These protein brownies are super fudgy, gooey, and need just four ingredients to make! No flour, no eggs, and no butter needed, they make a guilt free dessert fix.
As someone with a raging sweet tooth, getting my chocolate fix in healthier ways are always a plus.
This is why we regularly make healthy chocolate cake or brownie bites. They are rich and chocolatey but made with wholesome ingredients. When we are in the baking mood and want brownies, nothing beats these fudgy high protein brownies!

Why you’ll love this protein brownies recipe
My protein mug cake recipe inspired these brownies. It’s essentially a single serving version but as someone who enjoys this so often, I need a big batch! These are a staple in our kitchen and I have no doubt they will be in yours, too!
- They need just four ingredients. Bananas, cocoa powder, almond butter, and protein powder.
- Each brownie has 12 grams of protein. Not only do these brownies satisfy the sweet tooth but they also keep you fuller for longer.
- You can add even more protein! If 12 grams isn’t enough, you can double that by spreading a protein frosting over the top (check the recipe card for the details!).
- Naturally vegan and gluten free. These are great if you can’t eat eggs or flour.
How to make protein brownies
The beauty of making these high protein brownies is that everything is thrown in a blender, bowl, or mixer to create a batter. All you do then is bake it up and you are done!
- Almond butter. Smooth and creamy with no added sugar. I either make my own or opt for a no-stir kind.
- Banana. The riper the bananas are, the sweeter the brownies will be.
Banana substitute
Not a fan of banana or allergic? Swap it out for equal parts pumpkin puree or unsweetened applesauce. However, you will need to add some sweetener or syrup to compensate for the lack of sweetness.
- Cocoa powder. I like using dark cocoa powder for an extra rich flavor, but any cocoa powder works.
- Protein powder. Using a chocolate protein powder will yield the best flavor but vanilla will also work.
- Mix-ins. Optional, but I love to add some chocolate chips or chopped dark chocolate.
Start by adding all your ingredients into a high-speed blender or food processor. Blend the ingredients together until fully combined. If desired, add some chocolate chips.
Then, transfer the batter into a lined pan and bake for 15-20 minutes, or until a skewer comes out ‘just’ clean. While the brownies are hot in the pan, lightly press your hand over the top to form unnatural cracky tops.
Allow the brownies to cool in the pan completely before drizzling with chocolate and slicing them up.
Tips and tricks
- Use the right protein powder. Not all protein powders are equal. Casein, brown rice, and pea protein powders are far superior to whey or whey protein blends. Whey based powders tend to dry out baked goods.
- Make the brownies sweeter. These brownies rely on the banana and the sweetened protein powder for sweetness. Add a few tablespoons of sugar or maple syrup if you prefer sweeter brownies.
- Do not overbake them. Once the brownies are firm on top and a skewer comes out mostly clean, they are ready to be removed from the oven.
- Add mix-ins. Like any good brownie, these are a blank canvas, so fold through some chocolate chips, walnuts, or even candy!
- Frost them. To take these brownies to another level, add a layer of sugar free or healthy frosting to them.
- Make protein brownie bites. Instead of baking them in the square pan, bake them in a muffin tin for a protein-packed version of brownie bites.
Storage instructions
To store: Leftovers should be stored in the refrigerator, covered, as they will spoil at room temperature. They will keep well for up to five days.
To freeze: Place the brownies in an airtight container and store them in the freezer for up to 6 months.
Recommended tools to make this recipe
- Square pan. The perfect size to bake thick and delicious brownies.
- High speed blender. I love using a blender over a mixing bowl because there are no traces of bananas whatsoever.
- Food processor. Use the handy dandy food processor if you don’t have a blender.
Frequently asked questions
Compared to traditional brownies, high protein brownies are healthier, as they contain less sugar, less carbs, and added protein.
Adding some almond or oat flour will give these brownies stability and structure but aren’t necessary.
To get the crackly tops, you need to press down on them once removed from the oven. They do not occur naturally.

Yesss I love brownie bites! If I ever get dessert cravings, I usually only want a couple bites, so mini brownies are perfect for this. Trader Joe’s makes my favorite kind, but these are obviously much better for you. Only thing missing is the sea salt on top! 😉
I LOVE the TJ’s ones. I will send you a salt shaker to enjoy this with 🙂
Wait. Good things come in small packages? I thought good things came in large packages? Like ridiculously oversized packages. Like a ridiculously large box fill with these mini-muffin brownies. Just imagine how awesome that would be! Love the way you mixed it up and changed the shape of these bad boys. Sounds quite tasty, mate!
Haha, total cop out but hey, mini is better with brownies!
My brownies came out extremely flat?????
Brownie bites?! How waesome. I used to eat the costco ones but they are’nt nearly as good for you as these ones are! good work!
Thank you, hope you try it out!
Brownies are my all-time favourite dessert! These look delicious – and I can’t believe they have both banana AND protein powder in!
😀 Right? I now look at bananas in such a better light!
I’m currently addicted to “bites” of all sorts. I mean, they’re teeny so you can eat thirty million. And YES to straight from the freezer. So good.
Right? YES! I preach that in most of my recipe posts to everyone, it’s a game changer!
What? Who’s not a fan of bananas? I call shenanigans.
I should forward you some of the hate mail!
I am allergic to bananas and very much appreciate your alertnatives for this recipe! Banana allergies are more common than most think and is a cross reactor for those with latex allergies.
Absolutely! It is so common! Hope you enjoy these, Nina!
These are beautiful– they look so much like a regular brownie! I steer clear of most vegan protein powders because I am allergic to soy and peas, and pea protein is usually in those blends– but the rice one I could try! I use whey in my smoothies, and you’re right– it’s awful in baked goods!
You should try this one- It’s really good, and works well in baking 🙂
Guilt free brownies? Count me in!
Thank you, Sue!
Can you make full brownies with this? I just need brownies lol
Absolutely! 🙂 The original recipe stemmed from full brownies 🙂
These look SO good!
Thank you! 🙂
Do you think these will work with Pea Protein? I’ll give it a try!
Hi Aly! I think it should work- I’d love to hear your thoughts once you’ve tried it out 🙂
Should we use the Vanilla or Chocolate version of the vegan protein powder?
Hi Tania! Either would work- I prefer chocolate for this one 🙂
My daughter has like 10 billion food allergies could I make this without the protein powder
Hi Rebecca- You can make my 3 ingredient flourless brownies- It’s the same recipe, minus protein powder 🙂 Enjoy!
I have never bought protein powder. Is there a standard sized scoop that comes with it? If not could you give a Tablespoon measurement? I have also never used muffin tins that are not teflon. Is it necessary to grease those so the liners won’t stick? And what kind of grease, oil, butter, spray, or Crisco works?
Hi Nina! Any grease will work and the protein powder is usually 32-34 grams!
Loving the combination of banana and almond butter 🙂 Will definitely try this out sometime!
Fantastic- Hope you enjoy them, Lam! 🙂
