What You’ll Need

• 1 1/3 cups grated zucchini
• 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), I prefer to use whole milk or 2%, but any will work
• 3/4 cup chocolate chips (135 grams)

How to Make the Muffins

1. Preheat the oven to 375°F (190°C) and line a 12-cup muffin pan with paper liners.
2. Trim the zucchini ends and grate the zucchini using a fine grater.
3. Lightly blot the grated zucchini with paper towels to remove excess moisture (do not squeeze dry).
4. In a large bowl, whisk together the flour, cinnamon, nutmeg, baking powder, baking soda, and salt.
5. In a separate bowl, whisk together the oil, brown sugar, granulated sugar, eggs, vanilla, and milk until smooth and lump-free.
6. Make a well in the center of the dry ingredients and pour in the wet ingredients.
7. Gently fold the batter by hand until about 80% combined, leaving a few streaks of flour.
8. Stir in the grated zucchini.
9. Fold in the chocolate chips.

10. Spoon the batter into the prepared liners, filling each about 3/4 full (about 12–14 muffins).
11. Bake one tray at a time on the middle oven rack for 22–25 minutes, or until a toothpick inserted in the center comes out clean or with a few dry crumbs.
12. Cool the muffins in the pan for about 10 minutes, then transfer to a wire rack to cool completely or serve warm.

Expert Tips for Best Results

• Use a fine grater for the zucchini so the shreds collapse into the batter and the muffins remain tender.
• Blot the zucchini lightly with paper towels to remove excess moisture; do not squeeze it dry or the texture will change.
• Measure flour by spooning into the cup and leveling with a knife to avoid dry, dense muffins.
• Fold the batter by hand and stop when it’s about 80% combined — overmixing causes tougher muffins.
• Line the pan with paper liners to prevent chocolate chips from sticking to the tin.
• If your zucchini is very watery, add 1–2 tablespoons more flour to the dry mix to prevent overly loose batter.
• Bake one tray at a time in the middle of the oven for most even results; if using two racks, rotate pans halfway through and watch closely.

Flavor Variations and Substitutions

• Chocolate swap: use milk, semi-sweet, dark, or white chocolate chips, or a mix for varied sweetness.
• Nuts: fold in 1/2 cup chopped walnuts or pecans for crunch.
• Spice changes: add 1/2 teaspoon ground ginger or increase cinnamon for a warmer spice profile.
• Healthier swap: replace half the oil with unsweetened applesauce for a slightly lighter muffin (texture will be a bit different).
• Flour options: use a 1:1 gluten-free baking blend in place of all-purpose flour, or replace up to half the flour with whole wheat pastry flour.
• Mini muffins: make mini muffins (about 24) and reduce bake time to 12–15 minutes.
• Streusel topping: mix 1/4 cup brown sugar, 2 tablespoons flour, and 2 tablespoons cold butter and sprinkle on top before baking for a crunchy topping.

Storing, Freezing, and Reheating

• Room temperature: Store cooled muffins in an airtight container at room temperature for up to 3 days.
• Refrigerator: Refrigerate for up to 1 week if you prefer a firmer texture; bring to room temperature or warm briefly before serving.
• Freezing: Freeze baked muffins in a single layer on a tray until firm, then transfer to a freezer-safe bag or container for up to 2 months. Thaw in the refrigerator or at room temperature.
• Reheating: Warm a muffin in the microwave for 10–20 seconds, or in a 325°F (160°C) oven for 5–8 minutes until warmed through. From frozen, reheat at 325°F for 12–18 minutes until hot.
• Make-ahead: Bake and freeze immediately if preparing ahead. This recipe’s batter is not ideal for freezing raw; freeze finished muffins instead.

Answers to Common Questions

• Can I leave out the chocolate chips? Yes. The muffins will still be moist and flavorful; you can fold in dried fruit, nuts, or leave them plain.
• Do I need to squeeze the zucchini dry? No — just blot lightly with a paper towel to remove excess surface moisture. Squeezing too much removes moisture that keeps the muffins tender.
• Why are my muffins dense? Overmixing the batter, packing the flour into the measuring cup, or using overly wet zucchini can cause density. Mix until just combined and measure flour correctly.
• Can I make these into a loaf instead of muffins? Yes — transfer batter to a greased 9×5-inch loaf pan and bake at 350°F (175°C) for about 50–60 minutes, or until a toothpick comes out clean.
• Can I use a different oil? Yes. Neutral oils like canola, sunflower, or light olive oil work well. You can also substitute half the oil with applesauce to reduce fat.
• How do I know when they’re done? A toothpick inserted into the center should come out clean or with a few dry crumbs. If there is wet batter on the toothpick, bake a few minutes longer.
