Last summer, I finally found the courage to try the combination of chocolate and zucchini. I already knew I loved zucchini paired with chocolate chips, like in my favorite zucchini bread and zucchini mini muffins, but somehow, the thought of a pure chocolate treat with zucchini inside sounded incredibly weird.
Still, I kept seeing that combination all over my Instagram and Pinterest feeds, so I bravely walked into my kitchen and pulled out the ingredients to bake my favorite chocolate muffins… With a vegetable hidden inside. Hmm.
I carefully measured the flour and cocoa powder, and I sprinkled in cinnamon at the last second because that’s what I always do with my plain zucchini treats… So despite all the weirdness, somehow that cinnamon addition felt right.
After folding the grated zucchini into the batter and realizing there was no going back, I divided the green-flecked chocolate batter between my muffin cups and popped them in the oven. When the timer buzzed and I pulled out the muffin pans, they smelled rich and decadent like usual… With a hint of added warmth and coziness from the cinnamon.
That actually smells really good… I thought, which gave me the last bit of courage I needed to try a bite once the muffins cooled for a few minutes. As I cautiously brought the first muffin to my mouth for a taste… And swallowed the first mouse-sized bite…
I looked down at the muffin in my hand in absolute amazement. “That tastes amazing!” I actually blurted out loud. “Why did I wait so long to try this??”
In that instant, I immediately became obsessed with the chocolate + zucchini flavor combination… So I’m incredibly excited to share this Healthy Fudgy Dark Chocolate Zucchini Brownies recipe with you!
They’re supremely rich and fudgy, exactly the way I love my brownies, with lots of zucchini and that irresistible hint of cozy cinnamon. Yet unlike other zucchini brownie recipes I’ve seen, these contain no refined flour or sugar—and only 63 calories!
Let’s talk about how to make these healthy zucchini brownies!
You’ll begin with a combination of white whole wheat flour (like this!) and cocoa powder (like this!). White whole wheat flour actually exists… And it’s not a combination of white (aka all-purpose) flour and whole wheat flour!
Instead, white whole wheat flour is made by finely grinding a special type of soft white wheat (hence the name!), whereas regular whole wheat flour comes from a heartier variety of red wheat. This gives white whole wheat flour a lighter taste and texture, closer to that of all-purpose flour, which lets the chocolate flavor and fudgy texture truly shine in these healthy zucchini brownies!
As for the cocoa powder, you just need regular ol’ unsweetened (like this!). Because we’re adding equal amounts of flour and cocoa powder, your brownies will already taste really rich and chocolaty without Dutched or special dark cocoa powder.
However, it’s extremely important that you measure the flour and cocoa powder correctly, using this method or a kitchen scale. (← That’s the one I own!) Too much of either will make your brownies turn out dry and crumbly, and too much cocoa powder will make them taste bitter, rather than rich and chocolaty.
Unlike traditional brownie recipes that call for ½ to 1 full cup of oil or butter, these healthy zucchini brownies only require 1 tablespoon. Yes, that’s it! The rest of their fudgy texture comes from Greek yogurt. If you’ve been around my blog, you know how much I love it! Greek yogurt adds the same moisture to your brownie batter as extra butter or oil for a fraction of the calories, and it also gives your treats a protein boost.
Such a great trick for making low-calorie zucchini brownies, right??
To sweeten your brownies, you’ll skip the refined granulated sugar and use coconut sugar (like this!) instead. Coconut sugar is exactly what it sounds like: an unrefined sweetener that comes from coconuts. However, it does not actually taste like coconuts! It has a rich caramel-like flavor, similar to brown sugar, which makes these brownies taste even better.
Of course, we can’t forget the key ingredient in these healthy brownies… The zucchini! You’ll use freshly grated zucchini that you’ve patted dry with paper towels. It’s important to remove that extra moisture because otherwise, the zucchini will release that water into the batter while your brownies bake, so they’ll take much longer to finish baking and will turn out more cakey than fudgy. I promise it’s worth the tiny bit of extra effort!
One last thing! You must let your brownies rest for 8 hours once they’ve cooled to room temperature. Yes, it’s hard. Yes, it’s painful. Yes, it’s so tempting to slice into them and try one earlier. Yet the brownies turn fudgier the longer they sit (and the zucchini softens more, too!), so instead of warm cakey fresh-from-the-oven brownies, you end up with extremely fudgy brownies with the most irresistible texture imaginable.
Seriously, how amazing do these look?? And when you make your own, remember to snap a picture and share it on Instagram using #amyshealthybaking and tagging @amyshealthybaking IN the photo itself! (That guarantees I’ll see your picture! 😊) I’d love to see your healthy zucchini brownies!

- ¾ cup (90g) white whole wheat flour or gluten-free* flour (measured like this)
- ¾ cup (60g) unsweetened cocoa powder (measured like this)
- ½ tsp ground cinnamon
- ¼ tsp baking powder
- ¼ tsp salt
- 1 tbsp (14g) unsalted butter or coconut oil, melted and cooled slightly
- 2 large egg whites, room temperature
- 1 tsp vanilla extract
- ¼ cup (60g) plain nonfat Greek yogurt
- ½ cup (96g) coconut sugar
- 6 tbsp (90mL) nonfat milk
- 1 cup (90g) freshly grated zucchini (see Notes!)
- Preheat the oven to 300°F, and lightly coat an 8”-square baking pan with nonstick cooking spray.
