Healthy Low Carb Sugar Free Protein Brownies!

protein brownies

I’d attempted making protein brownies once before – they became protein chocolate muffins lol. When I discovered the secrets of making perfect protein cookies with my Shortbread Protein Cookies Recipe, something also clicked for me about making a protein brownie recipe – it needs fat. Low fat brownies are just denser versions of muffins. These healthy brownies are however a bit lower in fat than regular brownies, but there’s just enough fat in there to keep them moist and fudgey, and to keep them from rising like muffins. 

This protein brownie recipe makes very rich, dense protein brownies that almost resemble a fudge. They’re flourless, and both low carb brownies and sugar free brownies as well, and oh so chocolatey! Cocoa powder is very rich in fiber and iron, and it causes your brain to release mood boosting dopamine. These protein brownies will definitely satisfy your chocolate cravings, and maybe make you want to hug somebody. 

INGREDIENTSprotein brownies

(makes 12 protein brownies)
1/2 cup unflavored whey protein isolate
3/4 cup cocoa powder
1 pinch of vanilla powder
1/3 cup butter (room temperature)
1 cup erythritol (or use powdered erythritol for a smoother consistancy)
5 packets powdered stevia
1/2 cup plain greek yogurt
1 egg
1/4 cup egg whites


Preheat oven to 325 fahrenheit. Combine the powders in a mixing bowl. Cream the butter with the erythritol and stevia, then add in the greek yogurt, then the eggs. Then mix the powder mix in with the butter mix.

Line a 8×4 inch loaf pan with parchment paper (optional, but it will help get the protein brownies out later) and pour in the batter. Bake for 30-35 minutes, be careful not to over-bake as they will become dry and crumbly. Wait till they cool, then slice into 12 protein brownies, and enjoy!

  • Hi!! I’m loving your recipe, but where i live we don’t have erythritol.. can that be substituted by more stevia? and if yes, for how many packets?
    and also, can i use cream cheese or acid cream instead of greek yogurt?? will the consistency be similar?
    Thank you so much!

    • Hi Natalia, if there’s any way you can order erythritol online, I would strongly recommend doing that. There isn’t another sugar substitute that I’m aware of that ticks all the same boxes. If you can’t get erythritol, perhaps see if you can find xylitol. It has similar characteristics to erythritol, however it does have more calories. Using more stevia instead may work in some recipes, but the erythritol mimics the “bulk” of sugar in the recipes, so the texture won’t be quite the same without it. Also, I find the taste of stevia on it’s own can be a bit sickly sweet, even bitter. But if you don’t mind the taste too much, you could give it a try.

      Substituting cream cheese for the greek yogurt will work just fine. Not sure what you mean by acid cream though. Cream with lemon juice added?
