Ingredients

Scale
  • 1 ½ cups all-purpose flour (190g)
  • 1 teaspoon baking soda
  • ½ teaspoon baking powder
  • ¾ teaspoon ground cinnamon
  • ½ teaspoon salt
  • 2 large ripe bananas, mashed (about 1 cup)
  • 1 cup grated zucchini (about 1 medium zucchini), squeezed dry
  • ½ cup granulated sugar
  • ¼ cup brown sugar, packed
  • ⅓ cup vegetable oil or melted coconut oil
  • 2 large eggs, room temperature
  • 1 teaspoon pure vanilla extract
  • ½ cup chopped walnuts (toasted if desired)
  • ¼ cup brown sugar, packed (for streusel)
  • 2 tablespoons all-purpose flour (for streusel)
  • 1 teaspoon ground cinnamon (for streusel)
  • 3 tablespoons cold unsalted butter, cubed (for streusel)

Instructions

  1. Wash and dry a medium zucchini. Grate it using a box grater or food processor. Place the shredded zucchini in a clean kitchen towel and squeeze out as much moisture as possible. Set aside.
  2. Preheat oven to 350°F (175°C). Grease a 9×5 inch loaf pan with butter or line with parchment paper.
  3. In a medium bowl, sift together flour, baking soda, baking powder, cinnamon, and salt. Whisk to combine.
  4. In a large bowl, mash the ripe bananas until smooth. Add granulated sugar, brown sugar, oil, eggs, and vanilla extract. Whisk until smooth and slightly thickened.
  5. Fold the grated zucchini gently into the wet mixture, then gradually add the dry ingredients. Stir just until combined; do not overmix.
  6. In a small bowl, combine chopped walnuts, brown sugar, flour, and cinnamon. Add cold cubed butter and use a pastry cutter or fingers to mix until the topping resembles coarse crumbs.
  7. Pour the batter into the prepared loaf pan and spread evenly. Sprinkle the walnut streusel topping generously over the batter.
  8. Bake for 50-55 minutes, or until a toothpick inserted near the center comes out clean. If the topping browns too quickly, tent the pan loosely with foil after 40 minutes.
  9. Let the bread cool in the pan for 15 minutes, then turn out onto a wire rack to cool completely.

Notes

Squeeze zucchini well to avoid sogginess. Use cold butter for streusel to get crumbly texture. Tent with foil if topping browns too fast. Let bread cool completely before slicing for best texture. Bananas can be ripened in a 300°F oven for 10-15 minutes if needed.
