Ingredients

Scale
  • 1/2 cup (1 stick, 113g) unsalted butter, browned
  • 3 ripe bananas, mashed
  • 1 cup shredded zucchini, squeezed dry
  • 3/4 cup granulated sugar
  • 1/4 cup packed brown sugar
  • 2 large eggs, room temperature
  • 1 tsp vanilla extract
  • 1 3/4 cups (220g) all-purpose flour
  • 1 tsp baking soda
  • 1/2 tsp salt
  • 1 tsp ground cinnamon
  • 1/2 cup chopped walnuts
  • Walnut streusel topping:
  • 1/4 cup brown sugar
  • 2 tbsp all-purpose flour
  • 2 tbsp cold unsalted butter, cubed
  • 1/4 cup chopped walnuts
  • 1/2 tsp cinnamon

Instructions

  1. Brown the Butter: In a medium saucepan over medium heat, melt 1/2 cup (113g) unsalted butter. Stir as it foams and browns, about 5-7 minutes, until nutty and deep amber. Remove from heat and cool slightly.
  2. Prepare Zucchini: Shred 1 cup zucchini using a box grater or food processor. Place shredded zucchini in a clean kitchen towel and squeeze out excess moisture.
  3. Mix Wet Ingredients: In a large bowl, combine mashed bananas and browned butter. Add 3/4 cup granulated sugar and 1/4 cup packed brown sugar, stirring until combined. Beat in 2 large eggs and 1 tsp vanilla extract until smooth.
  4. Combine Dry Ingredients: In a separate bowl, whisk together 1 3/4 cups all-purpose flour, 1 tsp baking soda, 1/2 tsp salt, and 1 tsp ground cinnamon.
  5. Combine Wet and Dry: Gradually fold dry ingredients into wet mixture gently. Fold in shredded zucchini and 1/2 cup chopped walnuts.
  6. Prepare Walnut Streusel: In a small bowl, mix 1/4 cup brown sugar, 2 tbsp flour, 1/2 tsp cinnamon, and 1/4 cup chopped walnuts. Cut in 2 tbsp cold cubed butter until mixture resembles coarse crumbs.
  7. Assemble and Bake: Pour batter into greased 9×5-inch loaf pan. Sprinkle walnut streusel evenly on top. Bake at 350°F (175°C) for 55-65 minutes or until toothpick inserted comes out clean. Tent with foil if top browns too fast.
  8. Cool: Let bread cool in pan for 15 minutes, then transfer to cooling rack to cool completely.

Notes

Use ripe bananas with brown spots for best sweetness. Squeeze excess moisture from zucchini to avoid soggy bread. Brown butter carefully to avoid burning. Tent bread with foil if top browns too quickly. For gluten-free, substitute flour with 1:1 gluten-free blend. For dairy-free, use coconut oil instead of butter but flavor will differ.
