Chocolate Zucchini Muffins

Moist and healthy Chocolate Zucchini Muffins with chocolate chips (of course!), a few other sneak ingredients (yes, yes), and tender crumb are the mid-month treat we need right now. Their wholesome ingredient lineup speaks to all things healthy + January + I want to eat this all the time, so let’s behave. Their decadent, fudgy texture screams treat yo self + I’ve been good long enough + chocolate for breakfast makes life better, so let’s do it.

I originally shared this recipe to celebrate a big-time blog milestone (5 YEARS of blogging. Update: we are now approaching 7, eek!). I’m resharing today because these Chocolate Zucchini Muffins are so very perfect for the January mid-point.

We’re removed enough from the holidays for the reality that the next “free” day off isn’t until end of May is settling in. The healthy eating mantras we set on January 1 are feeling decidedly less decided. We’re busy and we’re hungry and does eating a healthy muffin for breakfast make any difference anyway?

Yes, it does. And yes it can be delicious! Case in point: Chocolate Zucchini Muffins. They’re whole wheat, naturally sweetened with honey, and when you start your day with one, you’ll feel like you’re a part of a super special club.

The tasty chocolate for breakfast, I eat healthy and it’s happy, homemade muffins are the best muffins club!

Chocolate Zucchini Muffins–A Healthy Muffin Recipe for a Happy Day

When I first shared this Chocolate Zucchini Muffins recipe on my 5-year “blog-iversary,” I spent a long time deliberating what kind of recipe to share. I wanted it to feel representative of both my overall recipe point of view AND of the recipes I know that you, my wonderful readers, love most.

Answer: MUFFINS!

But not just any muffins. These muffins needed to be indisputably delicious while still using wholesome ingredients. I wanted them to taste rich and satisfying but still be fit for a healthy breakfast. Also, chocolate. We need chocolate.

Although this is a mostly “healthy” food blog, to me healthy doesn’t mean sticking to a specific diet, giving up favorite foods (chocolate forever ♥), or blowing your budget on fancy ingredients.

I firmly believe that healthy eating can (and should!) be just as satisfying as the alternative, if not more so. A healthy, balanced diet will help you lead a more energetic, balanced life, and it can be SO YUMMY too. I delight in creating more wholesome versions of everyday comfort foods, and muffins have been some of your absolute favorites.

A few dietary considerations and recipe notes:

  • Chocolate Zucchini Muffins, Gluten Free. I’d suggest swapping a gluten free 1:1 baking flour like this one.
  • Chocolate Zucchini Muffins, Calorie Count. Considering the healthy fats in these muffins, I find the calorie count reasonable, but if you’d like to reduce it, you can omit or reduce the amount of chocolate chips.
  • Chocolate Zucchini Muffins, Vegan. For this adaptation, use a non-dairy milk. You’ll also need this recipe to be Chocolate Zucchini Muffins, no eggs, so I’d suggest a flax egg (not yet tested, but I believe it would work!).
  • Chocolate Zucchini Muffins, Keto. This is one I’m afraid I can’t comment on, since I don’t follow a keto diet. I believe you will need to use an alternative sweetener, so I’d suggest looking for a recipe that is already designed this way. (The avocado, however, should be keto friendly!)
  • About That Avocado. The avocado makes the muffins ultra moist, and its taste is super duper subtle. I hardly noticed it, and a few of my friends make them routinely for their kids, and the kiddos don’t notice it either.

I truly wish that we could all squeeze into my kitchen so that I could serve you a Chocolate Zucchini Muffin, warm from my oven with the chocolate chips still melty on top, and do my best to tell you in person how I am abundantly, fiercely grateful that you are here.

When I began this website, I barely knew what a food blog was, let alone that it could be an actual job. If you had told me back then that if I stuck with blogging long enough and worked hard enough that other people—people who were not my mom, grandma, or Ben’s aunt—would read it and even make my recipes, I would have stared at you like you had two heads.

If you had told me that I’d eventually leave my very stable consulting job to pursue blogging as an actual career in which I would earn an actual income, I would have stared at you like you had three.

Although we are separated by a computer screen, that doesn’t change one ounce of how much I appreciate you. Thank you so much for being here, for putting up with my life stories and overuse of alliteration, and for bringing recipes like these Chocolate Zucchini Muffins to life in your kitchen.

You make this little corner of the internet (and therefore this recipe!) possible. Cheers to you, to Chocolate Zucchini Muffins, and to many more healthy muffin recipes to come!

Recommended Tools to Make Chocolate Zucchini Muffins

  • This brilliant muffin tin: It’s durable, easy to clean, and comes with a lid so that you can easily transport the muffins too.
  • Coarse grater: Easiest for grating a small amount of zucchini. (For larger amounts, I like to use the grater blade on my food processor.)

