Ingredients and Substitutions

• 1/2 cup / 115 g / 4 oz salted butter, melted
• 1/2 cup / 100 g / 3.5 oz granulated sugar
• 2 large eggs, at room temperature
• 1 tbsp pure vanilla extract
• 1 3/4 cups / 210 g / 7.4 oz all-purpose flour, spooned and leveled
• 1 tsp baking powder
• 1 tsp baking soda
• 1 tsp ground cinnamon
• 1/4 tsp ground nutmeg
• 2 cups / 250 g / 8.8 oz shredded zucchini (2 medium or 1 large zucchini)
• 1 cup / 170 g / 6 oz semisweet chocolate chips

Step-by-Step Method

1. Preheat oven to 375°F (190°C) and line a 12-hole muffin pan with paper liners or grease the wells.
2. Shred zucchini with a box or handheld grater until you have 2 cups; do not drain.
3. Whisk together melted butter, granulated sugar, eggs, and vanilla until smooth.
4. Whisk together flour, baking powder, baking soda, cinnamon, and nutmeg until evenly combined.
5. Pour the wet mixture into the dry ingredients and gently fold with a rubber spatula just until combined (do not overmix).
6. Gently fold the shredded zucchini and semisweet chocolate chips into the batter until evenly distributed.
7. Scoop batter into prepared liners, filling each to the top; press extra chocolate chips on top if desired and optionally sprinkle turbinado sugar for crunchy tops.

8. Bake 18–23 minutes at 375°F until tops are golden and a toothpick inserted comes out clean or with a few moist crumbs.

9. Cool muffins in the pan for 10 minutes, then transfer to a wire rack to cool completely or serve warm.

Pro Tips for Best Results

• Measure your flour the right way: spoon it into your cup and level off, or better yet, weigh it. Too much flour means dense muffins, and we want light and tender.
• Use eggs at room temperature for smoother mixing and better texture. Take them out 20–30 minutes before baking.
• No draining the zucchini is key! The moisture keeps muffins soft and moist. But don’t let the batter sit too long once mixed or the zucchini will give off extra liquid and your muffins won’t rise as well.
• Stir gently and just until everything comes together — a few lumps won’t hurt and overmixing makes tough, chewy muffins.
• Fill your muffin cups to the top and don’t open the oven door for the first 12 minutes for nice high, domed muffins.
• Keep add-ins to about 1 cup combined — too much mix-ins weigh down the batter and can make uneven muffins.
• If you love a sweet crunch on your muffins, sprinkle turbinado or coarse sugar on top before baking.
• To freeze, pop muffins into the pan or on a baking sheet for about an hour so they firm up, then transfer to a freezer bag or container so they don’t get squished. Defrost overnight in the fridge or warm a bit in the microwave before eating.
• Butter adds richness and flavor, but you can swap in canola or vegetable oil for a lighter crumb. Light brown sugar also works beautifully and adds depth.

Flavor Variations and Swaps

• Spices: I love adding nutmeg here, but feel free to switch it up. Use just cinnamon or try warming spices like ginger, allspice, or cardamom for something different.
• Zucchini carrot muffins: For a veggie boost, mix 1 cup shredded zucchini with 1 cup shredded carrots.
• Lemon white chocolate: Add the zest of 2 lemons and swap semisweet chips for white chocolate chips for a bright, fresh twist.
• Nuts: Substitute chocolate chips with chopped walnuts or pecans. You can also mix nuts and chocolate chips, just keep total add-ins around 1 cup.
• Dried fruit: Replace half the chocolate chips with 1/2 cup of golden raisins or dried cranberries for a chewy burst of sweetness.

How to Store and Freeze

• Countertop: These zucchini chocolate chip muffins stay fresh at room temperature for 2 to 3 days in an airtight container.
• Refrigerator: Store them in a sealed container for up to one week.
• Freezing: Let muffins cool completely before putting them in a freezer bag. To keep their shape, freeze them in the pan or on a baking sheet for about an hour first, then transfer to a bag or container. They last up to 3 months this way! Thaw overnight in the fridge before reheating.
• Reheating: Want that fresh-baked feel? Microwave for 20-30 seconds or warm in a 325°F oven for a few minutes until cozy warm.

Notes

Use paper liners: They’re a huge help for easy muffin release and cleanup. If you bake without them, grease your pan wells well.

No need to drain the zucchini: The liquid helps keep muffins moist and tender. Just grate and mix in.

Peeling zucchini: Not necessary. But if your kids are picky, peel it off. Yellow summer squash is a good swap too.

Don’t let batter sit: Sugar pulls moisture from zucchini fast, and baking soda reacts quickly. Get the muffins in the oven right after mixing.

Crunchy tops: Sprinkle turbinado or coarse sugar on top before baking for a sweet, crunchy finish.

Common Questions Answered

Q: Will the muffins taste like zucchini? A: No way! The shredded zucchini mostly disappears into the batter but adds lovely moisture and tenderness, especially with cinnamon and chocolate chips masking its flavor.

Q: Should I drain the shredded zucchini? A: Nope! We rely on its moisture for soft muffins. Just grate and add directly into the batter.

Q: Can I use frozen zucchini? A: You can, but thaw and squeeze out most of the water first. Otherwise the batter gets too wet and baking times might shift.

Q: How can I make these dairy-free or egg-free? A: For dairy-free, swap melted butter with neutral oil like canola. For egg-free, substitute each egg with a flax egg (1 tbsp ground flaxseed + 3 tbsp water), though the texture may be a bit different and baking time slightly longer.

Q: Can I make mini muffins or double the recipe? A: Absolutely! Mini muffins bake faster, so start checking around 10-12 minutes. To double, just use two pans and bake together, rotating halfway if needed to bake evenly.

Q: How should I store leftovers? A: Keep muffins in an airtight container at room temperature for 2-3 days, refrigerate up to a week, or freeze up to 3 months. Reheat gently before eating.

Q: Can I make these gluten-free? A: Yes! Use a 1:1 gluten-free flour blend with xanthan gum. The texture may be a little different, but it works well.

Q: Can I reduce the sugar? A: You can try decreasing the sugar a little, but cutting too much affects tenderness and browning.
