Four Ingredient Flourless Protein Brownies

4 Ingredient flourless brownies packed with protein and 100% guilt-free! These gooey and fudgy protein brownies are your new post-workout snack! 

After a heavy workout, I often enjoy flourless protein brownie bites, homemade protein bars, and these fudgy protein brownies

Fudgy Protein Brownies

Are protein brownies good for you? 

Not often do you hear a recipe with the words brownies in it healthy, but these are good for you!

Made with healthy and wholesome ingredients, they are PACKED with protein (over 68 grams in the entire recipe!) and contain healthy fats and are super low carb.

Unlike commercial protein brownies (store-bought ones!), these have no fillers, no additives and take 20 minutes to whip up.

Can I add protein powder to baked goods?

When it comes to using or adding protein powder in baked goods, you need to be incredibly careful as to what brand, type, and consistency you use.

I must admit, I’ve had MANY failures in which the successful result was achieved by simply replacing the protein powder used. There is the assumption that baking with protein powder results in hockey pucks or a hot (non-edible) mess. 

Whey Protein Powder Brownies

From experience, I do not recommend using whey protein powder for any of my recipes. Whey tends to make the batter extremely liquid-like but once it is cooked, it becomes dry and brittle- not something we want in a recipe.

Instead, I trialed this with 3 different types-

All three options work, but only the vegan protein powder produced the crackly tops that you find on fudgy brownies.

To ensure you achieve this crackly top, sprinkle some granulated sweetener on top (either coconut palm sugar or another granulated sweetener).

Best Protein Brownies Recipe

These flourless protein brownies need just four ingredients to whip up! They are rich, soft and decadent, you’d be fooled into thinking they were actually healthy!

Protein Brownie Ingredients

Unlike traditional brownies, these contain no butter, flour, sugar or oil. Instead, a combination of mashed fruit (or vegetables), nut butter and protein powder gives it the extremely dense and creamy texture! 

Unlike traditional brownies, these fit ALL the major diet groups- They are 100% paleo, vegan, gluten-free, keto-friendly and super low carb!

How to make fudgy protein brownies from scratch

You’ll start by adding all your ingredients into a high-speed blender or food processor. Blend the ingredients together very well, 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 still hot in the pan, lightly press your hand over the top, to form un-natural cracky tops. 

Allow the brownies to cool in the pan completely, before drizzling with chocolate and slicing up.

Ingredient Substitution and Swaps

To lower the carbs and make these brownies keto-friendly, swap out the banana for mashed pumpkin. If you do opt for this, be sure to add some sweetener to it (keto maple syrup, liquid stevia etc).

Swap out the almond butter for any smooth/drippy nut butter- Peanut butter works great. Keep it nut-free by using sunflower seed butter.

Want to leave out the protein powder? Make these brownies instead. 

How to enjoy protein brownies- Storing and Freezing

These taste 200% more amazing once cooled and refrigerated. I swear they get so much more dense and fudgy, it takes it to another level!

Store leftover protein brownies in a sealed container in the fridge. Leaving them at room temperature will see them spoil easily. They will keep fresh for at least 2 weeks.

Protein brownies are freezer friendly and can also be stored in the freezer. Place wrapped brownies in individual ziplock bags or place them all in a freezer-friendly container. 

PS- These protein brownies are great for kids, so throw a few in a lunchbox or as an after school snack!

  • Preheat the oven the 180C/350 degrees, grease a square pan with parchment paper and set aside.
  • In a blender, food processor or large mixing bowl, combine the bananas, cocoa powder, protein powder, and almond butter and blend/mix until smooth. Fold through chocolate chips if using them.
  • Pour the mixture into the greased pan and bake for around 18-20 minutes or until cooked through. Remove from the oven gently press down with your hands to create crinkly tops. Allow to cool before drizzling with chocolate and slicing.


I do NOT recommend whey protein powder- It lends itself to a gummy texture.
You don't need to blend or process all ingredients, but they lend a smoother texture- Although I do like my banana chunks in them
These brownies are not super sweet, as the protein powders used all had sweetener in them. Adjust accordingly if you'd like a very sweet brownie.
Brownies are best kept and enjoyed refrigerated- They are also freezer friendly.

  1. Yay- I loved the originals, but these crinkle tops are my favorite thing to see on a brownie. I wonder if my soy protein would work? I’m so clueless when it comes to protein powder. .

    1. I’m going to try my Arbonne protein powder (that’s what I searched in Pinterest for this to pop up), I know they use brown rice and pea protein so fingers crossed!!! I’ll be making them with my almost four year old daughter!

