Method
Prepare the oven and zucchini
- Preheat the oven to 375°F and position a rack in the center; line a 12-cup muffin tin with liners or grease each cup.
- Shred zucchini on the large holes of a box grater or in a food processor; place shredded zucchini in a towel and squeeze until damp but not dripping.
Dry ingredients
- In a medium bowl whisk together flour, baking powder, baking soda, cinnamon, nutmeg, and salt.
Wet ingredients and batter
- In a large bowl whisk brown sugar, granulated sugar, and eggs until slightly frothy; whisk in oil, yogurt, and vanilla until smooth.
- Stir the squeezed zucchini into the wet mixture, then fold in the dry ingredients just until combined; fold in walnuts or chocolate chips if using.
Portion and bake
- Use a 1/3-cup scoop or 1/4-cup measuring cup to fill each muffin cup about three-quarters full; sprinkle coarse sugar on top if desired.
- Bake at 375°F for 18–22 minutes, rotating halfway if your oven is uneven; muffins are done when tops are golden and a toothpick shows moist crumbs but no raw batter.
Cool and store
- Cool muffins in the tin for 5 minutes, then transfer to a wire rack to cool 10–15 minutes before serving; store airtight at room temperature up to 2 days or refrigerate up to 5 days.
Notes
Squeeze zucchini until damp to avoid soggy centers; use a scoop for even muffins and consistent bake time. Swap half the flour for whole-wheat pastry flour for a nuttier flavor but expect slightly denser muffins. These freeze well individually wrapped for up to 3 months.
