Ingredients

Scale
  • 1/2 cup (115g) unsalted butter, browned and cooled slightly
  • 3/4 cup (150g) granulated sugar
  • 1/4 cup (50g) light brown sugar, packed
  • 2 large eggs, room temperature
  • 3 medium ripe bananas, mashed
  • 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, toasted
  • 1/4 cup (50g) brown sugar, packed
  • 1/2 teaspoon ground cinnamon
  • 2 tablespoons (28g) unsalted butter, melted

Instructions

  1. Brown the butter: Place 1/2 cup unsalted butter in a medium saucepan over medium heat. Stir constantly with a wooden spoon as it melts, foams, and turns golden brown with a nutty aroma. Remove from heat and cool slightly.
  2. Prepare the streusel topping: In a small bowl, combine 1/2 cup chopped walnuts, 1/4 cup packed brown sugar, 1/2 teaspoon ground cinnamon, and 2 tablespoons melted butter. Mix until crumbly and set aside.
  3. Mix wet ingredients: In a large bowl, whisk together browned butter, 3/4 cup granulated sugar, and 1/4 cup brown sugar until combined. Add eggs one at a time, whisking well after each. Stir in mashed bananas and vanilla extract until smooth.
  4. Combine dry ingredients: In a separate bowl, sift together flour, baking soda, and salt.
  5. Fold dry into wet: Gently fold dry ingredients into wet mixture using a rubber spatula until no flour streaks remain. Do not overmix.
  6. Pour batter into pan: Transfer batter to a greased or parchment-lined 9×5 inch loaf pan and smooth the top.
  7. Add streusel topping: Sprinkle walnut streusel evenly over batter, pressing lightly to adhere.
  8. Bake: Preheat oven to 350°F (175°C). Bake for 55 to 65 minutes or until a toothpick inserted in the center comes out mostly clean with a few moist crumbs. Tent with foil halfway through if topping browns too quickly.
  9. Cool completely: Cool bread in pan on a wire rack for 15 minutes, then remove from pan and cool another 15 minutes before slicing.

Notes

Watch the butter carefully when browning to avoid burning. Use ripe bananas with brown spots for maximum sweetness and moisture. Do not overmix the batter after adding flour to keep the bread tender. Tent with foil if streusel browns too quickly. For gluten-free, substitute flour with a 1:1 gluten-free blend. For dairy-free or vegan, use browned coconut oil and flax eggs.
