Ingredients

Scale
  • 1/2 cup (115g) unsalted butter, browned and cooled slightly
  • 3/4 cup (150g) granulated sugar
  • 1/4 cup (50g) brown sugar, packed
  • 2 large eggs, at 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 fresh zucchini (about 2 medium zucchinis), excess moisture squeezed out
  • 1/4 cup (60g) plain Greek yogurt or sour cream
  • For the Cinnamon Streusel Topping:
  • 1/3 cup (40g) all-purpose flour
  • 1/3 cup (65g) light brown sugar, packed
  • 1 teaspoon ground cinnamon
  • 3 tablespoons (43g) unsalted butter, cold and cubed
  • Pinch of salt

Instructions

  1. Brown the Butter: In a small saucepan over medium heat, melt the butter. Stir constantly as it foams and turns golden brown with a nutty aroma, about 5-7 minutes. Remove from heat and cool slightly for about 10 minutes.
  2. Grate and Prep Zucchini: Grate zucchini using the large holes of a box grater. Place grated zucchini in a clean kitchen towel or cheesecloth and squeeze out excess moisture.
  3. Mix Dry Ingredients: In a medium bowl, whisk together flour, baking soda, cinnamon, and salt. Set aside.
  4. Combine Sugars and Eggs: In a large bowl, whisk granulated and brown sugars with the slightly cooled brown butter until well combined. Add eggs one at a time, mixing until smooth. Stir in vanilla extract and Greek yogurt or sour cream.
  5. Fold in Dry Ingredients and Zucchini: Gradually add dry ingredients to wet ingredients, folding gently with a spatula just until combined. Fold in grated zucchini. Do not overmix.
  6. Prepare Cinnamon Streusel: In a small bowl, mix flour, brown sugar, cinnamon, and salt. Add cold cubed butter and rub between fingers until mixture resembles coarse crumbs.
  7. Assemble and Bake: Pour batter into greased 9×5 inch loaf pan. Evenly sprinkle streusel topping over batter. Bake at 350°F (175°C) for 50-60 minutes. Check doneness with a toothpick; it should come out clean or with a few moist crumbs.
  8. Cool: Let bread cool in pan for 15 minutes, then transfer to a cooling rack. Streusel will crisp as it cools.

Notes

Use firm zucchini and squeeze out excess moisture to avoid soggy bread. Brown butter carefully to avoid burning. Chill streusel mixture if warm to maintain crumbly texture. Baking time may vary by oven; tent with foil if streusel browns too quickly. Resting bread overnight improves flavor.
