In 8th grade, my middle school’s concert bands planned a four-day field trip to Disneyland. Our band director scheduled a performance for us inside of the theme park, but for the remainder of our two days in Anaheim, we raced around Disneyland to fit in all of our favorite rides.
For the eight-hour bus rides from our Northern California town and back, the chaperones packed plenty of VHS tapes to keep us occupied. Of course, knowing our destination… Most of those movies were Disney-themed, like “Aladdin,” “The Little Mermaid,” and “The Lion King!”
During the last half hour of our Sunday drive, one chaperone popped in “The Lion King 1 ½.” Since my friends and I hadn’t seen it, we were bummed to miss the ending when the bus pulled into the middle school parking lot, so we decided to meet up at my house the next weekend to watch the rest.
That afternoon, my mom picked up pizzas from our favorite restaurant, and I whipped up a batch of boxed mix brownies (each of my friends had a sweet tooth as big as mine!). Before settling into the family room and pressing play, we grabbed paper plates to serve ourselves lunch.
Because I forgot to cut the pan of brownies, the first guy to reach them offered to help out. Mom handed him a knife, but… In his excitement over dessert, he sliced the most lopsided diagonal lines I’ve ever seen. Each brownie looked more like an uneven trapezoid or rhombus — not a single one was rectangular!
Since then, every time I cut a batch of brownies, I think about that funky geometric pan… And feel very tempted to pull out a ruler, especially if I’m planning on photographing them to share with you!
And yes, that happened with these Healthy One-Bowl Chocolate Chunk Brownies too! I think I did a decent enough job cutting them… Hopefully?? But regardless of how they look, they taste absolutely amazing! Rich, fudgy, decadent, chocolaty… Basically like squares of fudge with even more bits of chocolate sprinkled throughout.
Healthy, pretty, and positively delicious — that makes my chocoholic heart so happy! ♡
KEY INGREDIENTS TO MAKE HEALTHY CHOCOLATE CHUNK BROWNIES
Before slicing them into perfect squares — with or without a ruler! — you’ll have to make the batter first… So let’s talk about the key ingredients that you’ll need to bake a batch of these healthy chocolate chunk brownies!
Unsweetened cocoa powder. This just might be the most important ingredient in the entire recipe! Unlike many traditional “from scratch” brownie recipes, you aren’t using any melted chocolate (aka they’re faster to whip up and result in fewer dishes to wash — hooray!), so cocoa powder provides all of that rich chocolate flavor in the batter.
You’ll need regular unsweetened cocoa powder to make these chocolate chunk brownies. Because you’re adding equal amounts of cocoa powder and flour (more on that momentarily!), your brownies end up tasting incredibly rich and decadent, even without any melted chocolate in the batter.
Tip: Do not substitute Dutched or special dark cocoa powder. These have a milder and more muted flavor, which makes these brownies taste bland. They also have a different acidity level, which can change the texture of your brownies.
Flour. To make these chocolate chunk brownies healthier, I opted for white whole wheat flour. No, as confusing as it may sound, it isn’t just a combination of white (aka all-purpose) flour and whole wheat flour!
Here in the US, 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 richness and fudginess of these brownies truly shine!
Tip: If you’d like to make your healthy chocolate chunk brownies gluten-free, then see the Notes section of the recipe. I’ve included how to do so there!
Coconut oil or butter. Also unlike many traditional recipes that call for ½ cup of oil or butter, you need a mere 1 tablespoon to make these. That really helps keep your healthy chocolate chunk brownies low calorie and low fat! Yet they’re just unbelievably moist and fudgy, just like “regular” brownies, because of…
Greek yogurt. It’s one of my favorite healthy baking ingredients for a reason! In this brownie recipe, Greek yogurt adds the same moisture to the batter as extra oil or butter — but for a fraction of the calories. It also gives your chocolate chunk brownies a protein boost!
Egg whites. A common baking ingredient! Egg whites act like the glue that holds the rest of the ingredients together. (Similar to Greek yogurt, they also give your chocolate chunk brownies a protein boost!)
Sweetener. Instead of granulated sugar, you’ll sweeten these healthy chocolate chunk brownies with coconut sugar. Coconut sugar is exactly what it sounds like: an unrefined sweetener that comes from coconuts. However, it does NOT actually taste like coconuts! It’s sweet with nice caramel-like undertones, very similar to brown sugar, which adds to the rich and comforting flavor of these brownies.
Milk. Almost any type will work, so you’re welcome to mix in whatever kind you already have stashed in your fridge. I typically bake these healthy chocolate chunk brownies with nonfat milk or unsweetened vanilla almond milk, and both perform equally well.
Dark chocolate. After the cocoa powder, this is the second most important ingredient… It’s impossible to make chocolate chunk brownies without the chocolate chunks!
