Chocolate and zucchini might sound like an unlikely match, but once you’ve tried these healthy chocolate zucchini muffins, you’ll be hooked. They’re rich and chocolaty with a soft, moist texture — thanks to grated zucchini, which blends right in without leaving any veggie taste behind.
Whether you’re trying to use up an overflowing summer garden or just looking for a better-for-you chocolate treat, these muffins are the answer.
Made with wholesome ingredients, less sugar, and zero butter, they’re the kind of snack you can feel good about — kid-friendly, freezer-friendly, and great for breakfast, snacks, or dessert.
Ingredients
- 1 cup whole wheat flour
- 1/2 cup all-purpose flour
- 1/2 cup unsweetened cocoa powder
- 1 teaspoon baking soda
- 1/2 teaspoon baking powder
- 1/2 teaspoon salt
- 1 teaspoon ground cinnamon (optional)
- 2 large eggs
- 1/3 cup honey or maple syrup
- 1/3 cup plain Greek yogurt
- 1/4 cup olive oil or melted coconut oil
- 1 teaspoon vanilla extract
- 1 1/2 cups finely grated zucchini (about 1 medium zucchini, squeezed dry)
- 1/3 cup unsweetened applesauce
- 1/2 cup mini chocolate chips (plus more for topping, optional)
Start with the Dry Ingredients
In a large bowl, whisk together the whole wheat flour, all-purpose flour, cocoa powder, baking soda, baking powder, salt, and cinnamon if using. Cocoa powder gives the muffins their rich chocolate base, while the whole wheat flour adds extra fiber and a subtle nutty flavor.
Mix the Wet Ingredients
In another bowl, whisk together the eggs, honey or maple syrup, yogurt, oil, and vanilla. Stir in the grated zucchini and applesauce. Make sure the zucchini is well-drained — you can press it between paper towels to remove excess moisture. This step is key to keeping the batter from getting too wet.
The combination of applesauce and Greek yogurt helps keep the muffins tender without needing a lot of oil.
Combine the Batter
Pour the wet ingredients into the dry ingredients and mix until just combined. Don’t overmix or the muffins could end up dense. Gently fold in the chocolate chips, saving a few to sprinkle on top.
The batter will be thick and dark, and you might not even notice the zucchini — it practically disappears into the chocolatey mixture.
Bake to Perfection
Preheat your oven to 350°F (175°C). Line a 12-cup muffin pan with paper liners or grease it lightly with oil.
Divide the batter evenly among the cups, filling each about 3/4 full. Sprinkle extra chocolate chips on top if you like a prettier finish.
Bake for 18–22 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs. Let the muffins cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.
Why These Muffins Work
These muffins are a win-win: indulgent enough to satisfy your sweet tooth, but packed with wholesome ingredients that add nutrients and cut down on processed sugar.
- Zucchini keeps them moist without extra fat.

- Whole wheat flour adds fiber and makes them more filling.
- Cocoa powder and mini chocolate chips give rich flavor without needing a lot of added sugar.

Make-Ahead and Storage Tips
These muffins keep well in an airtight container at room temperature for 2–3 days or in the fridge for up to 5 days. They also freeze beautifully.
To freeze: Let the muffins cool completely, then place them in a single layer in a freezer-safe bag or container. They’ll keep for up to 2 months. Reheat in the microwave for 20–30 seconds or let thaw overnight.
They’re great for meal prep — grab one on your way out the door or pack in a lunchbox.
Customizations and Add-Ins
Want to switch things up? Try these easy tweaks:
- Add chopped walnuts or pecans for crunch.
- Stir in a spoonful of peanut butter or almond butter for richness.

- Make them vegan by using flax eggs, dairy-free yogurt, and maple syrup.