        1. Hey! Okay I tried responding on my phone last time but that didn’t really work….. We did end up using that brand of protein and it turned out amazing! Although I forgot to mix the nut butter in beforehand so it was quite marbled, but that’s okay. We (meaning I) ate the brownies way too fast, to take pictures, but we’ll be making them today and will update with a picture if you’d like! Thanks. (Oh and good luck on the book deal, that’s great news!)

      1. I am using Arbonne as well so this is great to know! I actually haven’t used mine in a shake yet because its so perfect for baked goods. Thanks for sharing!

  2. Brownies without cracked topping just aren’t brownies! I really should try this refrigerator trick of yours…you’ve been loving on that lately! Brownies for the win! Can I have brownies for breakfast?

  3. Dear Arman, These protein packed brownies look wonderful and I love that you made them with bananas. Such a great snack to have on hand. Take care my friend, Catherine

  4. Okay, it’s not that your other recipes hadn’t looked good, too, but this one takes the cake, no, brownie ;). For years, I assumed the crackly crust was the result of the caramelized sugars from the refined kind and melted chocolate in traditional recipes. And now you’re giving proof caramelized banana sugar is working this magic, too?! I’m impressed. Did it take you a lot of trials to get the results you were going for here?

  5. I just made these and they are very good! I made mine with a vegan protein (Vega brand) and didn’t get the crackle. I think to get the crackle top, everyone would have to use the same type of powder you did. Still delicious, though!

  6. I just found your blog (literally 20 minutes ago) and there’s already so many recipes I want to try. I’m gonna start with these though. They look magical.

  7. Yummy! Just finished baking these 🙂 I added some walnuts on top!
    Thank you for the recipe I’m going to re-use this; It was simple, quick, and healthy

  8. HI! I’m thinking of trying this with the hemp protein powder I use. How much would you say ‘2 scoops’ is for someone who doesn’t have that protein powder scoop? ? Thanks!!

  9. I find brown rice protein powder to lend the BEST texture in baking! So delicious and fluffy! But WHY OH WHY OH WHY do I have to wait overnight for the best results?!?!?! BOOOOO! LOL just kidding but I am not patient when it comes to these things! Will definitely make this recipe!

  10. Hi,

    Your recipes look amazing. Unfortunately many of them claI’m to be Paleo on pinter est but they are not. There are no grains on Paleo. It’s a bit misleading.

  11. Is there a way to make them without peanut butter or almond butter? Would something like coconut oil work? I want too make them for my mom but she is allergic to peanut butter and doesn’t like almond butter

  12. I think I speak for everyone, ok, I speak for me, when I say you and your recipes are the answers to our prayers/wishes/miscellaneous meditations :). I made the flourless pumpkin blondies and they were the perfect light dessert for Thanksgiving. I am definitely going to make these very soon. Definitely.

  13. I made your brownies today, 4 ingred, but added an egg for protein and to make them more cakey. They are super dry, do you think the egg did that, or what ingred should I increase for moistness?

  14. I used a blend of hemp and pea protein powders and didn’t get the crackly topping. They smell great and they’re cooling now! I can’t wait. I’ll try out the rice protein powder next time. Thanks for a great recipe!

  15. These were delicious. I used chocolate vega protein. My kids loved these. I didn’t need to melt the pb though and I just mixed it by hand because I was too lazy to clean my blender. They turned out great. Thanks for the recipe!!

  16. I made this recipe for two reasons, it was the top Google choice and I had all the ingredients. Holy tasty brownie batman!!! Not only was it great out of the oven but it kept getting tastier in the fridge. I will try all of your recipes now! I have a horrible sweet tooth that leads to bingeing; these satisfy my sweetness and fill me up. Thank you so much!!!!

  17. Must make ASAP! How many servings did you get? I ran the numbers using 2 scoops Sunwarrior protein powder and found I can only make 5 servings to get 15g protein per brownie. I might just make 6 or 7 to get a few more out of it. Can’t wait to try.

  18. How do you think the Orgain Organic Protein plant based powder would work (in creamy chocolate fudge)? That’s the only one I have, it has sprouted brown rice protein, chia protein, hemp protein, and fiber. Brownies are my life, but I don’t want one’s with all the sugar or the super hard healthy recipes I can find online, but your brownies sound perfect!

  19. Hi Arman, I made this with Nature’s Plus Spirutein protein powder, chocolate flavor (though heat kills the spirulina) and they came out great. Thanks!

  20. Do you think you could sub coconut or almond flour for the protein powder? I’ve just started a paleo-ish diet and I don’t have protein powder thanks!