For the best results, grab a bar of dark chocolate and chop it into chunks yourself. I reach for Ghirardelli and Lindt the most! I aim to cut them about the same size as miniature chocolate chips. This ensures every bite of brownie has a chunk of chocolate!
Hint: Bars of dark chocolate will actually melt in the oven, as opposed to chocolate chips, which often contain a stabilizer that prevents them from fully melting. If you like perfectly melty chocolate and extra fudgy brownies (I certainly do!), then it’s 100% worth the time to chop a bar yourself!
HOW TO MAKE HEALTHY ONE-BOWL CHOCOLATE CHUNK BROWNIES
Now that you’ve gathered the ingredients, let’s quickly go over how to make the best healthy chocolate chunk brownies. Like I promised earlier, this recipe is easy to make — and I also have some tips to ensure your batch turns out perfectly!
Measure correctly. You may have heard this once or twice… But it’s absolutely essential, so I’m going to repeat it again.
It’s extremely important to measure the flour and cocoa powder correctly. Use this method or a kitchen scale. (← That’s the one I own!) Do NOT scoop either one directly from its container! That can result in adding 1 ½ times as much as called for in the recipe.
Too much of either of these ingredients will throw off the ratio of wet and dry ingredients, and it’ll make your brownies cakey and dry, rather than moist and fudgy. Too much cocoa powder will also make your brownies taste bitter, instead of rich and chocolaty.
So for the best flavor and texture, take the time to measure properly. I promise these chocolate chunk brownies are worth it!
Follow the instructions exactly. Just like we were taught back in math class… Order of operations matters — especially in a one-bowl recipe!
For a few examples, certain ingredients need to be mixed together and fully dissolved before you add others to the bowl. The baking powder needs to wait until almost the very end (to avoid activating it too soon) and be sprinkled (to avoid clumps and ensure the best fudgy texture). The chopped chocolate goes last for even distribution and to help prevent it from sinking to the bottom of the bowl.
Therefore… Add when you’re supposed to add, sprinkle when you’re supposed to sprinkle, and stir when you’re supposed to stir. And that leads us to…
Mix by hand. Put away your stand mixer and hand-held mixer! Those tend to overmix low fat batters, like this one. Overmixing often leads to a tough, gummy, or rubbery texture — rather than the moist and fudgy brownie consistency that we want.
To make the best chocolate chunk brownies imaginable, whisk when explicitly instructed, and use a fork for everything else. Yup, a fork! It’s my not-so-secret trick. You can see it in my photo above! The open spaces between the tines let the ingredients pass through and mix more efficiently (compared to the flat sides of spoons and spatulas), which also helps guard against overmixing.
Bake. You’ll bake these brownies at a lower temperature, only 300°F, to ensure they’re supremely fudgy without the edges drying out. The brownies will be ready to come out of the oven when the edges look fully baked through but the center still looks glossy and underdone. The residual heat from the pan will cook the center all the way through while your brownies cool on the counter.
Hint: If the brownie edges pull away from the rim of the pan within 10 minutes of pulling them out of the oven, you baked them long enough!
Cool + rest. Yup, both. Cool and rest. I know it feels almost impossible to wait for your brownies to rest for at least 8 hours after they’ve reached room temperature… But I promise that results in the fudgiest texture! If you cut into them sooner, they’ll have a more cakey texture instead. Leaving the pan untouched and alone allows the brownies time to work their magic and yields an amazingly moist and fudgy consistency. (I’m definitely “Team Fudgy” when it comes to brownies!)
Tip: Once your brownies have reached room temperature, you can pop the pan in the fridge for a couple of hours to speed up the resting and setting process!
That stack… Pure chocolate heaven! 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 one-bowl chocolate chunk brownies!
Healthy One-Bowl Chocolate Chunk Brownies
Ingredients
- 1 tbsp (14g) unsalted butter or coconut oil, melted and cooled slightly
- 2 large egg whites, room temperature
- 1 tsp vanilla extract
- ¼ tsp salt
- ¼ cup (60g) plain nonfat Greek yogurt
- ½ cup (96g) coconut sugar
- 6 tbsp (90mL) nonfat milk
- ¾ cup (60g) unsweetened cocoa powder (measured like this)
- ¾ cup (90g) white whole wheat flour or gluten-free* flour (measured like this)
- ¼ tsp baking powder
- 3 tbsp (42g) finely chopped dark chocolate (see Notes!)
Instructions
- Preheat the oven to 300°F, and coat an 8”-square baking pan with nonstick cooking spray.
- In a medium bowl, whisk together the butter or coconut oil, egg whites, vanilla, and salt. Stir in the Greek yogurt, mixing until no large lumps remain. Stir in the coconut sugar. Stir in the milk. Add in the cocoa powder, stirring just until incorporated. Add in the flour, then evenly sprinkle the baking powder across the top of the flour (to prevent clumping). Gently stir until just incorporated. Gently fold in 2 ½ tablespoons of the chopped dark chocolate.
