Ingredients

Scale
  • 6 tablespoons unsalted butter (for browning)
  • 3/4 cup granulated sugar
  • 1/4 cup packed brown sugar
  • 2 large eggs, room temperature
  • 1 teaspoon vanilla extract
  • 1 3/4 cups (220g) all-purpose flour
  • 1 teaspoon baking soda
  • 1 teaspoon ground cinnamon
  • 1/2 teaspoon salt
  • 1 1/2 cups grated zucchini (about 2 medium zucchinis)
  • 1/2 cup chopped walnuts (half for batter, half for streusel)
  • For the streusel:
  • 1/4 cup brown sugar
  • 2 tablespoons all-purpose flour
  • 2 tablespoons cold unsalted butter, cubed
  • 1/4 cup chopped walnuts

Instructions

  1. Brown the butter: Place 6 tablespoons of unsalted butter in a medium skillet over medium heat. Stir frequently as it melts and starts bubbling. After about 5 minutes, it will turn a golden brown with a nutty aroma. Remove from heat and let cool slightly.
  2. Preheat the oven to 350°F (175°C). Grease or line a 9×5 inch loaf pan with parchment paper.
  3. Grate zucchini using a box grater. No need to squeeze out moisture unless zucchini is very watery.
  4. In a large bowl, whisk together flour, baking soda, cinnamon, and salt.
  5. In another bowl, whisk granulated sugar, brown sugar, and eggs until smooth. Stir in the browned butter and vanilla extract.
  6. Slowly add dry ingredients to wet mixture, folding gently with a rubber spatula until just combined. Avoid overmixing.
  7. Fold in grated zucchini and 1/4 cup chopped walnuts evenly.
  8. Prepare streusel topping by mixing brown sugar, flour, and chopped walnuts in a small bowl. Cut in cold cubed butter until crumbly.
  9. Pour batter into prepared loaf pan and sprinkle streusel topping evenly over the batter.
  10. Bake for 50-60 minutes or until a toothpick inserted in the center comes out clean. Tent with foil if streusel browns too quickly.
  11. Cool bread in the pan for 15 minutes, then transfer to a wire rack to cool completely before slicing.

Notes

Brown the butter carefully to avoid burning; look for a golden brown color and nutty aroma. Do not overmix the batter to keep the bread tender. Use cold butter for the streusel to achieve a crumbly texture. If zucchini is watery, squeeze out excess moisture to prevent sogginess. Tent bread with foil if streusel browns too fast.
