Let’s rewind to a housewarming party earlier this summer. Late that night, a girl walked in with a warm-from-the-oven zucchini cake covered in cream cheese icing. She set it down on the counter along with some forks and tipsy partygoers, myself included, eagerly dug in.
Upon first bite, I declared it the best cake I’d ever had. It didn’t even taste like zucchini—it was just the most moist, delectable spiced cake I had ever tasted. After the second bite, I pronounced that I would henceforth define my life in terms of the pre-zucchini cake era and post-zucchini cake era. It was an enlightening experience, friends.
Fast forward to last week, when I was contending with a serious chocolate craving. I tried to satisfy it with a small piece of dark chocolate, which usually does the trick. When that failed, I ate a chocolate chip cookie. That didn’t cut it, either. I nibbled on chocolate this and chocolate that, but my craving was fueled by deadline stress and only a seriously decadent, rich chocolate treat would do. Enter zucchini brownies.
I found a zucchini brownie recipe that called for honey instead of sugar and whole wheat pastry flour instead of all purpose. I took it as an opportunity to bake with some new ingredients in my pantry, substituting some whole spelt flour for the pastry flour and coconut oil for the vegetable oil.
I was slightly concerned that the combination of zucchini, honey, coconut, chocolate and cinnamon flavors would overwhelm the taste buds, but they melded together perfectly.
Once I had mixed together the healthiest brownie batter around, I dumped in an entire bag of dark chocolate chips.
Chocolate craving: satisfied.

Decadent zucchini brownies made with whole wheat and dark chocolate chips. So rich and moist, you’ll never want to go back to regular brownies!
Ingredients
- 2 cups zucchini, grated
- ½ cup melted coconut oil
- ½ cup honey
- 2 eggs
- 1 teaspoon vanilla extract
- 1 cup whole wheat pastry flour
- ¾ cup whole spelt flour (or an additional ¾ cup whole wheat pastry flour)
- ½ cup unsweetened cocoa powder
- ½ teaspoon salt
- 1 ½ teaspoon baking powder
- ½ teaspoon cinnamon
- 1 ½ cups (12 ounces) semi-sweet or dark chocolate chips (I used a bag of Ghirardelli 60% Cocoa Chips)
Instructions
- Preheat oven to 350 degrees and grease an 8 inch square baking pan.
- Grate zucchini. Dump into a mesh colander and squeeze it with a towel to get rid of excess moisture. Fluff it back up with a fork.
- In a large bowl, beat together the wet ingredients (oil, eggs, honey and vanilla). Stir in the zucchini.
- In a separate, smaller bowl, stir together the dry ingredients (whole wheat pastry and spelt flour, cocoa, salt, baking powder and cinnamon).
- Pour the dry mixture into the wet/zucchini mixture. Stir just until combined, and then stir in the chocolate chips.
- Pour the batter into your prepared pan.
- Bake 30-35 minutes or until a toothpick inserted in the center comes out clean (mine was done baking at 30 minutes). Let cool completely.
Notes
Adapted from A Dash of Sash.
Make it dairy free: Use your favorite dairy-free chocolate chips instead of regular chocolate chips!
Preparation tips: I have tried making these brownies with agave nectar instead of honey, but they tasted bittersweet. Honey is best.
Serving suggestions: My friends raved over these brownies when they were fresh from the oven. I preferred them at room temperature or chilled, so the chocolate is not gooey but a rich, dense contrast to the super moist crumb. Either way, you’ll love them!

P.s. Upon closer inspection, I realized that this is the same brownie recipe that Kelsey from Happyolks adapted for her blackberry zucchini brownies. Her recipe goes to show that you can substitute fresh fruit for the chocolate chips if you’re not craving such an intensely chocolately treat.
Caroline
Woah. Chocolate and vegetable cravings cured! :-) These look incredible Kate!!!
The Fauxmartha
I could totally eat these and still feel good about my sweet tooth self. Dark chocolate zucchini brownies—yes, please!
zazzie
Sounds amazing! Can’t wait to try:))
Would it hurt the taste a lot if I added some other oil instead of the coconut oil you suggested? Do you have any suggestions maybe? Unfortunately I don’t know where they sell such things..