- Spread the batter into the prepared pan, and gently press the remaining chopped dark chocolate into the top. 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 8 hours at room temperature for the fudgiest texture before serving.

I really enjoyed this recipe! Considering how healthy it is, it really satisfied my chocolate cravings! I will say it had a bit of a healthy taste which was probably mostly because of the whole wheat flour but I was still super satisfied with them. Not a very typical brownie texture as mine were very thin and had the texture of fudge than that of a brownie. I’ll definitely come back to this recipe next time I want a healthy brownie!
I’m so glad you enjoyed these brownies, Julia! 🙂
I’d love to help you solve the mystery about why your brownies were so thin and that “healthy” taste, if you’d like. In order to do so, I have a few questions for you!
Did you make any modifications or substitutions, including those listed in the Notes section?
What brand of whole wheat flour did you use?
Did you use a kitchen scale or measuring cups/spoons for all of the ingredients (especially the flour, cocoa powder, and milk)?
How long did you bake your brownies?
How long did you let them (a) cool and (b) rest before slicing into them?
When you measure your square baking pan, is it 8″ across the bottom of the pan or across the top rim?
I know I just asked a LOT of questions, but I’ll have a much better idea of what you can do to make your brownies even better the next time you make a batch! 🙂
Hi my batter came out a bit thin? Is that supposed to happen.
It means a lot that you tried my recipe! It shouldn’t be as thin as pancake or cake batter, but it shouldn’t be as thick as cookie dough either. Can you describe the consistency of your brownie batter a bit more?
If you watch my video that I linked to in the bottom of the recipe’s Notes section (at the very bottom of the recipe box — I know it can be easy to miss!), was your batter thinner than mine?
Also, did you make any substitutions or modifications to the recipe, including those listed in the Notes section?
I’m happy to help figure out what’s going on — I could just use a little more info to do so! 🙂
I used the same measurements and ingrediants. It was a soupy consistancy. I did no mods but I subbed the flour for oat flour.
Thanks for sharing! That’s really strange it was a soup-like consistency. That shouldn’t happen! Did you use the full amount of oat flour, cocoa powder, and coconut sugar? Also, did you use a kitchen scale or measuring cups/spoons for all of the ingredients?
I used measuring cups and used the full amount of oat flour cocoa powder and coconut sugar. They also have a very ‘healthy’ like tatse
Thanks for this additional information! Something still isn’t adding up correctly. If the exact measurements of all ingredients were used, and oat flour was the only modification that was made, then the brownie batter should have a pretty thick consistency. It would almost hold its shape if scooped up with a spoon, and it would gradually ooze off the sides of the spoon.
Since yours was much thinner in consistency than that, it sounds like there was either {a} too much liquid (butter/coconut oil, egg whites, Greek yogurt, milk), {b} too much coconut sugar (sugar counts towards the liquid ingredients in batters like this because it dissolves in milk, which therefore “bulks” up the liquid!) or {c} not enough dry ingredients (cocoa powder and flour).
Did you use whole eggs or egg whites from a carton, by any chance?
What brand of Greek yogurt did you use?
Did you use cups or tablespoons to measure the milk?
What was the texture like after the brownies rested at room temperature for 6+ hours?
Can you describe what you mean by a “healthy” flavor a bit more? Too bitter, too bland, not chocolaty enough, oat-like, something else?
I’m happy to continue trying to solve this brownie mystery, and your answers to all of the above questions will help me do that! 🙂
I really appreciate your interest! I just came back to this recipe because I’m planning on making them again tomorrow. Looking at your questions, I realized that I used regular whole wheat flour instead of white whole wheat flour like you suggested. I tend to find that whole wheat flour gives a kind of healthy taste in most recipes so I think I’ll use all-purpose flour this time. Thanks for your help!
It’s my pleasure, Julia! If you’re willing to share the answers to my other questions, I’m happy to help solve the other issues you experienced, especially the thinness. White whole wheat flour, regular whole wheat flour, and all-purpose flour won’t affect the thinness (only the flavor!), so it sounds like there’s something else going on too. I’ve shared the same questions I asked you before here, just in case that’s easier for you! 🙂
Did you make any modifications or substitutions, including those listed in the Notes section?
Did you use a kitchen scale or measuring cups/spoons for all of the ingredients (especially the flour, cocoa powder, and milk)?

When you measure your square baking pan, is it 8″ across the bottom of the pan or across the top rim?
Could almond flour be used in place of white whole wheat flour?
I really appreciate your interest in my recipe, Melissa! In this particular recipe, almond flour should work as a substitute. Because it’s less absorbent than wheat-based flour, there’s a chance that you may need to add an extra tablespoon or two to achieve the same batter consistency and brownie texture. The flavor should remain the same though! 🙂 I’d love to hear what you think of these brownies if you end up making them!
