Method
Prepare and preheat
- Preheat oven to 375°F and line a 12-cup muffin tin with paper liners or grease lightly.
Shred and drain
- Coarsely shred the zucchini and carrot on a box grater or with a food processor; measure about 1 1/2 cups combined and place in a towel to squeeze out free liquid until the shreds are tacky not dripping.
Mix dry ingredients
- In a medium bowl whisk together the flour, baking powder, baking soda, cinnamon, nutmeg, and salt.
Mix wet ingredients
- In a separate bowl whisk the eggs, brown sugar, oil, Greek yogurt, and vanilla until smooth, then pour the wet into the dry and stir briefly until most streaks of flour disappear.
Combine and add mix-ins
- Fold the squeezed shredded zucchini and carrot into the batter along with the walnuts or raisins if using, mixing just until combined.
Portion and bake
- Divide batter among the 12 muffin cups, filling each about 3/4 full, and bake at 375°F for 18 to 22 minutes until a toothpick comes out with a few moist crumbs and tops spring back.
Cool and finish
- Let muffins cool in the pan for 8 to 10 minutes, then transfer to a wire rack to cool completely; if using coarse sugar or a light frosting, apply when muffins are fully cool.
Notes
Squeeze excess liquid from zucchini to prevent soggy muffins; if batter is loose add 1–2 tablespoons extra flour. Store at room temperature up to 2 days or refrigerate up to 4 days. To freeze, wrap cooled muffins individually and freeze up to 3 months; reheat at 325°F for 12–15 minutes from frozen.
