Healthy Brownies

Brownies are hands down one of my favorite desserts — the richer and fudgier, the better! And if I don’t have a plan for a batch of brownies to go (family, friends, neighbors, etc.) they will all get consumed by yours truly. Literally, every single piece, and I wish I were exaggerating but I’m not.

As a result, I’ve worked and worked and worked on a healthy recipe that I absolutely love but has better ingredients, because I shouldn’t eat this entire tray of Peanut Butter Cup Brownies. So now, when I eat these at least I’m getting some health benefits from it. ๐Ÿ™‚ 

What to expect from this recipe

This brownie recipe is one of the recipes I am proudest of — it’s pretty amazing how great the ingredients are for the insanely fudge-y, rich, and delicious flavor and texture these brownies deliver. But I also want to be completely transparent; these brownies aren’t for everyone. Read on to see what I mean.

Texture-wise: So, this is probably contrary to every single brownie law of the universe, but these healthy brownies are best served cold. Cover these tightly and chill them overnight (or about 4-6 hours) and then you’ll know what I’m talking about. They taste like rich, dark chocolate fudge. After being chilled they are very dense and not at all cake-like. When warmed up they do have a lighter and more cakey texture. Healthy Brownies are thick, chewy, and quite rich (especially with the frosting on them).

Flavor-wise: These brownies have a slightly bitter, strong dark chocolate flavor. I use 53% cacao dark chocolate so I don’t find them overly bitter, but they do taste strongly of dark chocolate. If you don’t love dark chocolate, you can use milk chocolate. Beyond the dark chocolate, these also have a lot of Greek yogurt in them. I recommend you use a good, sweet, and non-tangy Greek yogurt (more on this later).

Healthy Brownie Ingredients

Here are the ingredients I use and recommend for the best results in this recipe. None of them are sponsors; they’re just what I use when making this recipe.

  • Dark chocolate. I use Nestle’s® Dark Chocolate Chips. Read up on the benefits of dark chocolate here. If you’re not a dark chocolate fan, milk or semi-sweet will work in its place.
  • Greek yogurt. This is in my opinion the most important ingredient in this recipe. It can definitely make or break the final flavor. I have tried so many different Greek yogurts and hands-down, the best yogurt to use is Honey Vanilla Greek yogurt (made by Greek Gods®). Greek yogurt contributes loads of protein to these brownies, among other benefits.
  • Coconut oil. I have found a good amount of variation in coconut oil brands; mainly there is a stronger coconut flavor in some brands as opposed to others. I personally use LouAna® Coconut Oil and don’t find any recognizable or pronounced coconut flavor in these Healthy Brownies.
  • Vanilla extract, salt, and baking soda. These ingredients contribute to the flavor and leavening of the brownies.
  • Coconut sugar. This sugar is a non-refined sugar that has become very mainstream in grocery stores in the last few years. You should be able to find it among other baking sugars or in the health food section of your grocery store. If you don’t want to buy a special sugar for this recipe, brown sugar can be used instead. It’s a 1:1 substitute, but note that brown sugar is refined sugar.
  • Old-fashioned oats. More on this ingredient in the next paragraph.

Let’s talk oats

If there’s no flour in these flourless healthy brownies, what are we using? Regular old-fashioned oats! (Make sure to use old-fashioned or rolled oats, not quick or steel-cut oats). The oats are blended up before being added to the batter, and they resemble flour and serve the same function; read the “quick tip” below for a breakdown of the process.

Quick Tip

How to make powdered oats: Add the old-fashioned oats to a food processor or small blender jar. Pulse the oats until they are ground into a powder-like consistency that resembles flour. Stir the oats around to be sure that all the oats have been finely ground and there aren’t any whole oats left. (This will affect the texture and liquid absorption of these flourless brownies.) Make sure to measure the oats once they’ve been blended into a powder and not before.

Healthy Brownies Frosting

The frosting on these is optional. While it is a whole lot healthier than most frosting recipes, it does have refined powdered sugar in it. If you are avoiding refined sugar, you’ll want to leave off the frosting on this recipe.

The frosting contains only four ingredients and uses similar ingredients in the brownie base — more dark chocolate and more Greek yogurt, plus some milk and powdered sugar. I use almond or macadamia nut milk, but any plant-based milk works great here.

The frosting is very thick and ganache-like. It will harden as it sets and firms up on the cold brownies. It can soften and get melty in a warm environment, so I recommend keeping these brownies chilled.

Tips

  • Use the right ingredients. Take a minute to read through the ingredients section. The ingredients matter a lot on this recipe and you can end up with very delicious or, er… less-than-exciting, brownies, based on the ingredients used.
  • Line the pan. These brownies are very fudge-y and can be difficult to get out of an unlined pan. Save yourself the trouble by lining the pan with parchment paper and leaving an overhang for easy removal.
  • Wait until they’re chilled. These brownies are at their best after being chilled overnight. We love them best the next day. But even a few hours in the fridge and they’re delicious.
  • Use a sharp chef’s knife to make cuts. Run the knife under warm water, dry on a kitchen towel, and repeat for each cut. These brownies are rich and sweet that you’ll want to cut them pretty small.

