What You’ll Need
- Grated zucchini: You’ll need about 1 large or 1 ½ medium zucchini grated (no need to peel!). Don’t worry, you won’t even taste the vegetables in these chocolate muffins!
- All-purpose flour: You can substitute with whole wheat flour, but the end result will be slightly more dense and chewier.
- Dutch process cocoa powder, or other unsweetened cocoa powder: This adds an intense chocolate flavor that is so, so delicious.
- Baking soda and baking powder: To make sure the chocolate muffins rise up!
- Kosher salt: To season the muffins.
- Canola oil: To keep the muffins tender and moist. We prefer this it butter when baking these muffins.
- Whole milk Greek yogurt: We LOVE baking with Greek yogurt! The texture can’t be beat. Check out these mini blueberry muffins and this blueberry coffee cake, both baked with Greek yogurt. My personal favorite brand is FAGE.
- Brown sugar: For added sweetness
- Granulated sugar: For added sweetness
- Eggs: You’ll want the eggs to be room temperature for baking.
- Pure vanilla extract: This helps to bring out the chocolate flavor in the muffins
- Mini semi-sweet chocolate chips: Mini chocolate chips are our preference for muffins, as they retain their shape and get a little chocolate in every bite. We love them in our Easy Banana Chocolate Chip Muffins!
- Flaky sea salt, optional, but highly recommended!
- Nonstick cooking spray: We recommend Baker’s Joy, it’s the best!!
Equipment: 2 large mixing bowls, a whisk, rubber spatula (my favorite brand is GIR), a standard muffin tin, muffin liners, a cookie scoop





How To Make Chocolate Zucchini Muffins
- Preheat an oven to 375F, then prepare a muffin tin with muffin or cupcake liners.
- Whisk the dry ingredients in a mixing bowl, then whisk the wet ingredients together in a separate large bowl.
- Fold the grated zucchini into the wet ingredients.
- Dump the dry ingredients into the wet, then fold to gently combine the batter. With only a few streaks of flour remaining, stir in the mini chocolate chips.
- Use a cookie scoop to evenly divide the batter into the prepared muffin pan, then bake for 18-20 minutes, or until a toothpick or cake tester comes out clean.
- Allow the chocolate zucchini muffins to cool for about 5 minutes, then transfer to a wire rack to cool completely. Sprinkle each with a pinch of flaky sea salt.


Do You Need To Peel The Zucchini?
No, don’t waste your time! Trim off the ends of the zucchini, then grate with a box grater on the side with the smallest holes.
Can These Zucchini Muffins Be Made Gluten-Free?
We haven’t tested these muffins with gluten-free flour, but for all GF baking, we recommend Bob’s Red Mill 1-for-1 gluten-free flour. If you try it, let us know what you think!

Should You Drain The Zucchini?
Nope! Squeezing out the excess moisture isn’t necessary.
Are These Muffins Freezer-Friendly?
Yes! Allow chocolate zucchini muffins to cool completely to room temperature, then store in a single layer in an airtight container (such as a large Ziploc bag). If stacking them in a freezer safe tupperware, place a sheet of parchment paper in between. Freeze for up to 3 months.
- To reheat from frozen: Either thaw overnight or heat in a microwave on high until warm throughout. We recommend placing a damp paper towel on top of the muffin and reheating in 30 second increments to make sure you don’t overdo it.
- To reheat fresh muffins: The absolute BEST way to do this is to slice them in half from top to bottom, then warm cut side down in a skillet with a little butter over medium heat. You’ll end up with a warm, griddled muffin with crisp edges and a tender center.

This is such an easy, fun recipe to celebrate one of the most abundant summer veggies, and kids can make it! Plus, the combination of chocolate and flaky sea salt is just heaven.
