Ingredients

Scale
  • 1 ½ cups (188g) all-purpose flour
  • ½ cup (100g) granulated sugar
  • ¼ cup (50g) light brown sugar, packed
  • 1 teaspoon baking soda
  • ½ teaspoon baking powder
  • 1 ½ teaspoons ground cinnamon
  • ½ teaspoon salt
  • 1 ½ cups (about 1 medium zucchini, 180g) shredded zucchini
  • 2 large eggs, at room temperature
  • ½ cup (120ml) vegetable oil
  • ¼ cup (60g) Greek yogurt
  • 1 teaspoon vanilla extract
  • ½ cup (63g) all-purpose flour (for streusel)
  • ¼ cup (50g) light brown sugar, packed (for streusel)
  • 1 teaspoon ground cinnamon (for streusel)
  • 3 tablespoons (42g) unsalted butter, cold and cubed (for streusel)

Instructions

  1. Preheat oven to 350°F (175°C). Line a 12-cup muffin tin with paper liners or grease well.
  2. Shred the zucchini using a box grater. Place in a clean kitchen towel or paper towels and squeeze out excess moisture. Set aside.
  3. Make the streusel: In a small bowl, combine ½ cup flour, ¼ cup packed brown sugar, and 1 teaspoon cinnamon. Add cold cubed butter and cut in with a pastry cutter or your fingers until mixture resembles coarse crumbs. Refrigerate until needed.
  4. In a large bowl, whisk together 1 ½ cups flour, ½ cup granulated sugar, ¼ cup packed brown sugar, 1 teaspoon baking soda, ½ teaspoon baking powder, 1 ½ teaspoons cinnamon, and ½ teaspoon salt.
  5. In a medium bowl, whisk together eggs, vegetable oil, Greek yogurt, and vanilla extract until smooth and slightly pale.
  6. Pour wet ingredients into dry ingredients and fold gently with a spatula until just combined. Do not overmix.
  7. Fold in the shredded zucchini until evenly distributed.
  8. Divide batter evenly among the 12 muffin cups, filling each about ¾ full.
  9. Remove streusel from fridge and sprinkle generously over each muffin, pressing down lightly.
  10. Bake for 18-22 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs.
  11. Let muffins cool in the tin for 5 minutes, then transfer to a wire rack to cool completely.

Notes

Squeezing excess moisture from the zucchini is crucial to avoid soggy muffins. Keep the streusel cold for a crunchier topping. Room temperature eggs help the batter come together smoothly. Measure flour by spooning into the cup and leveling off. Rotate the pan halfway through baking for even browning.