Chocolate Zucchini Muffins with Avocado

Yield: 12 muffins
Prep Time:
20 mins
Cook Time:
15 mins
Total Time:
40 mins
Healthy Chocolate Zucchini Muffins. Moist, tender muffins made with avocado, whole wheat flour, and chocolate chips. You'll never taste the veggies!


  • 1 cup very finely shredded zucchini — about 1 small/medium zucchini
  • 1 medium avocado — peeled and pitted
  • 2 tablespoons coconut oil — melted and cooled to room temperature (or substitute light extra-virgin olive oil or canola oil)
  • 1 large egg — at room temperature
  • 2/3 cup coconut sugar — or substitute granulated sugar
  • 2 tablespoons milk — any kind you like (I use unsweetened vanilla almond milk)
  • 1 teaspoon pure vanilla extract
  • 1 1/4 cups white whole wheat flour
  • 1/2 cup unsweetened cocoa powder
  • 1 teaspoon baking soda
  • 1/2 teaspoon cinnamon
  • 1/2 teaspoon kosher salt
  • 1/2 cup semisweet chocolate chips — mini or regular


  1. Preheat your oven to 375 degrees F. Coat a 12-cup standard size muffin tin with nonstick spray. Set aside.

  2. Spread the zucchini out on a few layers of kitchen or paper towels. Press out as much water as possible, changing out the towels as needed. Set aside.
  3. Place the avocado in the bowl of a standing mixer fitted with the paddle attachment or a large mixing bowl. Beat with the mixer until the avocado is very smooth and no chunks remain. You should have about 2/3 cups of smooth avocado paste. Add the coconut oil, egg, coconut sugar, milk, and vanilla extract, beating until well combined.
  4. In a separate bowl, stir together the white whole wheat flour, cocoa powder, baking soda, cinnamon, and salt. Gradually add the dry ingredients to the wet ingredients, folding by hand with a wooden spoon or spatula and stirring just until the flour disappears. The batter will be very thick, almost like brownie batter, and the dry ingredients will take several strokes to work in between additions. Fold in the zucchini and chocolate chips, reserving a few of the chocolate chips to sprinkle on top of the muffins.
  5. Scoop the batter into the prepared muffin cups, filling no more than three-quarters of the way to the top. Sprinkle with the remaining chocolate chips. Bake for 15 to 18 minutes, until the tops are set and a toothpick inserted in the center comes out mostly clean with just a few moist crumbs clinging to it. Let cool in the pan for 2 minutes, them transfer to a wire rack to cool completely.

Recipe Notes

  • Store leftovers at room temperature according to my guide for How to Store Muffins for up to 5 days or freeze for up to 3 months.
  • If you would like to reduce the calorie count of the muffins, omit or reduce the number of chocolate chips.

    • Melissa, I am almost tearing up reading this, thank you! These are such kind words and they really mean a lot to me. I truly couldn’t blog without wonderful readers like you!

  2. Happy blogiversary! 

    I just recently came into your blog and have truly enjoyed the recipes, articles and sense of humor! Thank you! 

  3. Awww Erin, happy blogiversary!! :) I honestly remember one of your first posts and it’s so incredible to see how much your blog has grown! These muffins are the perfect kind of recipe for a celebration! Cheers to you!

    • Marina, I can remember you commenting on those early posts! Your ongoing support means so, so much. Thank you, and I’m so glad that we got to e-meet through blogging :-)

  4. Thank YOU for the kind comments – I’m sure that I’m not the only one who appreciates the hard work that goes into creating such wonderful recipes that are also healthy. I’ve tried many of them (the Irish Soda Bread Muffins are the greatest!) and am pleased to say that my husband also likes the recipes I’ve tried.
    Happy 5th. and keep up the good work.

    • Chris, thank you for reading, for trying my recipes, and for helping me do what I love every day. It means more than I can say!

  5. Happy blogging anniversary, Erin! I had a job interview last week, and during the “get to know you” portion of the interview, they asked me what my favorite website was. I told them the honest answer: your blog! You have helped so much since I graduated college last year and wanted to start cooking for myself but maintain a healthy diet. Your recipes are always approachable and delicious, your writing is delightful to read, and the updates about your life always make me smile. I am so grateful that I found your blog. Keep doing what you do, because you are so appreciated. <3

    • Annie, you just MADE MY DAY. Thank you!! I can’t say how much this means to me. Knowing that my recipes come to life in your kitchen and that they are helping you enjoy healthy meals is what motivates me more than anything else. Thanks again!

  6. Happy five years Erin, that’s amazing, and love following your journey :)

  7. Erin, do you think I could sub a GF flour blend (Bob’s Red Mill 1 to 1)?

    Thanks! These look so yummy! Love zucchini!

