Ingredients

Scale
  • 1/2 cup (115g) unsalted butter (for browning)
  • 2 cups (240g) all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1 teaspoon ground cinnamon
  • 1/2 teaspoon freshly grated nutmeg (optional)
  • 1 cup (200g) granulated sugar
  • 1/2 cup (100g) light brown sugar, packed
  • 2 large eggs, room temperature
  • 1 teaspoon vanilla extract
  • 1 1/2 cups (about 180g) grated zucchini, squeezed dry
  • 1/2 cup (120ml) plain Greek yogurt or sour cream
  • For the Walnut Streusel Topping:
  • 1/2 cup (60g) walnuts, chopped
  • 1/4 cup (50g) brown sugar
  • 2 tablespoons all-purpose flour
  • 2 tablespoons unsalted butter, cold and diced
  • 1/2 teaspoon ground cinnamon

Instructions

  1. Melt the 1/2 cup unsalted butter in a medium saucepan over medium heat. Stir frequently as it foams and then starts to brown, releasing a nutty aroma. When it turns a deep golden brown with tiny brown specks, remove from heat and pour into a heatproof bowl to cool slightly.
  2. Grate the zucchini using a box grater or food processor. Place the grated zucchini in a clean kitchen towel and squeeze firmly to remove excess moisture.
  3. In a large bowl, whisk together the flour, baking soda, baking powder, salt, cinnamon, and nutmeg. Set aside.
  4. In another bowl, whisk the granulated sugar, brown sugar, and eggs until combined and slightly fluffy. Stir in the vanilla extract. Then slowly mix in the cooled brown butter until fully incorporated.
  5. Stir in the Greek yogurt and grated zucchini to the wet mixture until evenly combined.
  6. Gradually fold the dry ingredients into the wet mixture using a rubber spatula. Stop when no flour streaks remain; do not overmix.
  7. In a small bowl, mix the chopped walnuts, brown sugar, flour, and cinnamon. Add the cold diced butter and use your fingers or a pastry cutter to rub it into the dry ingredients until the mixture looks crumbly and clumps together.
  8. Preheat oven to 350°F (175°C). Grease and flour a 9×5 inch loaf pan or line it with parchment paper. Pour the batter into the pan and spread evenly. Sprinkle the walnut streusel evenly over the top.
  9. Bake for 50-60 minutes, or until a toothpick inserted in the center comes out clean. If the streusel browns too fast, tent loosely with foil halfway through baking.
  10. Let the bread cool in the pan for 15 minutes, then transfer to a wire rack to cool completely.

Notes

Use a light-colored pan to brown butter to monitor color changes. Squeeze zucchini dry to avoid soggy bread. Fold batter gently to keep bread tender. Use cold butter for streusel to maintain crumbly texture. Tent with foil if streusel browns too quickly.
