Ingredients

Scale
  • 34 ripe bananas, mashed
  • 6 tablespoons unsalted butter, browned and cooled slightly
  • 3/4 cup granulated sugar
  • 1/4 cup brown sugar
  • 2 large eggs, at room temperature
  • 1 teaspoon vanilla extract
  • 1 3/4 cups all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 3/4 cup walnuts, chopped
  • 1/4 cup brown sugar (for topping)
  • 1/2 teaspoon cinnamon (optional, for streusel topping)

Instructions

  1. Brown the butter: Place 6 tablespoons of unsalted butter in a medium saucepan over medium heat. Stir frequently as it melts, then starts to foam and turn golden brown with toasted nutty bits at the bottom. Remove from heat immediately once you smell a deep caramel aroma and see amber color. Pour into a heat-safe bowl and let cool for 5 minutes.
  2. Preheat oven to 350°F (175°C). Grease a 9×5 inch loaf pan or line it with parchment paper.
  3. Mix wet ingredients: In a large bowl, mash 3-4 ripe bananas with a fork until smooth but slightly chunky. Add browned butter, 3/4 cup granulated sugar, 1/4 cup brown sugar, 2 large eggs, and 1 teaspoon vanilla extract. Stir gently until combined and glossy.
  4. Combine dry ingredients: In a separate bowl, whisk 1 3/4 cups all-purpose flour, 1 teaspoon baking soda, 1/2 teaspoon salt, and optionally 1/2 teaspoon cinnamon.
  5. Incorporate dry into wet: Add dry ingredients to wet mixture in two parts, folding gently after each addition. Avoid overmixing; batter should be thick and a little lumpy. Optionally fold in a handful of chopped walnuts for extra crunch inside.
  6. Prepare streusel topping: Mix 3/4 cup chopped walnuts, 1/4 cup brown sugar, and 1/2 teaspoon cinnamon in a small bowl.
  7. Pour batter into prepared loaf pan and smooth the top. Sprinkle walnut streusel evenly over the surface.
  8. Bake for 50-60 minutes. Check doneness after 50 minutes by inserting a toothpick in the center; it should come out clean or with moist crumbs. If topping browns too fast, loosely cover with foil for last 10 minutes.
  9. Cool and rest: Let bread cool in the pan on a rack for 15 minutes before removing. This helps the bread set and makes slicing easier.

Notes

Use a light-colored pan to brown butter to watch color changes closely and avoid burning. Let browned butter cool before mixing to prevent cooking eggs prematurely. Avoid overmixing batter to keep bread tender. Tent with foil if topping browns too quickly. Let bread cool 15 minutes before slicing for best texture. For gluten-free, substitute flour with gluten-free blend and add xanthan gum if needed. For vegan, use flax eggs and coconut oil browned carefully.