Love your blog – in case it wasn’t obvious already;)
kate
The original recipe called for olive oil, but I would probably go with vegetable oil for its neutral flavor. I’ve found coconut oil at health/gourmet stores, but it can be a little pricey. So happy to hear that you love my blog, Zazzie!
zazzie
:) Thank you
kate
If these taste as half as good as they look…im hooked. :) Lovely!
Kelsey
Great minds think alike. We know a good recipe when we see it! The Blackberries give it more of a fudge like texture, I must admit. The chocolate chips keep the brownie authentic :)
Kimberley
I am so into this!
Lena
I really want to make these right now. They sound delicious, and the pictures are great!
dana @ my little cel
Yum! These look fabulous, friend! How creative!!
Sandra
This looks so yummy!

Devine! Love this idea :)
genevieve
These pictures are just. not. fair. These look amazing! And you’d never know they have zucchini in them from looking at ’em! Yum.
kickpleat
Those brownies look so good! I’ve been eating a ton of zucchini lately but keep forgetting to save some for baked goods and this one looks like a keeper. I LOVE your mint green spatula!
kate
Thanks! I hope you can make zucchini brownies before zucchini season ends. Couldn’t resist that green spatula when I saw it at T.J. Maxx. :)
chinmayie
Looks great Kate! I have seen so many zucchini brownie recipes that I really want to try it! Yours looks very healthy and delicious!
Hillary {Nutrition N
off to the store to get chips to make these STAT!
Andrea
Ok, these look fantastic! Beautiful photography also!
Jessica
Finally made these this weekend. They have been calling me. So delicious and your recipes are so easy to adapt to gluten-free.
kate
I’m so glad to hear that! Is it because they’re made with whole wheat?
Andrea
Hey! I ended up making these and putting them on my just-started-up blog! Linked back to here, of course. LOVED them. Thank you!
Flaminia
I live in Italy, and made these for a dinner party… They ate the whole pan! The Italians were shocked by who healthy they were (once I told them the ingredients). They were so tasty! thanks!!!
Ashton
I’ve made a zucchini brownie recipe very similar to this before, but it calls for baking soda instead of baking powder. Does the baking powder make them more cake-like?
kate
That’s a great question, Ashton. I am really not sure. I’ll try it with baking soda instead next time, because I think I would prefer for the brownies to be a little less cake-y. I’m hoping that chopping the chocolate rather than using whole chocolate chips help make them more uniformly fudgy, too.
Sara
Kate! These were delicious!! Thanks for the recipe!
Kate
Glad you enjoyed the brownies, Sara! I’ve been meaning to make another batch with finely chopped chocolate instead of chocolate chips. We’ll see!
Linnea
My attempt to google to find a recipe with chocolate, zucchini, and a liquid sweetener led me to this recipe, and I’m so glad it did! I used your recipe as a spring board for a vegan zucchini brownie and it worked out great (and then I blogged about it :P)! Thanks for sharing!
Kate
Awesome, I’m glad the recipe worked well for you!
bonnie schmitt
Hi Kate, I can’t wait to make these tonight! Do you think adding some walnuts would mess with flavors at all? I love nutty brownies and since walnuts are mild in flavor I thought the additoon of them would add a nice crunch. What do you think?
Kate
Hi Bonnie, I think that adding walnuts is a great idea! You might also chop up the chocolate chips some so they melt into the brownies a little more uniformly. Please let me know how they turn out.
bonnie
Hi Kate, so the walnuts were a success and I made my hubby a believer of zucchini brownies! I tried chopping the choc chips and used 1/2 tsp baking soda and they came out moist and oh so gooey! My batter did end up being a little thick so I added a splash of milk and a little more coconut oil.
Kate
Thanks for getting back to me, Bonnie! I’m happy to hear that the brownies turned out well. I’m definitely going to chop up the chocolate next time.
Shaweta
Hi Kate,the brownies look awesome and the most important it is healthy. I can’t wait to try this wholewheat zucchini brownie tonight . I will let you know how it turns out.
