What Kind of Zucchini Works Best?

Any standard green zucchini will do the trick. Choose firm, small-to-medium-sized ones for best flavor and moisture. Avoid overly large zucchini with tough skins or big seeds. There’s no need to peel them—the green flecks disappear during baking.

Ingredients for the Double Chocolate Zucchini Muffins

Zucchini: The secret weapon for moisture and nutrition without overpowering flavor.

All-purpose flour: Provides structure and balances the moist zucchini.

Unsweetened cocoa powder: The base of our chocolate flavor. Choose Dutch-process for a richer hue.

Granulated sugar & brown sugar: A combo for sweetness and extra softness.

Baking soda & baking powder: These give rise and lift to the batter.

Salt: Balances sweetness and enhances flavor.

Eggs: For binding and richness.

Vegetable oil: Keeps things moist and helps bind everything together.

Vanilla extract: Enhances the chocolate flavor profile.

Chocolate chips: Stirred into the batter and sprinkled on top for double chocolate bursts.

How To Make the Double Chocolate Zucchini Muffins

Step 1: Prep and Preheat

Preheat your oven to 350°F (175°C) and line a 12-cup muffin pan with paper liners. Lightly grease them if desired.

Step 2: Shred and Drain Zucchini

Grate 1 cup of zucchini (about 1 medium). Place in a clean towel and squeeze out excess moisture. Don’t skip this step—it prevents soggy muffins.

Step 3: Mix Wet Ingredients

In a large bowl, whisk together 2 eggs, 1/2 cup vegetable oil, 1/2 cup granulated sugar, 1/4 cup brown sugar, and 1 tsp vanilla extract until smooth and combined.

Step 4: Add Zucchini

Fold in the drained shredded zucchini until evenly distributed.

Step 5: Combine Dry Ingredients

In a separate bowl, whisk together 1 cup all-purpose flour, 1/2 cup unsweetened cocoa powder, 1/2 tsp baking soda, 1/2 tsp baking powder, and 1/4 tsp salt.

Step 6: Combine Wet and Dry Mixtures

Add the dry ingredients to the wet and mix just until combined—don’t overmix. Fold in 3/4 cup chocolate chips.

Step 7: Fill Muffin Cups

Divide the batter evenly among the 12 muffin liners. Top each with a few extra chocolate chips for visual appeal.

Step 8: Bake

Bake for 18–22 minutes or until a toothpick inserted into the center comes out with just a few moist crumbs.

Step 9: Cool and Serve

Let muffins cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.

Serving These Muffins

These muffins are perfect for breakfast, snacks, or dessert. They yield 12 muffins, making them ideal for small families or meal prepping. Serve them warm with a smear of nut butter or a glass of milk, or enjoy straight from the fridge.

How To Store Double Chocolate Zucchini Muffins

Room Temperature: Store in an airtight container for up to 3 days.

Frequently Asked Questions

Can I use whole wheat flour instead?
Yes! Sub half or all of the all-purpose flour with whole wheat flour. Expect a denser muffin but still delicious.

Should I peel the zucchini?
Nope! The skin softens as it bakes, and the flecks are barely visible in the final muffin.

Can I add nuts or other mix-ins?
Absolutely. Walnuts or pecans add great crunch. Just keep total add-ins to 1 cup max.

Can I make these dairy-free?
Yes—use dairy-free chocolate chips and ensure your cocoa powder is dairy-free.

Why did my muffins come out too wet?
You likely didn’t squeeze enough moisture from the zucchini. Be sure to wring it out well.
