Method
Prepare and preheat
- Preheat the oven to 400°F and line a 12-cup muffin tin with liners or spray with nonstick spray.
Grate and drain vegetables
- Grate carrots and zucchini, then place shredded zucchini in a towel or paper towels and squeeze firmly to remove excess liquid until moist but not dripping.
Mix dry ingredients
- In a medium bowl whisk together flour, cinnamon, nutmeg, baking powder, baking soda, and salt.
Mix wet ingredients
- In a large bowl whisk brown sugar, granulated sugar, and egg until smooth; add oil, yogurt, and vanilla and whisk to combine.
Combine and fold
- Fold the drained shredded carrots and zucchini into the wet mixture, then gently fold in the dry ingredients until just combined; if using, fold in chopped walnuts.
Fill and bake
- Divide batter evenly among 12 cups, filling each about 3/4 full; bake at 400°F for 5 minutes, then reduce oven to 350°F and bake an additional 12–15 minutes until a toothpick shows moist crumbs but no raw batter.
Cool
- Let muffins cool in the tin for 8–10 minutes, then transfer to a cooling rack to finish cooling before serving or storing.
Notes
Squeeze shredded zucchini well to avoid excess moisture; if using frozen zucchini, thaw and drain thoroughly. Store cooled muffins in an airtight container at room temperature for up to 3 days, or freeze individually for up to 3 months. If muffins brown quickly, tent with foil and finish baking at 350°F.
