Ingredients

Scale
  • 3 to 4 ripe bananas, mashed
  • 1/2 cup (115g) unsalted butter, browned and cooled slightly
  • 3/4 cup (150g) granulated sugar
  • 1/4 cup (50g) light brown sugar
  • 2 large eggs, room temperature
  • 1 teaspoon pure vanilla extract
  • 1 1/2 cups (190g) all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon fine sea salt
  • 1/2 teaspoon ground cinnamon (optional)
  • For the streusel:
  • 1/2 cup (60g) chopped walnuts, toasted lightly
  • 1/4 cup (50g) light brown sugar
  • 2 tablespoons (28g) unsalted butter, melted
  • 1/4 cup (30g) all-purpose flour
  • 1/4 teaspoon ground cinnamon
  • A pinch of salt

Instructions

  1. Brown the butter: In a small saucepan over medium heat, melt 1/2 cup unsalted butter. Stir constantly as it foams and turns golden brown with a nutty aroma, about 5-7 minutes. Remove from heat and let cool slightly.
  2. Prepare the streusel: Combine chopped walnuts, brown sugar, flour, melted butter, cinnamon, and salt in a small bowl. Mix until crumbly but sticky enough to form clusters. Set aside.
  3. Mix wet ingredients: In a large bowl, mash bananas until smooth but slightly chunky. Stir in browned butter, granulated sugar, brown sugar, eggs, and vanilla extract until combined.
  4. Combine dry ingredients: In a medium bowl, whisk together flour, baking soda, salt, and cinnamon (if using).
  5. Fold dry into wet: Gently fold dry ingredients into wet banana mixture using a rubber spatula. Stop mixing as soon as flour disappears.
  6. Prepare pan: Grease a 9×5-inch loaf pan or line with parchment paper. Pour batter into pan and smooth the top.
  7. Add streusel topping: Sprinkle walnut streusel evenly over batter, pressing lightly to help it stick.
  8. Bake: Bake at 350°F (175°C) for 55-65 minutes. Check at 55 minutes with a toothpick; it should come out with a few moist crumbs but no wet batter. Tent with foil if streusel browns too fast.
  9. Cool and serve: Let bread cool in pan for 15 minutes, then transfer to wire rack to cool completely before slicing.

Notes

Brown butter carefully to avoid burning; stir constantly and watch for golden flecks and nutty aroma. Do not overmix batter to keep bread tender. Toast walnuts for extra crunch. Tent with foil if streusel browns too quickly. Let bread cool completely before slicing to set crumb.