    P.S. Happy 5 Years of Blogging :)

    • Lauren, I have never tried a 1:1 GF blend in a muffin recipe, but if you’ve been happy with how it’s worked for muffins in the past, then I think that would work just fine!I hope you love the recipe (and thank you!!)

  8. Congratulations on your five ‘blogversary’! Your blog is beautiful and you couldn’t choose a better recipe to celebrate. The pictures are wonderful! Keep on the good work!

  9. Congratulations on your five years and many more Erin! I love your blog, your recipes, your style, your writing and everything about this blog. Keep up the good work!!!

  10. Happy blog anniversary! These look amazing Erin!

  11. Congratulations on 5 years of blogging!  I have a number of your recipes that I make with some regularity, so I appreciate that you share them with us.  Even though I rarely bake, I’ve saved this muffin recipe, because they’d make a very nice snack (…and my husband who doesn’t appreciate avocados would never know there was avocado in them…)

  12. Congrats, Erin! You have a beautiful blog and great recipes! Like these muffins! I can’t believe I haven’t made any muffins yet. I think I will start with your recipe as those muffins look perfect to me!

  13. Congratulations on five years of awesome contribution to the blogosphere! :) Thanks for all of your hardwork and fun posts, not to mention your insanely good recipes.

  14. Happy Blogiversary Erin! I loved your blog when I discovered it 3 years ago or so because I loved to read and support a local Madison blogger. This is one of my go-to blogs when I’m looking for a new recipe to try, along with the many favorites I already have (not surprisingly, many of them are muffins.) I’m excited to see what you have in store for us in year six!

  15. I’ve only been with you for a year (or two), but I LOVE reading your blog (you’re pretty funny!) and the recipes of yours that I have tried…very DELICIOUS! Happy 5th blogiversary! I love making good things to eat, but I’m not so good at creation, which is why I totally appreciate the ones who create! Keep up the great work! I’m going to make these muffins to take to my son this weekend!

  16. Hi Erin! Congratulations! I don’t know how you do it – keeping us entertained as well as healthy and well-informed about how to bring good foods to life! Thank you for the joy you share and have shared for the last five years (it is contagious)! I look forward to each and every post! Hope Ben will take you OUT for dinner tonight!!! You deserve a break!!!

    • Laurie, you are the sweetest! Thank YOU for your ongoing support over the years. I can’t say enough how much it means! And confession: we are eating leftovers for dinner tonight (recipe I photographed earlier today), but I am sure that there will be a glass of wine to go along with them :). Have a wonderful evening and thank you again!

  17. So proud of you. xoxo

  18. Happy blogging anniversary, Erin! Congratulations!

  19. These sound wonderful and I can’t wait to make them. I love that the amount of added fat is so low. Congratulations on five years of blogging. I have made several of your recipes since finding this blog and they have all been wonderful.

  20. On my list to make this week! Had your lemon basil one pot chicken dinner last night and your chocolate chip pumpkin bread is in heavy rotation around here. I always look forward to your emails and I don’t think there’s one I haven’t pinned. Your recipes are fantastic. Happy blog anniversary and thanks for your creative energy and deliciousiousness too.

    • Sherrie, THANK YOU! This comment is a joy to read. I can’t say enough how much it means to know that you enjoy my recipes. And now I am craving that pumpkin bread :-)

  21. Fantastic muffins! And congratulations on 5 years. I am just about to reach 2 and I think that is a big deal, lol. So I very much admire that. And yes, food blogging 5 years ago would have been something that is not in the norm, and it is hard to strongly commit to it when other people don’t see the point. But that is starting to change now because of committed, hard working bloggers such as yourself. So thank you for sharing this (:

  22. I was thinking we should pay a little bit of homage to “The Law Student’s Wife!” I didn’t think I’d ever get used to the new name, but I certainly have! It is nice that Ben is no longer a law student and you are not married to a law student anymore, but to a full-fledged attorney! I know you started it as a hobby and something to keep you busy while Ben was toiling away at school and the library! And, look what you’ve created! Awesome!

  23. Hey Erin! Congratulations!!

    These look amazing. Any good substitute for egg for these? My son is allergic but love to make things with hidden veggies. Thank you! 

    • Angela, I’ve never tried this recipe with a flax egg, but if you have had success with it in other muffin recipes, then I think it would be worth experimenting. If you do decide to play around and try it, I’d love to hear how it goes.

  24. Erin, you are one of my “every day” blogs that I read, re-read and remember as I’m planning meals, healthy, delicious, sometimes decadent treats and when I’m in the mood to live vicariously thru your travels. ? Thank you for making my kitchen adventures more sweet, savory and satisfying! PS, just made Banana Walnut Muffins AGAIN — the best!