Denice
I’m excited to try these but I don’t have enough honey on hand for the recipe. Any suggestions for how much turbinado and/or brown sugar to use as a substitute?
Ranie
Hi! This recipe looks AWESOME! And, this may sound goofy, but… What size pan? It looks like you’re using an 8×8 or 9×9… Thanks! <3
Kate
Hey Ranie, I used an 8-inch pan for the brownies. A 9-inch pan would be fine as well, but it might finish baking a few minutes faster.
Sarah
Wow these are incredible! Thank you so much for this recipe! I made them last night and used all spelt flour because it’s all I had and it turned out delicious! The dark chocolate chips are the way to go!..I’m actually eating some brownie as I type this…you want to make these!
★★★★★
Kate
Thank you, Sarah! So glad you enjoyed the brownies.
Caroline
These look great, about to make them. Do you think these would work in a mini muffin pans to create brownie bites?
Kate
Probably! I haven’t tried it, though, so I can’t suggest baking times.
Caroline
Ok well I tried in the mini muffin pan, they came out OK. I think I could perhaps cut out the baking powder, they were more like mini muffins vs. mini brownie bites. Also, I found them to be a bit “whole-wheaty” tasting, (used 1 3/4 cup WW pastry flour). But all in all, they were pretty good, just need some tweaking. I will for sure try again but stick to the 8×8 pan to compare! All your recipes are great!
Caroline
I baked for 10-12 mins and filled the muffin tins up to about 3/4 full – they made about 30 mini muffins.
heather
would cacao powder would as well?
Kate
I’m so sorry for my delayed response, Heather. I *think* it would work, based on this article, but the comments are worth reading: http://www.thekitchn.com/-good-questions-243-148454
Helaine Winer
Just made these and they are awesome. Fed them to my daughter and her boyfriend (he’s a pretty picky eater and we didn’t tell him about the zucchini) – they loved them.
Wondering if the coconut oil, honey, zucchini combo can be used for most recipes instead of butter, sugar, egg??? Would love to adapt favs like – tollhouse cookies, etc.
Thanks so much!!!!!!!!!!!
Kate
Thanks for commenting, Helaine! I’m so glad you enjoyed the brownies. I’ve been experimenting quite a bit with coconut oil and honey, though I haven’t done much more with shredded zucchini. Usually you have to reduce the other liquids to account for the additional moisture in the honey. Coconut oil is generally a good 1:1 substitute for butter in baked goods. You might also like my banana bread recipe and gluten-free chocolate chip cookies!
Nicole
Hello – Our family loves your recipe’s (even the 3yr old)!
To make this gluten free, do you recommend using all spelt flour?
Thx –
Nicole :)
Kate
Hey Nicole! I’m so glad you’re enjoying the recipes! Spelt flour isn’t actually gluten free… although some people with gluten sensitivities find it easier to digest. I’m not sure what to suggest other than an all-purpose gluten-free flour blend.
Samantha Dew
Hi all, has anybody substituted the two flours in this recipe for buckwheat flour at all? Would this work?
Thank you,
Sam
Kate
Hey Sam, I’m sorry, I don’t know if anyone has. Buckwheat flour is gluten free so it may be tricky to get the same texture that you see in the photos.
Shani
Thsee look great! Do you know the calorie counthe per brownie?
Kate
I’m sorry, Shani, I don’t. I don’t provide nutrition facts because they vary widely depending on actual ingredients used and serving size.
Kristin
Oh please tell me if you think they’d be yummy withOUT the chocolate chips? I was just given a mammoth zucchini for my birthday today and I want to make them for my parents’ anniversary tomorrow…alas, no time for a shopping trip – what do you think?
Kate
Hey Kristin! I bet they would be tasty without the chocolate chips. They just won’t be as rich.
Kristin
Thanks Kate!
Ok so I made them with canola oil, half white flour, baking soda instead of baking powder, and because I was out of chocolate chips I sprinkled a generous portion of mini m&ms on the top before baking. They turned out like chocolate cake and nothing like brownies. My kids liked them, husband and mom not so much. My aunt who doesn’t like sweet things loved them.
