Chocolate Zucchini Muffins That Don't Get Soggy (Finally)

Equipment

  • Box Grater
  • 12-cup standard muffin tin
  • Large Mixing Bowl
  • Whisk
  • Ice cream scoop or 1/3-cup measuring cup
  • Wire cooling rack

Ingredients
  

  • 1 1/2 cups all-purpose flour
  • 1/2 cup unsweetened cocoa powder
  • 1 teaspoon baking soda
  • 1/2 teaspoon baking powder
  • 1 teaspoon ground cinnamon
  • 1/2 teaspoon salt
  • 1 cup shredded zucchini (from 1 medium zucchini)
  • 1/2 cup neutral oil (coconut or avocado work well)
  • 3/4 cup brown sugar (packed)
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1 cup chocolate chips

Instructions
 

  • Preheat the oven to 350°F (175°C). Line a 12-cup muffin tin with foil liners or grease it well.
  • Wash and trim the ends of the zucchini. Grate it on the large holes of a box grater. Do not squeeze out the moisture. Set aside.
  • In a large bowl, whisk together the flour, cocoa powder, baking soda, baking powder, cinnamon, and salt. Measure out 1 tablespoon of this mixture and toss it with the shredded zucchini. Set both aside.
  • In another bowl, whisk together the oil and brown sugar until smooth. Add the eggs one at a time, then the vanilla. Whisk until glossy and smooth like thin caramel.
  • Pour the wet ingredients into the dry. Stir with a spatula until just combined – a few streaks of flour are fine. Do not overmix.
  • Gently fold in the flour-coated zucchini and most of the chocolate chips (reserve a handful for topping). The batter will be thick.
  • Divide the batter evenly among the 12 muffin cups, filling nearly to the top. Press reserved chocolate chips onto the tops.
  • Bake for 18–22 minutes, until the tops spring back when gently pressed and a toothpick inserted into the center comes out with a few moist crumbs.
  • Let the muffins cool in the tin for 5 minutes, then transfer to a wire rack to cool completely. Do not skip the wire rack – it prevents soggy bottoms.

Notes

Use foil-lined paper liners to prevent sticking. For the best texture, let the zucchini sit in a bowl while you measure other ingredients – do not squeeze it dry. Store in an airtight container at room temperature for up to 3 days, or freeze individually wrapped for up to 3 months. Reheat from frozen: microwave 30 seconds or warm in a 300°F oven for 8 minutes.
