I’m so excited to share this healthy protein brownie recipe with you today! I’m also sharing tips for baking with coconut flour and protein powder, because there’s a little bit of a learning curve. Lately I’ve been experimenting a lot with baking with coconut flour and almond flour, reducing our sugar intake, and sneaking in a little whey protein into our snacks. I’ve always loved baking, but switching to these new ingredients has really thrown me for a loop because they change the flavor and texture of food quite dramatically! A lot of the coconut flour and almond flour recipes I’ve tried from Pinterest turned out to be gritty, disappointing flops. So I decided to just start from scratch and develop my own recipes, like my zucchini brownie recipe with protein powder. I came up with that brownie through a lot of trial and error, adapting an old zucchini and date cake I used to make, but ultimately changing almost every ingredient! It turned out to be so delicious and moist and sweet – it was the breakthrough I needed to keep experimenting!
Today’s protein brownie recipe is another healthier brownie option, with avocado, protein powder, coconut powder and a touch of sweetness from a homemade fruit sauce and brown rice syrup. I’ve been trying to add more low sugar recipes to my cooking and baking repertoire and this one is a keeper!
Ingredients for this Delicious Protein Brownie Recipe:
- 1 ripe avocado
- 1/2 cup fruit – I used mango, peach & strawberry*
- 3 eggs
- 1/2 cup brown rice syrup (this is the exact brand I used)
- 1/2 cup coconut flour (this is the exact brand I used)
- 1/4 cup whey protein powder (this is the exact brand I used)
- 1/2 cup cocoa powder
- 1 tsp baking soda
- 1 tsp vanilla
- pinch of sea salt
*For this recipe, I made my own quick fruit sauce using frozen mango, peach, and strawberry mix. It added a nice, soft flavor but not as much sweetness as a ripe banana or even unsweetened applesauce lends baked goods. I want to try this with different fruit combinations – imagine the cocoa paired with a homemade raspberry sauce! Of course, you’re welcome to substitute with 1/2 cup of applesauce, mushed bananas, or whatever soft, pureed fruit you’d like.
How to Make a Protein Brownie Batch:
- Cook the frozen fruit for a few minutes to boil off some water.
- Combine the peeled avocado, fruit mixture, brown rice syrup and vanilla in a food processor until pureed.
- Pour into a large mixing bowl and whisk in the 3 eggs.
- Sift the coconut flour, protein powder, cocoa, salt, and baking soda (don’t skip this step!)
- Stir the sifted mixture into the avocado mixture and combine thoroughly.
- Pour into a greased, 8×8 pan.
- Cook at 350 degrees for 25 minutes (your oven may vary).
- Remove from oven and let cool for 30 minutes.
- Store in a covered container in the fridge once cooled for maximum freshness!
3 Tips for Baking with Coconut Flour and Protein Powder
- I’ve been baking a lot with protein powder and my best tip is to sift, sift, sift. Whisking the coconut flour, cocoa powder, protein powder and baking soda is a key step
in achieving a smooth, velvety brownie. If you skip this step, the protein powder and coconut flour want to clump and you’ll end up with pockets of dry flour in the baked brownie. - Add cocoa powder! My biggest complaint with coconut and almond flour is the texture, but recipes with a lot of cocoa powder have a more familiar, velvety smooth texture thanks to the fine cocoa powder.
- Add more eggs! If you’re experimenting a little on your own, trying to adapt old recipes to be grain-free, take a look at how many eggs coconut flour recipes have – lots. Don’t be alarmed if you need more egg!

I am absolutely in smitten with this healthier protein brownie recipe! They are dense but soft, with a chocolatey richness. The protein powder and avocado make them filling and deeply satisfying as a snack or healthier baked dessert.











They look yum Tanya!! Seriously, what can't you do!:)
Thanks! Maybe one day I should share a post with all of my failed DIY projects and inedible recipes, lol. I tend to only share the highlight reel here 😉
I may have just licked my computer screen … these look so good! x
Haha! That's such good feedback. Sometimes I'll be looking for a recipe online and, I swear, I start to drool a little…
Thanks Tanya, your recipe looks really good; I just purchased Sarah Wilson's cookbook so I'm excited about lots of her recipes too.
Which cookbook did you buy? I only have her sugar detox/cookbook combo but I think she has a couple others. You'll have to let me know how the recipes turn out! If it's a different book than what I have, I'd love to hear some feedback!
I love having sugary snacks when I'm on the job, but I always end up crashing a half-hour later. These sound PERFECT! And I'd never thought to include protein powder before. That's kind of brilliant. Thank you, Tanya!
Happy to help, Matt. You can sneak in some protein powder into any of your favorite sweet snacks. My diabetic dad even mixes some into his oatmeal so it's more filling, for longer.
