Preheat oven to 350°F. Line a 12-cup muffin tin with parchment paper liners.
Using the fine side of a box grater, finely grate the zucchini (skin on) onto a clean dish towel or onto a stack of paper towels. Squeeze well to remove the excess water. Add to a large mixing bowl.
To the bowl with the zucchini, add wet ingredients: pumpkin, eggs, oil, and vanilla. Next add 1 cup of sugar and mix well.
In a medium mixing bowl, combine flour, cinnamon, baking powder, baking soda, and salt in medium bowl. Mix well.
Add flour mixture to pumpkin mixture and stir with a fork or whisk until just moistened and incorporated.
Optional: for extra fluff factor, allow batter to rest for 10-15 minutes.
Scoop batter into prepared muffin cups, adding approx. ¼ cup to each.
Bake in preheated oven for 23-25 minutes, checking for doneness with a toothpick inserted to the center of the muffin.
Allow muffins 10 minutes to cool in the pan then carefully remove. Allow to cool completely on a wire baking rack before diving in. (Flavors will be more pronounced once fully cooled.) Enjoy!
Notes
Feeling fancy? you can totally sprinkle some mini chocolate chips into the batter if desired. You can even go for a cupcake vibe and frost these muffins with cream cheese frosting.
