Loaded with shredded zucchini and chocolate chips, these zucchini muffins make a wholesome on-the-go breakfast or after school snack.

zucchini chocolate chip muffins

When it comes to before-school breakfasts for the kids, I know how easy it is to fall back on sugary cereals and processed foods (guilty!), so I’m always trying to come up with new ideas that are a little more wholesome. These zucchini muffins are a new fave. With two bowls and a muffin tin, you can whip them up in just 35 minutes. What’s more, kids love them and they’re a great way to sneak in a little extra protein and vegetables. Feel free to replace half of the all-purpose flour with whole-wheat flour, or swap out the chocolate chips and nuts for your favorite add-ins.

What you’ll need To Make Zucchini Muffins

To Make Zucchini Muffins

Begin by shredding the zucchini. I use a food processor — makes it easy — but it’s fine to grate by hand. There is no need to wring out the shredded zucchini.

  • Tasty muffins. I cut back the sugar very slightly but otherwise followed the recipe. I had a large zucchini so I cut off about a 4 inch chunk and shredded it for about 2 cups (didn’t measure). Added chopped walnuts. Didn’t have nutmeg. Will cut the cinnamon down to 1tsp next time. Tip: don’t put the choc chips on top, makes it hard to eat without getting melted chocolate everywhere.

  • We are loving these generous size muffins! I subbed half whole wheat flour and reduced sugar to 1/2 cup + 1/4 cup maple syrup. Flavor is excellent. We love nuts, but we thought the walnuts kind of took over the muffin. Might cut back next time. Thanks for a delicious recipe!

  • I needed to use a zucchini and had a half bag of dark chocolate chunks in the refrigerator, so this recip was perfect. Instead of additional chips on top, I dusted them with a few grinds of Trader Joe’s Chocolate, Sugar and Coffee grinder mix. I haven’t seen it in stores recently, so it might be discontinued, but it’s really a fun topping for baked goods. The muffins came out extremely moist and tasty. Thanks for the recipe!

  • I love this recipe!! I added flax seed meal and 2 tablespoons of cocoa powder and they were even more delicious!! I also shredded the zucchini super finely (roughly half the width of a spaghetti noodle) so that my kids would not notice it as much.

    • Hi Karen, You could reduce the sugar by 1/4 cup; I wouldn’t cut out much more or it will change the texture of the muffins. The baking temperature can remain the same; I’d start checking them for doneness at 10 – 15 minutes. Hope your grandkids enjoy! 🙂

  • Fantastic!!! I love how fresh tasting these are; I shredded the zucchini and while it is cooked it was still very much “present” in flavor and moisture. I used half whole wheat flour and half all purpose flour.

  • Hi, I’m wondering if it’s possible to use white whole-wheat flour instead of all-purpose flour. If so, are there any adjustments I need to make? Thanks!

    • — Tracy on January 20, 2019
    • Reply
    • White whole wheat should work here with no adjustments, but because whole wheat flour can change the texture of baked goods, I’d suggest starting out replacing half of the all-purpose flour with whole wheat. If you like the texture of the muffins, you can up the ratio of whole wheat to all purpose flour the next time you bake them. Hope that helps!

  • We made these and didnt love them so tweaked it the next time.
    We used just over half a cup of brown sugar and doubled the courgette and added 2T of boiling water. They were amazing!!! Super soft and not over sweet.
    We also used half milk chocolate and half dark chocolate chips

  • Just the recipe that I had in mind when I searched online – perfect! I substituted whole wheat pastry flour for half of the flour, and used a little less brown sugar than suggested in the recipe. I think that I will go down to 3/4 cup next time since we are not fans of a lot of sugar. I used walnuts and bittersweet chips and the muffins are soooooo good and they have a great texture. Thanks for sharing this recipe!

  • These were delicious and moist. My daughter helped me with them and enjoyed the process and result! I added a couple scoops of chocolate protein powder and cut back that same amount on the flour. That way I can give them to the kids for breakfast on- the -go. Thank you Jenn, your recipes are all wonderful!

  • Delicious warm with a tall, cold glass of milk. Tastes like a healthy chocolate chip cookie! I made the mistake of just adding the extra 2 T of chocolate chips to the batter, rather than reserving them for on top of the muffins. I think they would look more appealing if I would have followed the recipe as written. Thanks Jen for another 5 star recipe!

  • Hi Jenn, Just like everyone else, I love your recipes. Do you think this recipe would work with a natural sweetner like honey, apple sauce or a combo of both?
    Thanks in advance!

    • — Nora on August 2, 2018
    • Reply
    • Hi Nora, I’m always a bit hesitant to suggest using honey as a substitute for sugar in baking as it doesn’t always guarantee good results. Honey also can cause things to burn more quickly. If you’d like to use some applesauce, that can be a substitute for butter. You can get away with replacing half the butter here with applesauce. Hope that helps and would love to hear how the muffins turn out if you try them with any tweaks!