Healthy Brownies

The best Healthy Brownies! Made without flour, refined sugar, butter, or eggs, these rich, fudgy, and deeply chocolatey brownies can be easily prepared with ingredients found at your local grocery store. Plus, there's an optional frosting recipe for those who love frosted brownies.
Prep Time: 30 minutes
Cook Time: 30 minutes
Chilling Time: 6 hours
Total Time: 7 hours
Servings: 16 bars

Ingredients 
 

Brownies:

  • 1 and 1/2 cups (53% cacao) dark chocolate chips divided Note 1
  • 1/4 cup + 2 tablespoons coconut oil Note 2
  • 1 cup honey vanilla Greek yogurt Note 3
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon fine sea salt
  • 1/2 teaspoon baking soda
  • 1/2 cup coconut sugar (or use light brown sugar)
  • 3/4 cup oat flour (just blend regular oats in your blender)

Optional Frosting:

  • 1/2 cup dark chocolate chips
  • 2 tablespoons unsweetened vanilla almond milk or whatever milk you have on hand
  • 2 tablespoons vanilla Greek yogurt
  • 3/4 cup powdered sugar

Instructions 

  • PREP: Preheat the oven to 350 degrees F (176 degrees C). Line an 8x8-inch pan with parchment paper, leaving an overhang for easy removal. Lightly spritz with nonstick cooking spray.
  • MELT CHOCOLATE: In a large bowl place 1 cup (175g) of chocolate chips and set aside. Add the solid coconut oil to a separate, microwave-safe bowl. Microwave the coconut oil and then measure the coconut oil in its melted, hot state to get 1/4 cup + 2 tablespoons. Pour the hot melted coconut oil over the dark chocolate and stir the chocolate until it is completely melted. If needed, microwave the chocolate and coconut oil in 10-15 second bursts, stirring in between each burst for 20 seconds until completely melted and smooth. Let cool slightly.
  • REMAINING INGREDIENTS: Add in the Greek yogurt; stir to combine. Stir in the vanilla, salt, baking soda, and coconut sugar (or brown sugar).
  • BLEND OATS: Add old-fashioned oats to a blender or food processor. Blend or process until the oats are fine and resemble flour. Measure the oat flour after blending and not before, to get a level 3/4 cup. Add blended oats and remaining 1/2 cup (91g) chocolate chips to brownie batter. Mix to combine.
  • BAKE: Spread the mixture (it is very thick) into the prepared pan in an even layer. Bake in the preheated oven for 28-32 minutes or until a fork comes out clean when inserted into the center. Do not overbake. Slightly underbaking is better and will yield a superior taste and texture (more fudge-like). Remove from the oven and allow the pan of brownies to cool completely at room temperature on a wire cooling rack. If desired, frost the cooled brownies (see next step).
  • OPTIONAL FROSTING: In a microwave-safe bowl, combine the 1/2 cup chocolate chips and 2 tablespoons milk. Microwave in bursts of 15 seconds, stirring for 15 seconds in between each burst until the chocolate is completely melted. Stir in the Greek yogurt until fully incorporated and then whisk in the powdered sugar. Frosting may seem thin -- don't worry; it thickens as it cools. Let stand at room temperature for 10 minutes and then spread frosting evenly over the brownies.
  • CHILL: Cover the frosted (or unfrosted) brownies and place them in the fridge to fully chill. These brownies are best cold (we like them best after being chilled 6-8 hours). Once chilled through, remove the brownies using the overhang of the parchment paper. Cut into small pieces and enjoy!
  • STORAGE: Store leftover brownies in an airtight container in the fridge for 3-5 days. Freeze individually wrapped brownies for up to 2 months. The frosting does get a bit watery upon being thawed.

Recipe Notes

Note 1: We like Nestle's Dark Chocolate Chips best in these brownies. Too high of a cacao content in dark chocolate chips and the brownies will taste bitter. The chocolate chips are essential to the recipe, so don't leave them out or interchange them with cocoa powder.
Note 2:ย  Greek yogurt is arguably the most important ingredient in this recipe. It can definitely make or break the final flavor. I have tried so many different Greek yogurts and hands down the best yogurt to use is Honey Vanilla Greek yogurt (made by Greek Godsยฎ). If you do not love the Greek yogurt straight out of the container, you will likely not love this recipe -- the Greek yogurt is a huge component. I also recommend adding a flavored Greek yogurt (honey or vanilla flavored) instead of plain.ย 
Note 3: I have found a good amount of variation in coconut oil brands; some brands leave a stronger coconut flavor in some brands than others. I personally use LouAna Coconut Oil and don't find any recognizable or pronounced coconut flavor in these brownies.

