Ingredients

Scale
  • 2 cups all-purpose flour (250 g)
  • 2 teaspoons baking powder
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 teaspoon ground cinnamon
  • 3/4 cup granulated sugar (150 g)
  • 1/3 cup vegetable oil (80 ml)
  • 2 large eggs, room temperature
  • 1 teaspoon vanilla extract
  • 1 1/2 cups grated zucchini, squeezed dry
  • 1 cup semi-sweet chocolate chips (175 g)
  • Cinnamon sugar topping: 2 tablespoons granulated sugar mixed with 1 teaspoon ground cinnamon

Instructions

  1. Preheat your oven to 350°F (175°C). Grease a 12-cup muffin tin or line it with paper liners.
  2. Grate the zucchini using a box grater into a clean towel or cheesecloth. Squeeze out as much excess liquid as possible.
  3. In a mixing bowl, combine the all-purpose flour, baking powder, baking soda, salt, and ground cinnamon. Whisk together for about 30 seconds.
  4. Add the granulated sugar to the dry mix and stir again.
  5. Add the vegetable oil, eggs, and vanilla extract to the same bowl. Mix gently with a spatula or wooden spoon until just combined; do not overmix.
  6. Fold in the grated zucchini and chocolate chips carefully, about 1-2 minutes. If the batter looks too dry, add up to 1/4 cup (60 ml) milk.
  7. Spoon the batter into the muffin cups, filling each about 3/4 full. Sprinkle the cinnamon sugar topping evenly over each muffin.
  8. Bake for 20-25 minutes, or until a toothpick inserted in the center comes out clean or with a few moist crumbs. Start checking at 18 minutes.
  9. Cool the muffins in the tin for 5 minutes, then transfer to a wire rack to cool completely.

Notes

Do not overmix the batter to avoid tough muffins. Thoroughly squeeze out excess moisture from zucchini to prevent soggy muffins. Use room temperature eggs for better mixing. If muffins brown too fast, tent with foil after 15 minutes. Variations include gluten-free flour, vegan substitutions, adding nuts or berries, or baking as a loaf.
