A quick and easy one-bowl banana bread recipe featuring ripe bananas and a caramelized brown sugar walnut crunch topping. Moist, flavorful, and perfect for any occasion.

Ingredients

Scale
  • 3 medium ripe bananas, mashed
  • 1 ½ cups (190 g) all-purpose flour
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • ½ cup (115 g) unsalted butter, melted and slightly cooled
  • ¾ cup (150 g) packed light brown sugar for batter
  • ¼ cup (50 g) packed light brown sugar for walnut crunch topping
  • 2 large eggs, room temperature
  • 1 teaspoon vanilla extract
  • ½ cup (60 g) chopped walnuts, toasted
  • Additional chopped walnuts for topping
  • Optional: chocolate chips or cinnamon

Instructions

  1. Preheat your oven to 350°F (175°C). Grease and flour a 9×5 inch loaf pan or line it with parchment paper.
  2. Mash the bananas in a large mixing bowl using a fork or potato masher until mostly smooth with some small lumps remaining.
  3. Add melted butter and ¾ cup brown sugar to the mashed bananas. Stir gently until combined.
  4. Whisk in the eggs one at a time, then add vanilla extract. Mix gently until well incorporated.
  5. In a separate bowl, combine flour, baking soda, and salt.
  6. Gradually fold the dry ingredients into the wet mixture using a wooden spoon or spatula. Avoid overmixing.
  7. Fold in the toasted chopped walnuts, reserving a small handful for topping.
  8. Transfer the batter to the prepared loaf pan and smooth the top.
  9. Mix the reserved walnuts with ¼ cup brown sugar and sprinkle evenly over the batter.
  10. Bake for 55-65 minutes or until a toothpick inserted in the center comes out clean or with a few moist crumbs. Tent with foil if the top browns too quickly.
  11. Cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before slicing.

Notes

Avoid overmixing the batter to prevent a dense, rubbery texture. Use ripe bananas for natural sweetness and moisture. Toast walnuts carefully to avoid burning. Let the bread cool completely before slicing for best texture. For a moister loaf, add a tablespoon of sour cream or Greek yogurt to the wet ingredients. Can be made gluten-free or vegan with substitutions.
