Ingredients

Scale
  • 2 cups (250g) all-purpose flour
  • 1/2 cup (50g) unsweetened cocoa powder
  • 1 teaspoon baking soda
  • 1 teaspoon baking powder
  • 1/4 teaspoon salt
  • 3/4 cup (150g) granulated sugar
  • 1/2 cup (120ml) vegetable oil
  • 2 large eggs, room temperature
  • 1 teaspoon vanilla extract
  • 1 1/2 cups (180g) grated zucchini, finely grated and squeezed dry
  • 1 teaspoon espresso powder (optional)
  • 1/4 cup (60ml) milk, whole or plant-based
  • 1/2 cup (90g) chocolate chips (optional)

Instructions

  1. Preheat your oven to 350°F (175°C). Grease your muffin pan or line with paper cups to prevent sticking.
  2. Grate the zucchini finely using a box grater or food processor. Place it in a clean kitchen towel and squeeze out as much moisture as possible.
  3. In a large bowl, whisk together the dry ingredients: all-purpose flour, unsweetened cocoa powder, baking soda, baking powder, and salt.
  4. In a separate bowl, beat the wet ingredients: granulated sugar, vegetable oil, eggs, vanilla extract, espresso powder (if using), and milk. Whisk until smooth and combined.
  5. Slowly fold the dry ingredients into the wet mixture using a spatula, mixing gently until just combined. Do not overmix.
  6. Fold in the grated zucchini and optional chocolate chips. The batter will be thick and slightly lumpy.
  7. Divide the batter evenly into the muffin cups, filling each about two-thirds full.
  8. Bake for 20-25 minutes. Check doneness by inserting a toothpick in the center; it should come out clean or with a few moist crumbs.
  9. Let muffins cool in the pan for 5 minutes, then transfer to a cooling rack to cool completely.

Notes

Squeeze out excess moisture from zucchini to avoid soggy muffins. Use room temperature eggs for better mixing. Avoid overmixing the batter to keep muffins tender. Adding espresso powder enhances chocolate flavor without coffee taste. Check muffins early at 18 minutes to prevent drying out. For extra moisture control, add a tablespoon or two of flour to grated zucchini if very watery.