    • Palm (coconut) sugar swaps out nicely in baking. I always sub applesauce for 1/2 of the other oils.

  • These are SO GOOD. They’re fluffy and delicious and are 20x better if you warm them up just a little from room temp. We found a gigantic zucchini the size of small child hiding away in our garden (oops) and found that while they are too bitter for sautéing, they’re perfect for muffins! I doubled the recipe, made a summer vegetable soup, and still have a pound over. May have to make more muffins at the rate we and our friends are devouring them haha. Thanks for another delicious recipe!

  • My 2.5 year old helped make these and only *slightly* questioned the quick dump of the zucchini — which she promptly forgot about when she ate them. 😉
    We were actually out of regular flour and ended up substituting coconut flout and they still turned out great ( though not as fluffy as the pics.) Might try almond flour next time as an added bit of protein. Great recipe, thank you!

  • These were real “boy bait” in my house! My son even took a plate of them to his buddies and they were gone in minutes! Chocolate chips are still very new in Germany where I live and, hence, very expensive: So I chopped up chocolate and stirred it all in at once. I didn’t press in the pieces onto the top. It worked fine and they tasted fantastic!! I was worried about filling the muffin cups so full, but it there was no overflow. Trust you, Jenn, to know how to do it!

  • Good muffins. Great flavor with the zucchini and chocolate. Eat your veggies in a muffin – gotta love that! Next time I’ll try mini chocolate chips. The regular size chips were just fine and looked pretty on the top, but I’m thinking the minis might distribute better throughout the batter and provide a more consistent chocolate ratio within the structure of the muffin.

  • Jenn, loaf pan, size, baking temperature and time.. Thanks, Carol

    • Hi Carol, I’d bake it at 325-degrees in an 8 ½” x 4 ½” loaf pan. Start checking it for doneness at about 45 minutes (but it may take as long as 60). I’d love to hear how it turns out!

  • My 5 yo daughter, who refuses to eat anything green, gobbles these up. I did peel the zucchini, to remove as much green as possible, and grated them on the fine side of my box grater. My 8 yo son says they need more chips on the inside and less on top for better chip to muffin bite distribution. Other than that, another winner recipe from Jenn!

  • Easy to make & tasted great – kids loved them. A great addition to the lunchbox. I used mini dark chocolate chips to reduce messiness on little hands and faces. 🙂

  • I added peanut butter chips to this fabulous recipe. My very picky 4yr old has been eating them for breakfast for the last 3 days.

  • These are simply delicious!
    What a perfect snack for kids who don’t think they want vegetables.
    A keeper!

  • These were delicious and easy to make. I substituted 1c of whole wheat flour. My boys loved them. They couldn’t even taste the zucchini.

  • These muffins were wonderful! I did not add the chocolate chip and they were still seeet and tasty.

  • These muffins were great. I made them exactly as the recipe stated, and they were really easy, delicious and not too sweet, which I liked. Thanks!

  • I don’t usually like chocolate in my zucchini muffins, but these were delicious! Not too sweet, just perfect and easy.

  • Wasn’t sure my kids would like these but they gobbled them up. Great recipe!

  • I’m using a very large zucchini from my garden. How many cups of shredded zucchini is needed for this recipe?

    • Hi Fay, You’ll need about 1 and 1/3 cups. Hope you enjoy them!

  • Thanks for all of your wonderful recipes. Just wondering if you could swap vegetable oil for the butter.

    • Yes that will work, Kathy. Please let me know how it turns out if you try it that way!

  • How would I adjust if using a mini muffin tin? Thank you!!

    • Hi Susan, I’d start checking for doneness around 12 minutes.

  • Looks Yummy as usual !!! Can’t wait to try these….We really do appreciate what you do…Thank You !!

  • This looks good. Should I apply oil on muffin tray before adding the batter?

    • Definitely – I use a nonstick cooking spray. Makes it easy 🙂

  • I can’t wait to make these! Would it work to make the batter the night before, refrigerate, and bake in the morning before school?

    • Hi Molly, It’s best to bake the batter right away so the leavening agents don’t lose their oomph. The muffins are quite moist, so it’s perfectly fine to bake them the night before. Hope that helps!

  • Love your recipes, always a treat to have recipe show up in email. Question, I read where you can use spirilized veggies in place of grated, have you tried this technique?

    • I haven’t, Margie, but I think it’d work as long as the spirals aren’t too thick. You might just chop them up a bit if they are long.

  • I have a really large Zucchini and want to know how muc h 9 oz is in cups.

    • It’s about 1 and 1/3 cups. Enjoy!

  • Is there anything I can substitute for the chocolate chips? Pecans maybe, and how much?

    • Hi Arlene, Currants or raisins (in the same amount) would also be good.
