Chocolate for breakfast? With these Chocolate Zucchini Muffins, the answer is a confident yes. Rich, moist, deeply chocolatey, and secretly packed with vegetables, these muffins are proof that indulgence and nutrition can live happily in the same bite. Best of all, they’re made in one bowl, which means minimal cleanup and maximum baking joy.

Zucchini might sound like an unusual addition to chocolate muffins, but it’s the quiet hero of this recipe. Once baked, it completely disappears into the batter, leaving behind nothing but incredible moisture and a tender crumb. Even picky eaters won’t suspect there’s a vegetable involved—making these muffins perfect for kids, skeptics, and chocolate lovers alike.

Whether you’re looking for a healthier snack, a lunchbox-friendly treat, or a cozy baking project that doesn’t require fancy equipment, these chocolate zucchini muffins deliver every time.

Why Chocolate and Zucchini Work So Well Together

Zucchini has a naturally mild flavor and high water content. When grated and folded into baked goods, it releases moisture as it bakes, resulting in soft, fluffy textures without the need for excess oil or butter. Cocoa powder and chocolate chips easily overpower zucchini’s subtle taste, making it essentially invisible.

This combination has been popular in home baking for decades, especially in late summer when zucchini is abundant. It’s a smart, economical way to use up garden produce while creating something truly crave-worthy.

Ingredients

All-purpose flour
Unsweetened cocoa powder
Baking soda
Baking powder
Salt
Cinnamon (optional but recommended)
Eggs
Brown sugar
Granulated sugar
Neutral oil (vegetable or avocado oil)
Vanilla extract
Milk (or plant-based milk)
Finely grated zucchini (unpeeled)
Chocolate chips or chunks

Instructions

Preheat your oven to 350°F (175°C). Line a muffin tin with paper liners or lightly grease it.
In a large mixing bowl, whisk together the eggs, brown sugar, and granulated sugar until smooth and glossy.
Add oil, milk, and vanilla extract. Whisk until fully combined.
Sift in the flour, cocoa powder, baking soda, baking powder, salt, and cinnamon. Gently fold until just combined—do not overmix.
Fold in the grated zucchini. Do not squeeze out the moisture; it’s essential for soft muffins.
Stir in chocolate chips, reserving a few for topping.
Divide batter evenly among muffin cups, filling about ¾ full. Sprinkle remaining chocolate chips on top.
Bake for 18–22 minutes, or until a toothpick inserted comes out with a few moist crumbs.
Cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.

Pro Tips for Perfect Chocolate Zucchini Muffins

Grate zucchini finely
Large shreds can create uneven texture. A fine grate ensures it melts seamlessly into the batter.

Don’t squeeze the zucchini
Its moisture is crucial. Removing it will result in dry muffins.

Avoid overmixing
Overmixing activates gluten and leads to dense muffins. Stop as soon as the flour disappears.

Use quality cocoa powder
A good cocoa powder dramatically improves flavor depth.

Variations & Substitutions

Whole wheat version: Replace half the flour with whole wheat flour
Dairy-free: Use almond or oat milk
Refined sugar-free: Substitute coconut sugar
Vegan: Use flax eggs and dairy-free chocolate chips
