Ingredients

Scale
  • 3 medium ripe bananas, mashed
  • 6 tablespoons (85g) unsalted butter
  • 1 ½ cups (190g) all-purpose flour
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • ¾ cup (150g) brown sugar
  • 2 large eggs, room temperature
  • 1 teaspoon pure vanilla extract
  • ¾ cup (90g) toasted walnuts, roughly chopped

Instructions

  1. Brown the butter: Place 6 tablespoons (85g) of unsalted butter in a medium saucepan over medium heat. Stir frequently as it melts. Watch closely as the butter foams, then starts to turn golden and smell nutty (about 5–7 minutes). Remove from heat immediately to avoid burning. Pour into your mixing bowl and let cool slightly.
  2. Prep the bananas: While the butter cools, mash 3 medium ripe bananas with a fork until mostly smooth with some small lumps remaining. Add the mashed bananas to the browned butter in the bowl and stir gently to combine.
  3. Add sugar and eggs: Mix in ¾ cup (150g) brown sugar until incorporated. Then whisk in 2 large eggs, one at a time, followed by 1 teaspoon vanilla extract.
  4. Combine dry ingredients: In a separate small bowl, whisk together 1 ½ cups (190g) all-purpose flour, 1 teaspoon baking soda, and ½ teaspoon salt.
  5. Mix dry into wet: Gradually fold the dry ingredients into the wet banana mixture using a spatula. Be careful not to overmix — once the flour disappears, stop. The batter should be thick and slightly lumpy, not smooth or runny.
  6. Toast walnuts: In a dry skillet over medium heat, toast ¾ cup (90g) chopped walnuts for 4–5 minutes, stirring frequently until fragrant and slightly darkened. Let them cool briefly, then fold into the batter.
  7. Prepare the loaf pan: Lightly grease a 9×5-inch loaf pan with butter or non-stick spray. Pour the batter in and smooth the top with a spatula. Optionally, sprinkle a few walnuts on top for extra crunch.
  8. Bake: Bake at 350°F (175°C) for 55–65 minutes. Check doneness by inserting a toothpick in the center — it should come out with a few moist crumbs but no raw batter. Tent with foil if the top browns too quickly.
  9. Cool: Allow the bread to cool in the pan for 10 minutes, then transfer to a cooling rack to cool completely.

Notes

Brown the butter slowly and stir constantly to avoid burning. Do not overmix the batter to keep the bread moist and tender. Toast walnuts just before folding them into the batter for best flavor. Start checking the bread at 50 minutes as oven temperatures vary. Cool bread completely before slicing to avoid crumbling.
