Ingredients

Scale
  • 1/2 cup (113g) unsalted butter, browned
  • 3 medium ripe bananas, mashed (about 1 1/2 cups)
  • 1 cup grated zucchini, packed and squeezed dry
  • 3/4 cup (150g) brown sugar
  • 2 large eggs, at room temperature
  • 1 teaspoon vanilla extract
  • 1 3/4 cups (220g) all-purpose flour, sifted
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 teaspoon cinnamon (optional)
  • 1/2 cup (60g) chopped walnuts, toasted

Instructions

  1. Brown the butter: Melt unsalted butter in a small saucepan over medium heat, stirring frequently until it foams and browns with a nutty aroma. Remove from heat and cool for about 5 minutes.
  2. Prepare zucchini: Grate zucchini finely and squeeze out excess moisture using a clean kitchen towel or cheesecloth.
  3. Mix wet ingredients: In a large bowl, mash bananas until smooth. Stir in brown sugar, then whisk in eggs and vanilla extract. Slowly add cooled brown butter and mix gently.
  4. Fold in grated zucchini evenly into the wet mixture.
  5. Combine dry ingredients: In another bowl, sift together flour, baking soda, salt, and cinnamon if using.
  6. Gradually fold dry ingredients into wet ingredients in two or three additions, mixing until just incorporated. Avoid overmixing.
  7. Fold in toasted walnuts, reserving some to sprinkle on top if desired.
  8. Prepare loaf pan: Grease a 9×5 inch loaf pan with butter or non-stick spray and lightly dust with flour. Pour batter into pan and smooth the top. Sprinkle remaining walnuts on top.
  9. Bake at 350°F (175°C) for 55-65 minutes. Check doneness at 50 minutes with a toothpick; it should come out with moist crumbs but no wet batter.
  10. Cool bread in pan for 15 minutes, then transfer to a wire rack to cool completely.

Notes

Brown the butter carefully to avoid bitterness; remove from heat as soon as brown specks appear and nutty aroma is detected. Squeeze zucchini thoroughly to prevent sogginess. Do not overmix batter to keep bread tender. Toast walnuts in a dry skillet over medium heat for about 5 minutes until fragrant.
