Method
Prep the oven and tin
- Preheat the oven to 350°F and line a 12-cup muffin tin with paper liners.
- Set the tin aside while you mix the batter.
Mix dry and wet batter
- Whisk the all-purpose flour, unsweetened cocoa powder, baking soda, baking powder, and salt in a large bowl until evenly combined.
- In a separate bowl, beat the eggs, granulated sugar, brown sugar, vegetable oil, plain yogurt, and vanilla extract until smooth.
- Stir the wet mixture into the dry mixture until just combined, stopping as soon as no dry streaks remain.
Add zucchini, carrots, and chocolate chips
- Fold in the zucchini and carrots, then fold in 1/2 cup of the semi-sweet chocolate chips.
- Divide the batter evenly among the muffin cups, filling each 3/4 full.
- Top each muffin with the remaining semi-sweet chocolate chips.
Bake and cool
- Bake at 350°F for 20–22 minutes, until a toothpick comes out with a few moist crumbs.
- Cool in the pan for 5 minutes, then transfer muffins to a wire rack to finish cooling.
Notes
Pro tip: squeeze the grated zucchini well so the muffins bake with a fudgy crumb instead of turning gummy. Store airtight at room temperature for up to 3 days or refrigerate up to 5 days; freeze up to 2 months. Dietary swap: use dairy-free yogurt in a 1:1 substitution for similar moisture.