- In a medium bowl, whisk together the flour, cocoa powder, cinnamon, baking powder, and salt. In a separate bowl, whisk together the butter, egg whites, and vanilla. Stir in the Greek yogurt, mixing until no large lumps remain. Stir in the coconut sugar. Stir in the milk. Add in the flour mixture, stirring until just incorporated. Gently fold in the grated zucchini.
- Spread the batter into the prepared pan. Bake at 300°F for 15-19 minutes (15 minutes yields the fudgiest brownies; 19 minutes yields slightly cakier brownies). Cool completely to room temperature in the pan, and let the brownies sit for at least 6 hours at room temperature for the fudgiest texture before serving.
Regular whole wheat flour, whole wheat pastry flour, or all-purpose flour may be substituted for the white whole wheat flour. Oat flour (gluten-free, if necessary!) may be substituted as well, but be extremely careful when measuring it!
I don’t recommend using Dutched or special dark cocoa powder. The brownies already taste very rich and dark chocolaty without it! Make sure you measure the cocoa powder correctly, using this method or a kitchen scale. (← That’s the one I own and love!) Too much will dry out your brownies and make them taste bitter.
If your cocoa powder is very bumpy and/or clumpy, then sift it into the mixing bowl.
Brown sugar or granulated sugar may be substituted for the coconut sugar, but the brownies will no longer be clean eating friendly.
Any milk may be substituted for the nonfat milk.
If you’d prefer, ½ cup (120mL) of pure maple syrup, honey, or agave may be substituted for the coconut sugar and 4 tablespoons of the milk. (You still need to add those 2 final tablespoons of milk!)
Measure the zucchini before patting it dry. You must pat it dry to remove the excess moisture because that excess moisture will cause the brownies to have too much liquid and turn out more on the cakey side, rather than fudgy. To pat the zucchini dry, lay a double-thick layer of paper towels onto a cutting board, and arrange the freshly shredded zucchini on top. Place another double-thick layer of paper towels on the zucchini, and firmly press down until the top towel turns completely wet.
You must wait 8+ hours before slicing and serving! If you cut into them while warm, they’ll taste cakey instead of crunchy, and the zucchini will be on the “al dente” side. The brownies turn fudgier the longer they rest on the counter, and the zucchini softens more as well. I promise it’s worth the wait!

Hello, the last step says to “gently press the remaining chopped dark chocolate into the top.” But there is no chopped dark chocolate in the ingredients. Is this an error?
I’m wondering the same thing….chopped dark chocolate?
Is part of the creation story missing…?
Thanks!
Thanks for catching that typo, Cheryl and Kimberly! All fixed! 🙂 I’d love to hear what you think if you try these brownies!
This looks delicious and I want to say I low your website and and your recipes. However, I am a little older and having vision problems, and your font is so small and so very light I have difficulty reading it, and is especially frustrating when I am preparing. Is there any way you could make your font a little darker or larger? I hope this doesn’t sound petty or weird , I understand if you don’t want to , most of your audience is probably younger. Blessings Sharin
I truly appreciate your kind words and interest in my recipes, Sharin! I’ll keep your advice in mind when I next speak with my website designer. 🙂 I’d love to hear what you think if you try these brownies!
Gotta try these!! They look so yummy!
You’re too sweet — thanks Karly!! 🙂 I’d love to hear what you think of these brownies if you do!
Sometimes I want to up the protein to make your delicious snacks into something I can eat after a good workout – can I substitute some of the flour for protein powder? How much would you recommend? Thank you! I <3 your recipes!!
You’re so sweet — thank you Jessica!! It means the world to me that you’re enjoying my recipes! 🙂 Unfortunately, all protein powders behave differently in baking recipes, so I can’t guarantee how that substitution will work out. I have an entire FAQ Page dedicated to protein powders here — perhaps that’ll be useful to you! You can also find all of my really high protein recipes here and my higher protein recipes here. I’d love to hear what you think if you try these brownies!
Oh thank you! I didn’t know I could search through your recipes like that. I’m going to try your zucchini bread protein muffins…and maybe add a dollop of PB on top! Thank you so much – I appreciate your reply!!
It’s my pleasure, Jessica! I’m always happy to help! 🙂 I can’t wait to hear what you think of the zucchini bread protein muffins — and I LOVE your idea of PB on top!
Hello dear,
Can I subsitute the eggs for something else or are they necessary ?
Thank you so much these recipes !
I really appreciate your interest in my recipes, Cynthia! My brother is actually allergic to eggs, and Ener-G is my favorite substitute. Ener-G is a shelf-stable powder that keeps for ages. It works perfectly as an egg replacer in nearly all of my recipes, including this one! For my recipes, use 1 ½ teaspoons Ener-G + 2 tablespoons warm water for each egg white, and you’ll need an additional ½ tablespoon of butter or coconut oil {or Earth Balance, if you’re vegan!} for each egg yolk. 🙂 I can’t wait to hear what you think of these brownies!
They sound delicious! Where can you buy white whole wheat flour and can you freeze the dough ahead of time before you bake them?
Thank you so much!
I really appreciate your interest in my recipe Annette! I can find white whole wheat flour at most grocery stores, as well as some Walmart and Target stores, here in the US. If you’re in the UK or Australia, it’s the same thing as your regular wholemeal flour. If you’d like to freeze these brownies, it’s better to do so once they’ve been baked, have full set and cooled, and have been sliced into squares. 🙂 I can’t wait to hear what you think of them!
Thank you so much for your recipes!
Can you freeze the dough before you bake it?
There is no cinnamon in ingredients
Now there is! Thanks for catching that Diana! 🙂 I’d love to hear what you think of these brownies if you try them!
