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. 4 Ingredient Fudge Protein Brownies (Vegan, Gluten-free, Paleo)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 caseinVega, 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!
    4 Ingredient Fudge Protein Brownies (Vegan, Gluten-free, Paleo)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. 4 Ingredient Fudge Protein Brownies (Vegan, Gluten-free, Paleo)

    What would adding egg whites do to the recipe? I am not vegan and am considering adding egg whites!

    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.


    I really like these . I made them with Bob reeds unflavored whey protein powder instead of choc powder. I don’t care for flavored protein powders. Kept the rest of the recipe the same and baked in a glass our dish for 18 mins .They turned out great. I’m going to try with reconstituted powdered peanut butter to cut some calories and fat.


    Love the idea of cooking these in a skillet! Looks absolutely delicious. ❤️


    I just made these for the Super Bowl , my daughter and son in law are coming over and both have gone Gluten free and my husband and I are watching our calories and trying the more cleaner diet, I used my husband Whey protein, chocolate peanut butter flavor powder, and they did take like 40 min before they where done, but they aren’t bad at all, you have to remember they are not old fashion brownies, they are a healthier protein brownie, so with that in mind they are pretty good , 😊 thank you for a healthier way to have a treat !!!!!!!


    I absolutely love these! I wish peanut butter had fewer calories…but such is life. I was thinking of ways to try to substitute it out. I am no baker or anything so maybe these won’t let the brownies set up properly. Maybe you have a few suggestions?
    1. Mix PB2 with greek yogurt?
    2. Mix PB2 with unsweetened apple sauce?

    Great recipe though! Thank you!


      Wonder if the dry peanut powder (reconstituted) would work? I use it in my smoothies because its less calories and fat. But havent baked with it. I’m going to try it.


    Took 1.5 hours to cook all the way through.


    Making them now. I used pb2 chocolate pb (powder) instead of regular pb…guess we will see how they come out


      How did they turn out ?? Thought about using peanut butter powerer too


      Oh!!! So curious about this! How did they turn out?


    I LOVED THESE!!! I used QUEST baking protein. Thanks for posting.


      Will be sure to try quest next time I make a batch. I’m glad you enjoyed them 🙂

    My boyfriend and I didn’t love it, but we didn’t hate it either. I have a horrible sweet tooth and this is an alternative to the regular brownie. Might do a bit of tweaking with the recipe next time.


    Casein is not vegan


    exactly, casein is milk protein


    She didn’t say it was vegan. She said to use Vega to make these vegan. Read the post.