    • Marina, I can’t say enough how much this makes me smile! Thank you so much for reading my blog and for your support. And those muffins are some of my absolute favorites too!

  25. Congratulations Erin on your 5th anniversary of blogging!! I’m a quite new comer to your blog about 2 years and have been loving it! I love your healthy approach. These Chocolate Zucchini Muffins with Avocado look awesome! I have never tried baking with Avocados so I am definitely going to be making these. Looking forward to many more years of reading your blog and recipes!

    • Kristen, thank you so much! It really means a lot to me to have you as a reader of my blog. I hope that you love these muffins. Avocado is really wonderful in baking because it makes things so moist and is healthy too!

  26. Shawnna Griffin Reply

    hey girl- congrats on your 5 years! Love ya!!!

    • Thank you so, so much Shawnna! And thank you for your wonderful comments along the way. I can’t say enough how much it means to me!

  27. These muffins are really good! I only had two-thirds of an avocado, but I added a splash more milk and olive oil to compensate. I got 10 gloriously tall, domed muffins, and they’re delicious!

    • I am so excited to hear that Caitlin! Thank you so much for trying the recipe and for taking time to report back. I really appreciate it!

  28. I made these today and they were incredible. I am new to your site, but have already pinned loads of recipes! Cant wait to try more

  29. Hi! Any healthier way to replace the sugar? Applesauce perhaps? Thanks can’t wait to try them!

    • Hi Debby, I can’t recommend this as the muffins are not very sweet to begin with. You could play around with using a little maple syrup, but it’s more liquidy, so you’d need to cut down on liquid elsewhere—it’d definitely be an experiment! If you’re interested, these blender banana oatmeal muffins are sweetened only with honey.

  30. So yummy!! I love that I can feel good about feeding these to my kid when we need a little chocolate fix. I substituted 1 cup of almond meal and 1/4 cup of coconut flour instead of the whole wheat flour and the consistency was perfect! I made 24 mini muffins and baked for around 10-11 minutes. Will definitely make again!!

  31. These turned out amazing. It was my first time baking with avocado and I was really surprised by how moist and decadent these little muffins turned out. They are definitely more of a brownie like texture than a “muffin” but so good for how healthy they are. I added some 1/2 tsp of ground cloves to kick up the spice factor and swapped 2 tbsps of flour for cornstarch. I ended up baking my muffins for an additional 4 mins than the suggested baking time (probably because my batter was a bit too wet) but these turned out so delicious. I can’t wait to try out the other recipes on your site. I already bookmarked the healthy blueberry muffin recipe and the Irish soda bread muffin recipe ;)

    • HOORAY, I am so so glad to hear it! Thanks for taking time to leave this wonderful review too!

      • No problem! I also wanted to say I appreciated that you described the texture of the batter, and noted alternative ingredients in the recipe directions. Those two things really helped make this a successful recipe.

  32. These turned out so rich and fudgy, my kids had no idea hey were eating vegetables, too!

  33. SO delicious! They certainly don’t taste “healthy,” but I don’t feel guilty going back for seconds!!

  34. I love the addition of zucchini in these muffins! You can’t taste it but it adds great moisture!

  35. These quickly disappeared in my house! They taste so good!

  36. These muffins are such an easy way to incorporate veggies into our diet. They were so good.

  37. We loved these!

  38. AND avocado! In love with these muffins!

  39. This recipe has helped our family! We want to eat healthier but love chocolate!! Problem solved :) :)

  40. Happy blog anniversary! A good friend of mine told me about your blog and once I read several recipes of yours I became a follower. I always look forward to the recipes you share with us. Using zucchini would keep these muffins nice and moist just as in zucchini bread. The addition of chocolate got my attention. I will have to make these soon.

    I can not say enough about these muffins. Actually mine ended up being bread because I oddly do not own muffin tins. I  was skeptical when trying this recipe because I thought “how could this possibly be good?” But hey, chocolate. To my delight, this recipe was super duper easy to make and I could not have just one after I tried my first. 

  42. Hi Erin any advice on what to substitute for avocado? It’s pretty expensive around here. I’ve thought of applesauce  and pumpkin. how much do you think would be required?

  43. Hi Erin after your reply I made it with avocado and I absolutely love these. I try to minimize sugar so I halved the sugar content and they turned out delicious  and much more suitable for breakfast. The fudgy rich texture makes you think you are eating a brownie. Thank you for yet another faboulous baking recipe and I hope you continue is to sneak more avocado in them!

  44. First, I want to start by saying I can’t ever remember posting on a food blog – – but these muffins! Wow. So delicious and – – dare I say it: DECADENT! I swapped the granulated sugar for 1/3 c honey and did 1/2 c oat flour and 3/4c all purpose. The results are on point: a muffin that satisfies my chocolate cravings AND I don’t need to feel guilty about! Thanks!
