Ingredients:

  • 1.5 cups (150g) grated zucchini
  • 0.5 cup (115g) melted unsalted butter
  • 0.75 cup (150g) granulated sugar
  • 1 large egg
  • 1 tsp (5ml) pure vanilla extract
  • 1.75 cups (220g) all-purpose flour
  • 1 tsp (5g) baking soda
  • 0.5 tsp (3g) baking powder
  • 0.5 tsp (3g) salt
  • 1 tsp (2g) ground cinnamon
  • 1 cup (170g) semi-sweet chocolate chips

Instructions:

  1. Preheat your oven to 425°F (218°C) and line a 12-cup muffin tin with paper liners or grease them thoroughly.
  2. Grate zucchini using the large holes of a box grater, leaving the skin on.
  3. In a medium bowl, whisk together the melted butter, sugar, egg, and vanilla until smooth, then stir in the grated zucchini.
  4. In a separate bowl, whisk together the flour, baking soda, baking powder, salt, and cinnamon.
  5. Gently pour the dry ingredients into the wet ingredients and fold with a spatula until just combined; stop while a few streaks of flour remain.
  6. Fold in the chocolate chips gently.
  7. Spoon the batter evenly into the 12 muffin cups, filling them nearly to the top.
  8. Bake at 425°F (218°C) for 5 minutes. Without opening the oven door, reduce the heat to 350°F (175°C) and bake for another 13-15 minutes.
  9. Test the center with a toothpick; it should come out clean or with a few moist crumbs.
