Ingredients

Scale
  • 3 medium ripe bananas (about 1 1/2 cups mashed)
  • 1/2 cup (115g) unsalted butter, browned
  • 3/4 cup (150g) granulated sugar
  • 1/4 cup (50g) brown sugar
  • 2 large eggs, room temperature
  • 1 teaspoon pure vanilla extract
  • 1 3/4 cups (220g) all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 3/4 cup (75g) chopped walnuts
  • 2 tablespoons light brown sugar (for streusel)
  • 1/2 teaspoon ground cinnamon (optional for streusel)

Instructions

  1. Brown the butter: In a medium saucepan over medium heat, melt 1/2 cup (115g) of unsalted butter. Stir frequently as it foams and turns golden brown with a nutty aroma, about 5-7 minutes. Watch closely to avoid burning. Remove from heat and let cool for 5 minutes.
  2. Preheat your oven to 350°F (175°C). Grease and line a 9×5-inch loaf pan with parchment paper, leaving overhang for easy removal.
  3. Prepare the streusel: In a small bowl, mix 3/4 cup (75g) chopped walnuts, 2 tablespoons brown sugar, and 1/2 teaspoon ground cinnamon. Set aside.
  4. Mash the bananas: In a large bowl, mash 3 medium ripe bananas until smooth but still a little chunky (about 1 1/2 cups).
  5. Mix wet ingredients: To the mashed bananas, add the browned butter (cooled slightly), 3/4 cup (150g) granulated sugar, 1/4 cup (50g) brown sugar, 2 large eggs (room temp), and 1 teaspoon vanilla extract. Mix gently until combined.
  6. Combine dry ingredients: In a separate bowl, whisk together 1 3/4 cups (220g) all-purpose flour, 1 teaspoon baking soda, and 1/2 teaspoon salt.
  7. Fold dry into wet: Add the flour mixture to the wet ingredients in batches, folding gently with a rubber spatula. Avoid overmixing to keep the bread tender. Optionally, fold in a handful of chopped walnuts for extra nuttiness.
  8. Pour batter into pan: Transfer the batter to your prepared loaf pan and smooth the top. Evenly sprinkle the walnut streusel over the surface.
  9. Bake: Place the pan in the preheated oven and bake for 55-65 minutes. Start checking at 55 minutes by inserting a toothpick into the center; it should come out with a few moist crumbs but no wet batter. If the streusel browns too fast, loosely cover the bread with foil halfway through baking.
  10. Cool and enjoy: Let the bread cool in the pan for 15 minutes before lifting out with the parchment paper. Cool completely on a wire rack before slicing.

Notes

Watch the brown butter closely to avoid burning; stir constantly and remove from heat as soon as it smells nutty and has a deep amber color. Use folding technique to mix batter to avoid tough bread. If streusel browns too quickly, cover loosely with foil halfway through baking. For gluten-free, substitute flour with a gluten-free blend and add xanthan gum if needed. For vegan, use vegan butter and flax eggs.
