Ingredients

Scale
  • 1 ½ cups all-purpose flour (190 g)
  • 1 teaspoon baking soda
  • ½ teaspoon baking powder
  • ½ teaspoon salt
  • 1 teaspoon ground cinnamon
  • 2 large eggs, room temperature
  • ¾ cup granulated sugar (150 g)
  • ½ cup vegetable oil (120 ml)
  • 1 teaspoon pure vanilla extract
  • 1 ½ cups grated zucchini (about 1 medium zucchini)
  • 1 cup fresh blueberries (150 g)
  • For the Streusel Topping:
  • ½ cup all-purpose flour (65 g)
  • ⅓ cup brown sugar (70 g), packed
  • ¼ cup cold unsalted butter (57 g), cubed
  • ½ teaspoon ground cinnamon
  • Pinch of salt

Instructions

  1. Preheat your oven to 350°F (175°C). Grease your 9×5-inch loaf pan lightly with butter or nonstick spray.
  2. Prepare the streusel topping: In a small bowl, combine ½ cup flour, ⅓ cup brown sugar, ½ teaspoon cinnamon, and a pinch of salt. Cut in the cold butter until the mixture resembles coarse crumbs. Set aside in the fridge.
  3. Grate the zucchini using a box grater. Gently squeeze out excess moisture with a towel but keep some moisture for tenderness.
  4. Mix dry ingredients: In a large bowl, whisk together 1 ½ cups flour, baking soda, baking powder, salt, and 1 teaspoon cinnamon.
  5. Combine wet ingredients: In another bowl, beat 2 eggs with ¾ cup sugar until pale and smooth. Add vegetable oil and vanilla extract, mixing gently.
  6. Fold grated zucchini into wet ingredients. Gradually add dry ingredients, folding carefully until just combined.
  7. Gently fold in blueberries to avoid breaking skins.
  8. Transfer batter to the prepared loaf pan and smooth the top.
  9. Sprinkle streusel topping evenly over the batter without pressing down.
  10. Bake for 50-60 minutes or until a toothpick inserted comes out clean or with a few moist crumbs. Tent with foil if top browns too quickly.
  11. Cool bread in the pan for 15 minutes, then transfer to a wire rack to cool completely before slicing.

Notes

Do not overmix the batter to keep the bread tender. Keep some moisture in the zucchini for softness but avoid sogginess. Use cold butter for the streusel to maintain crunch. Toss blueberries in flour before folding to prevent sinking. Tent with foil if the streusel browns too fast.
