This Perfect One Bowl Walnut Banana Bread is a simple, forgiving recipe that delivers a moist, tender loaf with a nutty crunch. It’s the ultimate comfort food with minimal cleanup.

Ingredients

Scale
  • 3 medium ripe bananas (about 1 ½ cups mashed)
  • ¾ cup granulated sugar (150g)
  • ⅓ cup vegetable oil (80ml)
  • 1 large egg, room temperature
  • 1 teaspoon vanilla extract
  • 1 ½ cups all-purpose flour (190g)
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • 1 teaspoon ground cinnamon
  • ½ cup chopped walnuts (60g), toasted

Instructions

  1. Preheat oven to 350°F (175°C). Line a 9×5-inch loaf pan with parchment paper, leaving overhang on the long sides. Lightly grease exposed ends.
  2. In a large mixing bowl, mash the bananas with a fork until mostly smooth with a few small lumps (about 1 ½ cups).
  3. Add sugar, oil, egg, and vanilla extract to the mashed bananas. Whisk until smooth and well combined.
  4. Add flour, baking soda, salt, and cinnamon to the bowl. Fold gently with a rubber spatula until just combined (a few lumps are okay).
  5. Fold in the toasted walnuts, reserving a handful for topping if desired.
  6. Pour batter into the prepared loaf pan and spread evenly. Sprinkle reserved walnuts on top and gently press them in.
  7. Bake for 50-60 minutes, until a toothpick inserted in the center comes out clean or with a few moist crumbs. If browning too quickly, tent with foil after 40 minutes.
  8. Cool in the pan on a wire rack for 10 minutes, then lift out using the parchment sling and cool completely on the rack.

Notes

Don’t overmix the batter once flour is added to avoid a tough loaf. Toast walnuts for best flavor and crunch. Use room temperature egg for better emulsion. For accurate flour measurement, use a kitchen scale (190g) or spoon and level the flour.
