Light, tender muffins loaded with chocolate! These Chocolate Zucchini Muffins are the best way to use up that garden zucchini this summer. The kids love these for breakfast or snack. Plus, with the addition of chocolate chips they are over the top delicious.

I’ve been all about the zucchini lately because we always end up with lots of it during the summer. It’s not unusual to find a bags of it on our front porch (thanks, neighbors!) and I can’t help buying some every time I see it at the farmer’s market.
I’ve shared zucchini banana bread and zucchini cookies and now I have another great recipe for you to try – chocolate zucchini muffins!
Why this Recipe Works!
- These muffins are so light and fluffy.
- Plus, they are loaded with chocolate chips and cocoa for the ultimate chocolate flavor.
- Can’t taste the zucchini, so no one knows you are sneaking vegetables in them.
- One bowl recipe, so they are quick and easy plus little clean up.
- Perfect for grab and go breakfasts or snacks.
- They freeze great s make a bunch to have on hand.
Unlike my chocolate zucchini cake, you can serve these any time of day. We love them – especially the kids! They always seem to disappear when I make a batch.
One Bowl Recipe!
If you can mix and stir you can make these muffins! This is a one-bowl muffin recipe and the batter comes together so quickly. Plus, these muffins always get rave reviews – I have yet to meet someone who doesn’t love them.
- In a large bowl, whisk together all-purpose flour, unsweetened cocoa powder, granulated sugar, brown sugar, baking powder, baking soda, and salt.
- Add the egg, melted butter, vanilla, and skim milk. Stir until the batter comes together.
- Fold in the shredded zucchini and chocolate chips. The batter will be thick!
- Divide the batter in a prepared muffin pan and bake them for 20 to 25 minutes or until a toothpick comes out clean. Cool them in the pan for 10 minutes and then transfer them to a wire rack
Tips for Baking with Zucchini
- Do I have to peel the zucchini? No, you don’t have to peel it! The peel is very tender and you can grate it right into the batter.
- Do I have to squeeze the liquid from the zucchini? No, I don’t like to wring the water out of the shredded zucchini. You want all of that moisture in the muffins.
- What size zucchini is best for this recipe? Choose a small to medium-sized one. I would avoid large ones because they tend to be drier and more stringy than the smaller ones. So, choose a four to six-ounce zucchini!
How to Freeze Muffins
One of the many things I love about this muffin recipe is that you can freeze them for later. Sometimes I make a double batch!
- Be sure to fully cool the muffins first.
- You can wrap them individually in freezer wrap or store them in a freezer bag or other freezer-safe container.
- They will keep in the freezer for up to three months!
- You can leave them at room temperature to thaw or warm them in the microwave.
I hope you love these easy zucchini muffins – it’s a recipe I love to make!

I made this recipe, and it’s wonderful! I had a little of the zucchini left over, so I said a prayer and grated it in the mix (about another 1/2 cup), and it’s good, light, and moist. Added some walnuts as well. Love that it’s not too sweet–my kids hate zucchini, but they love the chocolate muffins! Thank you for this recipe!
Sarah Hill says
What a great thing when the kiddos love it! I’m glad it turned out well for you! Thanks so much for commenting and rating!
Julie says
I added 1/4 cup milk and an egg due to batter being too
thick. Turned out well, not too sweet.

I’m glad you were able to make it work for you and enjoyed them!
