and salt over the wet mixture. Stir gently until just combined. A few streaks of flour are okay. Do not overmix.
  5. Gently fold in the chopped walnuts until evenly distributed. Reserve a handful to sprinkle on top if desired.
  6. Pour the batter into the prepared pan and spread evenly. Sprinkle reserved walnuts on top if using.
  7. Bake for 55-65 minutes, until a toothpick inserted into the center comes out clean or with a few moist crumbs. If the top browns too quickly, tent loosely with foil after 40 minutes.
  8. Cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before slicing.

Notes

Toast walnuts before adding for extra flavor. Use very ripe bananas for best sweetness. Do not overmix the batter. Let bread cool completely before slicing to avoid crumbling. For a prettier loaf, reserve some walnuts to sprinkle on top before baking.