I think they definitely needed the chocolate chips for the rich factor. That being said, by tomorrow there will not be a crumb left!!
Thank you for a healthy & yummy recipe! Can’t wait to try it the way it is written. :)
Kate
Interesting! I’m sure you’re right about the chocolate chips. The cakey texture could also have to do with the baking soda, not sure.
Jessie
This may be a silly question, but would these need to be kept refrigerated? I would love to include these in a ‘healthy treats’ gift basket I’m putting together, but they would be at room temperature for a while.
Kate
Hey Jessie! These brownies are pretty moist so I wouldn’t leave them at room temperature for more than a day.
Jessie
Thanks : )
Amanda
Kate- I just wanted to say how much I’ve enjoyed exploring your blog and cooking exploits! It’s so nice to know that if I’ve got the time to cook I’m sure to find something healthy and enjoyable here. Made these brownies this evening and can’t wait to enjoy. Thank you so much for sharing your passion!
Kate
Thank you so much, Amanda! Hope you loved the brownies. I’m glad you found my blog!
Bryony
I made these with grated squash instead of zucchini and they taste amazing. also used spelt flour which did not really rise but they still look and taste great! Always looking for ways to use my coconut oil and have no refined sugars in my recipes (to satisfy my partner’s sweet tooth!) Thank you :)
★★★★★
Kate
Thanks, Bryony! Glad you enjoyed the brownies! You might like my banana bread, too!
Abi
Thanks for all the great recipes Would love to try this one. Do you need to take the outer skin off the zucchini (courgette to me,) or can you just grate the whole thing? Loving your blog over here in London!
Sonali
Your blog is amazing! I am a carnivore, but enjoy your vegetarian recipes. And your desserts look amazing. I cannot wait to make this, as well as the citrus olive oil cake and almond-cardammom-pistachio cake. One question about these brownies – what other flours could I use instead of spelt? I don’t have any and don’t want to buy a whole pack, since I might not end up using the entire thing. Could I just use just white whole wheat flour or part WWW and part almond flour?
Sonali
Never mind, I just reread the ingredients, and see that you’ve noted that the spelt could be excluded!
Suprita
Hi Kate! Can you use regular whole wheat flour for these brownies?
Belsante
How many whole zucchinis did you use?
Sukhmani Thind
I made this recipe for my family and they loved it including my very picky brother. My dad loved them so much that he asked me to bake him these brownies for his birthday instead of a cake. You’re website if filled so sooooo many great recipes. I love them.
★★★★★
KP
Hi Kate, this recipe looks delicious! Do you know what I could substitute instead of the honey while still keeping them healthy? I’ve been reading that heating/ baking with honey changes the chemical properties of honey, making it not really good for you at that point. I still can’t figure out what a healthy “sugar alternative” is. :(
Kate
Hey KP, someone mentioned that the other day but I was totally unable to find documentation to back it up. Maple syrup would probably work fine.
Amy
These were amazing! I only had regular whole wheat flour, and they were more cake-like but still delicious. Satisfied my sweet tooth without being sickeningly sweet.
★★★★★
Kate
Great! That’s so good to hear, Amy. Thanks!
Barrie
I wanted to try a “no sugar” version – so took out the chocolate chips and subbed-in cocoa nibs. Added walnuts. Used the ww flour I had on hand (no spelt flour). My result I would call a cake rather than a brownie. Twice as high and “fluffy” as a brownie, but it’s good.
★★★★
Kate
Great! I’m glad it came out well, Barrie.
Aga
Dear Kate, do you think it’s possible to make these brownies without eggs and use flax seeds instead? Thank you!
JTM
Just tested a vegan version of these today by replacing the eggs with flax eggs and honey with maple syrup. For some reason, the coloring of my brownies came out dark brown like normal brownies versus the light brown blondie look of Kate’s. Not sure why. In any case, the texture came out fudgy/spongy. So, if you like that, then you’ll like these! I also had to gauge the baking time by feel since a toothpick would come out clean very early on when it’s not actually done baking. When the center felt decently firm, I took the pan out to cool.
