Ingredients

Scale
  • 1 ½ cups (180g) all-purpose flour (or almond flour for gluten-free option)
  • 1 teaspoon baking powder
  • ½ teaspoon baking soda
  • ½ teaspoon salt
  • 1 teaspoon ground cinnamon
  • 2 large eggs, room temperature
  • ½ cup (100g) granulated sugar
  • ¼ cup (50g) brown sugar, packed
  • ⅓ cup (80ml) vegetable oil or melted coconut oil
  • 1 teaspoon vanilla extract
  • 1 ½ cups (150g) finely shredded zucchini, squeezed dry
  • ¾ cup (130g) semi-sweet chocolate chips
  • For the streusel topping:
  • ½ cup (60g) all-purpose flour
  • ⅓ cup (65g) brown sugar, packed
  • ¼ cup (56g) cold unsalted butter, cubed
  • ½ teaspoon ground cinnamon
  • Pinch of salt

Instructions

  1. Preheat your oven to 350°F (175°C). Line a 12-cup muffin tin with liners or grease well.
  2. Shred 1 ½ cups of zucchini using a box grater or food processor. Squeeze firmly to remove excess moisture.
  3. In a large bowl, whisk together flour, baking powder, baking soda, salt, and cinnamon.
  4. In another bowl, beat eggs with granulated sugar and brown sugar until smooth and slightly fluffy. Add vegetable oil and vanilla extract, mixing until combined.
  5. Stir shredded zucchini into the wet mixture. Gently fold in the dry ingredients until just combined. Fold in chocolate chips last.
  6. In a small bowl, combine flour, brown sugar, cinnamon, and salt for the streusel. Cut in cold butter until mixture resembles coarse crumbs.
  7. Spoon batter evenly into muffin cups, filling about two-thirds full. Sprinkle streusel generously over each muffin.
  8. Bake for 22–25 minutes or until a toothpick inserted comes out clean or with a few crumbs. Tops should be golden brown and streusel crisp.
  9. Let muffins cool in the tin for 5 minutes, then transfer to a wire rack to cool completely.

Notes

Squeeze zucchini well to avoid soggy muffins. Do not overmix batter to keep muffins tender. Use cold butter for streusel and chill if kitchen is warm. Batter can rest in fridge for a few hours before baking. Tent muffins with foil if streusel browns too fast.
