What You’ll Need

• 1 1/3 cups grated zucchini (lightly blot to remove some surface moisture; do not squeeze dry)
• 2 cups all-purpose flour (250 grams)
• 1 teaspoon cinnamon
• 1/4 teaspoon ground nutmeg
• 1 teaspoon baking powder
• 1/2 teaspoon baking soda
• 1/4 teaspoon salt
• 1/2 cup vegetable oil (120 ml), or canola
• 1/2 cup brown sugar (105 grams), light or dark
• 1/3 cup granulated sugar (67 grams) (use 1/2 cup if you prefer sweeter muffins)
• 2 large eggs
• 2 teaspoons vanilla extract
• 1/4 cup milk (60 ml) (whole milk or 2% preferred, any will work)
• 3/4 cup chocolate chips (135 grams)

Make the Muffins

1. Preheat oven to 375°F (190°C) and line a 12-cup muffin pan with paper liners.
2. Trim the zucchini ends and grate finely to yield about 1 1/3 cups.
3. Lightly blot the grated zucchini with a paper towel to remove excess surface moisture without squeezing it dry.
4. In a large bowl whisk together 2 cups all-purpose flour, 1 teaspoon cinnamon, 1/4 teaspoon nutmeg, 1 teaspoon baking powder, 1/2 teaspoon baking soda, and 1/4 teaspoon salt.
5. In a separate bowl whisk 1/2 cup vegetable oil, 1/2 cup brown sugar, 1/3 cup granulated sugar, 2 large eggs, 2 teaspoons vanilla extract, and 1/4 cup milk until smooth.
6. Make a well in the dry ingredients and pour the wet mixture into the center.
7. Gently fold the ingredients together by hand with a spatula until the batter is about 80% combined (a few lumps or streaks are okay).
8. Fold the grated zucchini into the batter.

9. Fold in 3/4 cup chocolate chips.

10. Scoop the batter into the lined muffin cups, filling each about three-quarters full (about 12–14 muffins).
11. Bake one pan at a time on the oven’s middle rack for 22–25 minutes, or until a toothpick inserted in the center comes out clean or with a few crumbs.
12. Cool the muffins in the pan for about 10 minutes, then transfer them to a wire rack to cool completely.

Baking Tips for Best Results

• Use a fine grater for zucchini so it blends well and keeps muffins tender and soft.
• Blot the zucchini gently to remove just enough moisture — too much liquid can make muffins soggy, too little can dry them out.
• Mix the batter just until combined to avoid tough, dense muffins from overworking the flour.
• If you notice chocolate chips sinking to the bottom, try mini chips or toss your chips in a tablespoon of flour before folding them in to help them suspend better.
• Spoon the flour into your measuring cup, then level it off instead of scooping directly to avoid grabbing too much flour, which can make muffins heavy.
• Bake muffins in the center of your oven to ensure even heat distribution. If your oven runs hot or uneven, check muffins early and rotate the pan if needed.
• For a pretty top, press a few extra chocolate chips on each muffin before popping them in the oven.

Mix-Ins and Substitutions

• Swap chocolate chips: try milk, semi-sweet, white, or dark varieties—or mix them up!
• Add nuts: fold in 1/2 cup chopped walnuts or pecans for a nice crunch.
• Change the spice: add 1/2 teaspoon ground ginger or a pinch of cloves to change the cozy flavor profile.
• Whole grain option: replace up to 1/2 cup of all-purpose flour with whole wheat flour for a heartier texture.
• Add fruit: toss in 1/2 cup raisins, dried cranberries, or small chopped apple pieces to mix up flavors.
• Topping idea: a simple streusel made of butter, flour, and brown sugar sprinkled on top before baking adds a crisp finish.
• Make a loaf: double the batch and bake in a 9×5-inch loaf pan at 350°F (175°C) for 50 to 65 minutes, testing doneness with a toothpick.

Storage and Freezing Tips

Keep your baked zucchini chocolate chip muffins fresh by storing them in an airtight container at room temperature for up to 3 days. If you refrigerate, tuck them in an airtight container for up to 4 days—the chill will firm them up slightly.

• Freezing: Let muffins cool completely before wrapping each one individually in plastic wrap or placing them in a freezer bag. They freeze well for up to 2 months. Thaw them in the fridge or at room temperature. For a quick warm-up, microwave a thawed muffin for 15–25 seconds or pop it in a 325°F (160°C) oven for 8–10 minutes.
• Make-ahead: You can grate zucchini a day ahead and keep it refrigerated—just blot it before using. I don’t recommend mixing the batter ahead of time because leavening agents start working and muffins may not rise as well. Instead, bake fresh or freeze baked muffins for later.

Common Questions

• Can I use frozen zucchini? Absolutely! Just thaw it first and blot away any excess moisture to keep your batter from becoming watery.
• Can I reduce the sugar? You sure can. The recipe suggests up to 1/2 cup granulated sugar for a sweeter version, but you can lower either sugar a bit to suit your taste. Just remember, cutting too much sugar might change the texture and browning.
• Can I substitute the oil? Yes! Melted butter works great 1:1 and gives a richer flavor. Neutral oils like canola also work. Using applesauce instead of oil reduces fat but can make muffins less tender.
• How do I know when they’re done? A toothpick poked in the center should come out clean or with a few dry crumbs. The muffin tops should be golden and firm to the touch.
• Can I make mini muffins? Definitely. Use a mini muffin tin and reduce baking time to about 12–16 minutes, checking early for doneness.
• Can this be made gluten-free? You can try swapping flour for a 1:1 gluten-free baking blend, making sure it has a binder like xanthan gum. Expect a slight texture difference, but it should work nicely.