Catalina
Hi Kate!This recipe looks so good! I don’t live in the US and I haven’t found any whole what pastry flour in my country. Can i use whole wheat flour or regular pastry flour instead? Which option is better?
Kate
Hi Catalina – You can use regular pastry flour, it will just change the nutrition content and not be quite as healthy. Let me know how it goes!
Rebecca
Just tried these out today, and I’m hooked! Everything I love about zucchini bread meets everything I love about brownies. The perfect cure for college stress…that won’t make me more stressed when I think about my sugar consumption.
★★★★★
Kate
Hooray! Try not to stress too much :)
Anne
If I were to substitute regular AP flour(Or cake flour) would I change the amounts?
Kate
Hi Anne, all-purpose flour should work fine in equal amounts (I haven’t tried to verify).
Caitlin
Hi, I always use just AP flour (no spelt) when I make these, and they always turn out great. I’ve been using this recipe for five years now!! My favorite brownies.

Karen G
Oh my goodness! Chocolate craving crunched! Amazing! I squeezed a bit too much from the zucchini, so mine were a tad dry. That didn’t stop me from eating them. Next time I’ll read the recipe more carefully.

I’m glad they still tasted delicious!

Georgie
Do these brownies have to be stored in the fridge since they contain fresh zucchini?
Kate
They should be ok for a few days, in an airtight container.
Messy me
Strange question:
Would this work with grated melon?
I have a cantaloupe which is kind of hard and really not sweet – all peeled and cut, for nothing. Too meh for eating.
Melons are related to zucchini, via pumpkins, right?
….
Kate
I’m not sure, but I’m hesitant that it would as melons have more water to them.
shaye
I cannot find spelt flour or whole wheat pastry flour near me can I sub in just whole wheat flour?
Kate
I don’t think you will get the same result, sorry!
Laura
You need to bump this recipe on the blog! My daughter and I made them today and they are so delicious. We didn’t have enough coconut oil so I subbed in some unsweetened apple sauce and they were awesome.
Nithya
Have you used Oats flour for this recipe? Would be able to give me oat flour measurements please?
★★★★★
Kate
Hi! I haven’t used it with this. I’m not sure it would work well with the zucchini, but you could try it! Follow my oat flour notes in my post about using oat flour.
Melanie
I make these as mini muffins for my children’s lunches. I baked them for 15 minutes and they are delicious! My little ones LOVE them! Your recipes are fantastic!!
★★★★★
Karine
Ok. These brownies are just divine. There is no other word! I followed the recipe almost exactly (I added a bit less chocolate chips because half of mine were mini, which takes less to make the same amount), and the result is spectacular. I was afraid they would taste too much like coconut (because of the coconut oil), but they don’t!
Perfect brownie recipe. Thank you!!

Lori
Kate,
Just finished eating the vegetable lasagna. It was very good! I will be adding that to my rotation of meals. I have made a lot of your recipes. I have enjoyed every single one of them. The doctor suggested that I go on a vegetarian eating style due to high cholesterol. I have to make a few tweaks to some of your things because I can’t eat eggs. So I just use all whites in my cooking. Thanks for helping me to transition into this type of eating. I feel good and my ldl has gone down 26 points in 6 weeks. I go for another blood test at the end of the month. My doctor was the one who recommended your site.
Thank you
★★★★
Eva
So good! Didn’t have whole wheat pastry flour or spelt, so I used 1 cup regular whole wheat and 3/4 of a cup AP. Came out great . Not the fudgiest ever but not cakey either, perfect middle ground. Perfect flavour. I’m in love! :) I think the cinnamon is the cherry on top flavor vise. In my opinion cinnamon compliments pretty much any sweet flavor. Like next time you’re having chocolate ice cream – dust some cinnamon on it! So good!
★★★★★
Kate
Thank you for sharing, Eva! I’m happy you were able to enjoy it.

Quick hack for drying grated zucchini is to use a salad spinner – works for potatoes too!
