Quick and easy to make 4 ingredient healthy protein brownies are moist and fudgy and contain NO SUGAR, NO EGGS, NO OIL, AND NO FLOUR! They are naturally Vegan, gluten-free, and paleo. Enjoy them for breakfast or any time of the day. 
Ever since I started making these healthy protein brownies for my paleo obsessed husband, We’ve never looked back. They are fudgy and delicious and because they are made with all wholesome ingredients, eating them couldn’t be easier. There’s no better feeling out there than enjoying brownies guilt free!
These brownies are great if you are on a low-carb or paleo diet or if you are a weight trainer. They are packed with protein powder, nut butter, and bananas. Since they are mostly banana and nut butter, they make a great breakfast on the go.
For best results:
- I suggest using casein, Vega, or any plant-based protein powder in chocolate flavor.
- For the nut butter, almond, cashew or peanut butter all work really well.
- For the bananas, the one and only rule is the riper the better!
To make the brownies, simply combine all the ingredients with a whisk or wooden spoon until fully combined. Pour (or press) better into a greased skillet or small pan. Bake for 18-20 minutes and cool before slicing.

I cooked it for 40 minutes and it still wasn’t cooked through. I didn’t like the taste either.
What can I replace for the protein powder for normal dietary? Can I use flour?
Can I swap cocoa powder for cacao powder??
Yes, that should work!
What if I don’t have any protein powder?
I used six large bananas, added 2 eggs and 1 tsp. baking powder, everything else the same as above and cooked for 25 minutes – REALLY good. Thanks!!
I would like to see the nutritional values please. Did you forget it?
Thanks
These were very good, although they did not have the crispy flaky tops that yours do in the photo. Maybe it’s because I used a hand mixer instead of stirring it with a whisk and/or spoon. I used almond butter, Vega Vanilla Proteins & Greens (because that’s what I have) and 7 small bananas (because I didn’t want to throw any out.) It tasted too banana-ey so I added another 1/4 cup of cacao powder (1/2 cup total) and 1/2 tsp sea salt + I sprinkled some salt on top. I baked it for about 23 minutes in a cast iron skillet. Maybe I should have baked it a little longer, but my husband insisted it would continue to cook in the cast iron. The texture was very silky, rich and decadent. I cut it in 12 slices and served it with fresh raspberries. Next time I’ll cut back on the bananas a little and try it with peanut butter. Thanks for the recipe!
This was surprisingly good and my kids enjoyed it. Will make again when I have bananas coming out of my ears. I added 1/3 c. cocoa and a handful of walnuts and chocolate chips.
Do you have The nutr information for these brow?
Made these vegan wiTh arbonne chocoLate protein powder, almond butter and sweet POTATOES INSTEAD of bananas (DIDN’T have bananas today). Yummy!
After 30 minutes of baking, I could never get it to set. Even after 30 min of baking, and 10 minutes resting, its still the consistency of a mousse. 🙁
Tastes decent, though.
Add 1-2 eggs
I made these In a pan no a skillet anD they are grainy and kind of gross. Other than that, i followed the recipe exactly. What am i missing??
I followed this recipe and the brownies were grainy. I could not serve them to my family.
Is your protein powder grainy? Make sure to use a very powdery protein powder
since I don’t have chocolate protein powder, can I use vanilla and reduce to 1/4 cup, and then increase the cacao powder to 1/2 cup?
I have not tried that alteration so I can not recommend it but please do let us know if you try it out and how it works out for you!
GReat heAlthier alternative to brownies! I used CarAmel machiato Soy PROTEIN powder and tastes great. Not too SwEet! Going to use As a post gym Snack 🙂
Is there something I could use instead of cocoa powder
Carob powder is generally a good substitute for cocoa.
Can i not use the protein powder and would it STill work??
These are wonderful. They’re even in consistency and didn’t taste grainy like i suspected they might. These brownies are a pleasantly convenient surprise.
do you have the macros on these?
Can i sub pumpkin for the banana and aDd a sugar free sweetener?
Does anyone know how many calorieS are in this?

thank you for this recipe! I Have made it so many timeS. Its the Best way to use up Very ripe bananas and the inGredients are so simple. I Just made a batch and added carob chips and chOpped walnuts. Yum!
I made these yesterday and they are SO AWESOME. i really like all the heathy ingredients. The only thing i will change is next time i will add 1/2 cup of cocoa powder because they needed more chocolate flavor to me. I will be making theses often. Thank you for this great recipe!!!
Or would you suggest doing 1/2 cup of protein powder instead?
Cooked them for 35 minutes and took them out because I was worried I would overbake THEM. They are the consistency of paste and about the only flavor you can taste is BANANA. Not something I would make again
love Them! Though, i am not a vegan or anything Else along those lines, (i am a white meat Eating kinda Being), but i have endometrosis which somewhat forces me to leaN more toward a diary, soy and gLuten free tyPe of diet. So, this recipe iS right for my body, and We (my husband and son), really ENJOYED tHese. Great Protein intake. ThOugh, i wish I knew the Macros on this Recipe.
I used chOcolate flavor hydroLyzed whey protein, whiCh i know whey is daiRy. But, my Vegan protein is too chalky. Besides i wasn’t going to deprive my Husband and son from a delicious protein when I can cheat a little On my endo-diet. I also added 2 tablespoons of unsweetened applesauce just for kicks. It’s a Great idea, just saying.
Overall, Great recipe, taste great.
Hopefully, i can figure out the mAcros for each serving!
Enjoy!!!
What would adding egg whites do to the recipe? I am not vegan and am considering adding egg whites!
If you add egg WHITES add 1/2 c and I would also add 2 tsp of baking powder. I assume you want it to be fluffier so adding the baking powder will help accomplish that. If you try it let me know how it goes! I may try it too.
I tried thie egg whites and 2tsp baking powder. It worked really well! Baked in an 8×8 glass pan for about 40-45 minutes so it cooked all the way through and set. I used unsweetened rice protein and natural almond butter. I like this version better than the original recipient which I made many times.
I really liked these. All of my overripe bananas were in the freezer so I just defrosted a bunch and then mixed in the other ingredients with a fork. I baked them for 18 minutes at 350 and they’re great fudgey brownies.
I believe the author meant that it could be made vegan by using the appropriate protein powder. Choose the one that works for your diet needs. Also, as others have mentioned, true natural peanut butter does not have sugar added. And of course bananas have sugar. I am sure the author meant no added sugar.