  21. Hi Arman,
    This might have been asked already but you have so many comments to read through.. I’m really not into protein powders, could you give me any recommendations on replacing it with brown rice flour? As you suggest that the vegan brown rice powder works best. 🙂

  22. So I just read a comment from you a couple of comments up from mine which makes me think you used casein protein powder in the ones pictured. But in the post you say you used the brown rice one. Using casein protein powder would explain the volume and crinkle top that were not achieved when I used your brand of brown rice protein.

  23. OH my gosh I can’t wait to try some of your recipes!! Thank you for taking the time to post these! Now, if they could just be calorie free…?

  24. Just made these, here is my nutrition estimate from a 8×8 pan, 9servings—YMMV 110cal, 6carbs,6protein. I used half almond butter/half pnut butter because I had about half the required almond butter that I needed to use up. This recipe is a saver. OH and I added about 3T choc chips.

  25. Is shakeology considered a whey protein – would it work for this recipe? I have a bag I got burnt out on drinking and would love to use up in this recipe. Sounds amazing!!

  26. Made these with 1 scoop of Plant Fusion Vanilla, about a 1/3 cup of cocoa powder, salted almond butter and the 3 bananas. Added a dash of vanilla extract and pink Himalayan sea salt. INCREDIBLE! Thank you for the recipe 🙂

  27. I absolutely love being able to get extra protein in my diet in the form of protein powders; casein in particular. But a few years ago I became sensitive to the sweeteners they use in Optimum Nutrition Casein. They were the purest I could find, and I still use their creatine but had to stop the protein. Now I eat heaping piles of plain Fage greek yogurt three times a day : ) I’ve searched everywhere for a pure protein without added fake sugars. I checked out the three that you posted and it looks like they all have the artificial sweeteners. My question, since you seem to know about the healthier protein mixes available is this: are there ANY out there that don’t have artificial sweeteners or stevia? I thank you in advance for any information! Even if it is bad news of not having any protein powder options!!

  28. Hi Arman,

    Love your blog! These brownies look fudgy and delicious. I cook healthy food for my family but I have not baked healthy. I think I should start baking healthy now 😉

  29. Hey buddy thanks for the recipe! Mine didn’t come out nearly as good as yours but they were decent after a workout. I used 2 scoops Garden of Life Raw Protein Cacao and almond butter as suggested. Were you able to get a nice texture/crackly top with other protein powders besides what you linked? For some reason I think using peanut butter has something to do with the crackly top. How much protein and banana did you add exactly because I added a cup of mashed banana and it seemed too much. Ugh I just want to get this right but it seems the recipe leaves too much room for screwing it up. All your help is appreciated.

      1. Thanks for the reply. Yes I read the directions completely but I was hoping for more accurate measurements. For example the difference between 1 and 2 scoops of protein powder can give quite different results. Also with the bananas my 3 medium bananas came out much more than 1 cup. I’m wondering if that is why my brownies didn’t come out as good as yours. Also did you have luck getting crackly top with almond butter? Thanks again for your help.

  30. Do you happen to have a shot of how the brownie batter is supposed to look or maybe a video? Also, are there any alternatives to protein powder? My powder didn’t come with it’s scoop so I’m trying to figure out what the measurements are for those. I only have the hemp protein powder right now, and they didn’t turn out well for me using that

    1. Hi Kevin- No, I don’t have a video sorry. In regards to the protein powder, the scoops are usually 32-35 grams each. As for the alternatives, you could try my original 3 ingredient flourless brownie recipe- It omits the protein powder all together 🙂

  31. I just made these brownies using a glass baking pan and chocolate WHEY protein powder my trainer distributes and although I didn’t get the crackling top they turned out FABULOUS with the whey. I couldn’t wait til they cooled to try them and they were so deliciously gooey

  32. Used Chocolate Protein & Greens powder, some pumpkin puree, a mixture of various nut and seed butters, and 1 Tbsp Hershey’s Special Dark Cocoa powder and 1 Tbsp Cacao powder. Baked it in an ungreased glass loaf pan and worked like a charm. I love them!! Great recipes 🙂

  33. The recipe says “1-2 scoops of protein powder (see above content for tested recommendations)*… so how much exactly should I use???

  34. Sorry, not a fan. These weren’t even remotely sweet. Anyone who tries this add some sugar, honey, brown rice syrup, anything. And they don’t look anything like the photo.

  35. Have you tried pb2 and water instead of regular peanut butter? I don’t have any of the regular stuff on hand and I want these TONIGHT!!!!

  36. What do you think it will turn out like if you used eggs instead of the peanut butter? My partner is allergic to nuts so I’m not sure what to use!

  37. Hello! I noticed you mentioned 2 other protein powders, would those work just fine as well? But maybe not top quite as crackly? I am looking knot purchasing the paleo brand you mentioned.