    Made these little monsters for work and they were 100% success! (I haven’t tried them yet but everyone in my office has so rumor hast it^^)
    The texture is intense especially using the greek yogurt and it all depends on the chocolate you use (75%).
    I made alterations though and instead of using coconut sugar I opted for dessicated coconut (40g, 10g stavia and 10g brown sugar). I also only used 3/4 cups of icing sugar – you really dont need more than that, probably even less. Also opted out of chocolate chips as they are usually worse in cocoa content.
    Will make this again next week for sure x

    1. chelseamessyapron says:

      Yay!! So thrilled to hear these were a huge success! I’m so happy they were enjoyed throughout the office ๐Ÿ™‚ Thanks for the comment Natalie!

    I made these last night with whole wheat flour and they turned out delicious but more crumbly and very very soft like a sponge cake almost. I was really hoping they’d be nice and chewy ? Did I do something wrong?

    1. chelseamessyapron says:

      Yes, they shouldn’t be crumbly or soft. I believe that is because you used the whole wheat flour. The oat flour works very differently in these than whole wheat flour. Also if you chill them they really get quite dense and fudgy like a brownie. Hope you give these another try with the oats instead of the flour!

  3. Cathy says:

    I am prepping to start The Zone Diet, and I was wondering if you have the nutritional values for the brownies. I need the protein, carbs and fats to figure it out. I’d love to try these…..even just to have when I’m craving chocolate.

  4. Gabby says:

    Made these brownies but the taste wasn’t what I hoped for. It was a bit salty, and I’m not sure what I did wrong because I followed the recipe exactly. I will try making them again.

    1. chelseamessyapron says:

      Oh I’m sorry to hear these aren’t what you were looking for. Did you try them chilled? I’ve never thought them to have any salty taste so is it possible you mis-measured the salt? If not, maybe just omit the salt next time ๐Ÿ™‚

  5. patricia johnson says:

    Hello your brownies look delicious I would like to know are any diabetic friendly?

  6. Alyssa says:

    Any other healthy substitutes for the oat flour? Like how is wheat flour?

    1. chelseamessyapron says:

      I’m not sure; I haven’t tried wheat flour in these. If you do try it be aware that the oat flour absorbs a lot more liquid than wheat flour so the measurements wouldn’t be an exact substitution.

    Hi! I’m making a “clean” white cake with chocolate frosting for a Fitness instructor friends’ birthday. It will be a 2-layer 8″ cake.I plan on using the frosting from your brownies, because it was love at first bite! Will this be an easy recipe to double, even maybe triple?? And do you think it is too heavy for a plain white layer cake. Aaaand, can I whip it to make it lighter and more spreadable or do I need to add more liquid? Sorry for all the ??? but I really want this to work!!!! Thanks!!!

    1. chelseamessyapron says:

      How nice of you!! And I’m so happy you enjoyed the frosting ๐Ÿ™‚ I think it would be fine to double, but triple might get a little tricky just with melting the chocolate evenly. I also don’t think it would be too heavy on a plain white cake, but I love thick and dense frostings which this definitely is ๐Ÿ™‚ As far as whipping it, I’m not sure. I would recommend letting it sit for a few hours and then beating it with hand mixers for a few minutes and see if that whips it lighter. I don’t think you want to add more liquid. I hope this helps, sorry I don’t have any definitive answers for you since I haven’t tried using this on a cake… yet ๐Ÿ™‚

        Thank you! That was very helpful!!! And I agree, The thicker the frosting, the more decadent IMO ๐Ÿ™‚ (BTW, I just finished the last brownie and will be making another batch!!! Can’t tell you how much we enjoyed them.)

  8. Nicole says:

    I made these for my husband the other day, and they didn’t last very long. For the frosting I used sour cream instead of milk because I forgot to pick some up, and it worked a treat! I love the crunchy, nutty texture of these! Will no doubt make these again and again????

    1. chelseamessyapron says:

      Awesome!! I’m so thrilled you enjoyed these so much! Thanks for the kind comment ๐Ÿ™‚

    Hi Chelsea!! These brownies were delicious, thanks for posting this awesome recipe!! As I bake almost exclusively paleo, this recipe was fun for me to experiment with! Just FYI, I substituted almond flour for the oat flour, and agave for the coconut sugar (only because there was no more in my pantry!). So those substitutions work great for anyone curious. Thanks again for this great recipe!

    1. chelseamessyapron says:

      Hey Liz! So glad you enjoyed these brownies! ๐Ÿ™‚ Thanks for sharing your substitutions as they are so helpful for others ๐Ÿ™‚

  10. Alice says:

    Chelsea,
    I have a kid who reacts to coconut oil. Is it ok to substitute vegetable oil in your recipes which calls for melted coconut oil?

    1. chelseamessyapron says:

      I’ve actually not tried that substitute in most of my recipes. I know it doesn’t work in my cookies recipes, but I’m really not sure about the breads and brownies. Sorry Alice, I wish I could be of more help!
