Ingredients

Scale
  • 1 cup finely grated zucchini (130 g)

  • 1 1/2 cups (187.5 g) all-purpose flour

  • 1/2 cup (40 g) cocoa powder

  • 1 tsp baking powder

  • 1/2 tsp baking soda

  • 1/4 tsp salt

  • 1/2 cup (120 ml) vegetable or canola oil

  • 1/2 cup (100 g) granulated sugar

  • 1/2 cup (100 g) brown sugar

  • 2 large eggs

  • 1 tsp vanilla extract

  • 1/4 cup (60 ml) milk

  • 3/4 cup (120 g) chocolate chips


Instructions

  • Preheat oven to 375°F (190°C). Line a 12-cup muffin tin with paper liners.

  • Grate zucchini and blot with paper towels—moist but not dripping.

  • In a bowl, whisk flour, cocoa powder, baking powder, baking soda, and salt.

  • In another bowl, mix oil, both sugars, eggs, vanilla, and milk until smooth.

  • Stir dry ingredients into wet until combined and glossy.

  • Fold in zucchini and chocolate chips.

  • Divide batter into muffin cups, filling ¾ full.

  • Bake for 20–25 minutes. Toothpick should come out with moist crumbs.

  • Cool in the pan 10–15 minutes, then transfer to a wire rack.

Notes

Keep zucchini slightly damp for best texture.

Use high-quality cocoa for richer flavor.

Sprinkle extra chocolate chips on top for more indulgence.

Muffins freeze well up to 2 months.

You can substitute half the oil with applesauce for a lighter option.