  38. Oh my goodness these are amazing!! Followed your directions closely, refrigerated them overnight and my son and his friend had them for breakfast & raved about there yumminess…if that’s even a word:)) I just ate one and there so good it feels like a naughty treat, but they’re so good for you! I used Vega One protein and greens vanilla flavored 1.5 scoops, almond butter, 3 very ripe bananas and 1/4 cup Hershey’s sweet dark cocoa powder….yum!!!

  39. Could I use Bob’s Red Mill Soy Protein ? If so do I have to add additional sweetener. It is not flavored and has no sweetener in it. I have been looking for recipes to add this protein powder to. Thank You

  40. I was wondering if any one has used creatine powder and if it worked? I am sorry, I don’t know much about protein powders but these look good and I like that they are healthier than regular brownies.

  41. I tried this recipe and despite the fact that I SLIGHTLY overbaked the brownies, I believe that the main reason for their failure was the egg protein powder that I used. They turned out extremely hard and rubber-like.

  42. Made them a couple of days back. They were so amazing. I watch my carbs and sugars as I am pre diabetic. This is a perfect recipe. Didn’t spike my blood sugar. Also, my 5 year old daughter loved it too. Will make them again. Thanks a million for this recipe.

  43. These are DELICIOUS! I used my QUEST chocolate protein powder and instead of using nut butter I substitute it with PBFit. High Protein and Low Fat. Taste Great!

  44. I used sunflower seed butter, special dark cocoa powder, bananas, and hemp protein powder…I also baked in a 6×9 and it turned into this amazing chocolatey cake from the gods. With…you guessed it…a perfect crackly top! Thank you SO MUCH!

  45. Hi there,

    I tried making these but for some reason mine came out with an overpowering taste of bananas. It tastes almost like banana bread. I used 3 bananas and it was close to 1 cup and a quarter. Should I use less bananas?

  46. 2 T – 1/4 cup cocoa powder means 2 cups + ¼ cup? Is that exact? Thanks! It looks soooooo goooood! Can’t wait to do the recipe!

  47. These look amazing. I’m just not a huge fan of bananas — does the flavor of bananas survive in the final product, or do you just taste chocolate-y deliciousness?

  48. I’m allergic to all nuts, so what can I substitute for the nut butters? Would love to make these, as a celiac I can’t eat much of anything.

  49. Tried with a pea-protein based protein powder. Didn’t work well for us *this time*, but I think I might have overcooked it, which might explain why it didn’t become ‘fudgy’ in the fridge. To eat these, we put an orange flavored icing on top – not ideal….. Plan to try again.

  50. I just made these with a scoop of pea protein powder and a scoop of Greek yogurt protein powder. They are kind of meh and I can taste too much of the banana. Maybe apple sauce might work better. Thanks for the recipe though!

    1. Just want to update my earlier comment, which was for the brownies while still warm. They are much better cooled! I left them covered while I went out and now that they are cool the banana isn’t overpowering and the protein powders aren’t too noticeable. I think I would up the protein powder a little bit to see if they would be a bit less soft next time.

  51. Wow! These brownies were amazing! I didn’t get the cracked top on top of mine though. I’m not sure what kind my protein powder was, but they still tasted awesome! Definitely a number one go to in my family. Thanks for this.

  52. Are there any other protein powders that will produce a cracked top? I have a deadline in baking about 50 protein brownies for a sports team, and I don’t think any stores near me carry the vegan rice powder 🙁

  53. Hi there, I’m trying this from the UK… What measurement is ‘a scoop’ (for the protein powder). I have the American cups but not sure what the scoop refers to. Is it like a tablespoon? Thanks ! Can’t wait to try this receipe!

  54. I made these and they were awesome. I used optimum nutrition chocolate protein powder (whey, against the advice here) and they turned out fine. I also added a little honey to sweeten it up. I cut it into six pieces and they’re each about 220 calories with 10 grams of protein.

    Thanks for the recipe!!

  55. Made these today with crunchy peanut butter, hemp protein powder and organic cocoa powder. Wow, they are just fantastic! So easy to make and such a delicious pre-workout snack. Thanks for sharing the recipe.

  56. These were delicious. I did use applesauces instead of bananas. Not my plan but when mixing up realized I was out of bananas. I will use bananas next time as probably choc goes better . Don’t really taste much of the applesauce but did turn out and is good. Thanks for a great recipe.

  57. Hi! What’s the role of the nut butter in this recipe? I’m thinking of using Better’N nut butter as oppose to regular peanut butter.

  58. Thanks so much for the recipe.
    Made it with whey protein choc flavour and choc peanut butter, raw cocoa and it was perfect. Love it
