Ingredients

Scale
  • 3 medium ripe bananas, mashed
  • 1/2 cup (113g) unsalted butter, browned
  • 3/4 cup (150g) granulated sugar
  • 1/4 cup (50g) brown sugar
  • 2 large eggs, room temperature
  • 1 teaspoon vanilla extract
  • 1 3/4 cups (220g) all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1/2 cup (60g) chopped walnuts
  • 2 tablespoons brown sugar
  • 1/2 teaspoon ground cinnamon (optional)

Instructions

  1. Brown the butter: In a medium saucepan over medium heat, melt the unsalted butter. Stir frequently as it foams and turns golden brown with a nutty aroma. Once brown specks appear and the scent is toasted, remove from heat and pour into a large mixing bowl to cool slightly.
  2. Prepare the walnut crumble topping by combining chopped walnuts, brown sugar, and ground cinnamon in a small bowl. Set aside.
  3. Mix wet ingredients: To the cooled brown butter, add granulated sugar and brown sugar. Whisk until combined. Add eggs one at a time, beating well after each. Stir in vanilla extract. Fold in mashed bananas until uniform.
  4. In a separate bowl, whisk together flour, baking soda, and salt.
  5. Gently fold the dry ingredients into the wet mixture with a spatula until just combined. Avoid overmixing. The batter should be thick but pourable.
  6. Grease a 9×5-inch loaf pan or line with parchment paper. Pour batter into the pan and smooth the top.
  7. Sprinkle the walnut crumble topping evenly over the batter, pressing gently to adhere.
  8. Preheat oven to 350°F (175°C). Bake for 55 to 65 minutes, or until a toothpick inserted in the center comes out clean or with a few moist crumbs. Tent with foil if topping browns too quickly.
  9. Cool the bread in the pan for 10 minutes, then transfer to a cooling rack to cool completely before slicing.

Notes

Use a light-colored pan for browning butter to better monitor color changes. Avoid overmixing the batter to keep the bread tender. If topping browns too fast, tent with foil. Let bread cool completely before slicing to prevent crumbling. Bananas can be ripened faster by baking at 300°F for 15 minutes.
