[convertkit form=977197]

I created this easy protein cookies recipe back in 2012. They are high in protein, contain no flour and make great before or after workout cookies aka snack. And a great late night couch snack without the guilt.

If you ended up on this recipe in the evening looking for a healthy treat, know you probably have all ingredients on hand to make the best protein cookies in the world! I promise store bought protein bars don’t come even close. Especially in nutrition.

How Do Protein Cookies Taste?

A million dollar question.

  • Cookies are sugar free and naturally sweetened with banana
  • Pleasant soft texture.
  • Not crunchy outside like traditional cookie because no butter baked with sugar. But…
  • Even kids love these homemade protein cookies.

How Many Grams of Protein Is in a Cookie?

Recipe makes 12 small cookies or 12 large cookies. Each cookie contains 6 grams of protein. As well as 11 grams of carbs and 4 grams of sugar. Compared to a regular cookie, these are high protein and low sugar cookies. Just think about it!

How to Make Protein Cookies

1. Mash Bananas

What type of bananas are the best?

Riper the bananas, the sweeter protein cookies.

  • Ripe bananas – yellow.
  • Very ripe bananas – yellow with brown spots.
  • Going bad bananas – brown.

Can I use previously frozen bananas?

Yes. Every time I see banana gone bad, I stick it in the freezer. It gets even more ugly and brown in there. Thaw it and use.

2. Add Wet and Dry Ingredients

Add whey protein powder, oats and peanut butter.

What whey protein powder to use?

Quality Wise

I recommend whey with minimum ingredients, at least grass-fed, preferably organic.

Flavor Wise

  • Unflavored
  • Vanilla
  • Cookie dough
  • Peanut butter
  • Chocolate

In reality, any whey protein powder will work. End taste will vary slightly depending on protein’s ingredients. I used unflavored whey.

Can I use plant based protein powder?

No. Whey protein powder is made from cow’s milk and almost melts with other ingredients. It makes protein powder cookie dough runny. Plant-based protein powder is made from peas, brown rice and other plants that absorb liquids like crazy. Please do not substitute as cookies will not work.

What oatmeal is the best?

You can use quick oats, rolled oats, old fashioned rolled oats. Please do not use steel cut oats.

What peanut butter to use?

I always buy organic unsalted peanut butter. It is cheap. No hydrogenated oils. Unfortunately peanuts are heavily sprayed with pesticides. You can use any for this time but please buy good for you peanut butter next time. I recommend organic or at least natural peanut butter without additives. Ingredients should be peanuts and maximum a bit of salt.

3. Make Protein Powder Cookie Dough

  • Stir well with a fork to combine.
  • Dough consistency should be runny.
  • Riper the bananas, more liquidy the batter.
  • Add chocolate chips and give a few more stirs.

4. Bake Cookies

  • Spoon mixture onto prepared baking sheet.
  • Cookies don’t spread, so shape them now.
  • Bake for 12 minutes if you have 12 small cookies.
  • Bake for 14 minutes if you got 10 large cookies.

5. Enjoy

  • Cool on a cooling rack for 5 minutes.
  • Enjoy your cookies guilt-free!

Can I Freeze Protein Cookies?

Absolutely. If I have going bad bananas I use them all. I make these cookies or healthy banana muffins or healthy banana bread. Nothing goes to waste in this house.

Freeze cookies for up to 3 months in an airtight container.

  1. I made these with Bowmar Vegan Banana Nut Bread powder, walnut butter, and chopped walnuts. These cookies are easy, delicious, and good for you. Thank you so much!

  2. Hi.. already make twice from ur recipe. So simple and yet healthy.. thanks a lot for ur recipe..
    Quick question = 1cup of oatmeal is how many in gram?
    Cause twice making this, but the final result still wet, i’m kindda hard to put it in tray, and doesnt look nice like yours..

  3. Awesome cookies! I made it with the chocolate protein and doubled up the recipe for 24 cookies!
    My whole family loves it

      1. I didn’t have all the right ingredients so I had to totally wing it, I just couldn’t wait to try. I used these instructions as a foundation, which was very helpful, so thanks! I used Vanilla Whey protein powder, which has sweeteners in, I believe, porridge oats and Cocoa dark chocolate. I managed 12 cookies at 99 calories! 🙂 Delicious although a little chewy?

  4. Just made this Olena and I can’t thank you enough. Your recipe had it all and the cookies turn out so yummy. I followed the recipe down to the letter (Very easy and practical) and will be sharing these cookies with my neigbors here in Sinaloa, Mexico. I thought I had high nutrtional standards until I read your page. Thanks again and look forward to using more of your recipes.

  5. These were so good! I added two tbsp of cocoa powder to make it even more chocolaty. Next time I’m going to add walnuts. The texture is more like a brownie cookie. Guilt-free, sweet-tooth fix. ? Thanks!

  6. I just made these and they turned out better than I expected! I used Isopure unflavoured whey protein powder (just for reference); a nut butter I make myself with pecans, peanuts, almonds, and sunflower seeds; and added in cinnamon and spice clove to give it more of a “banana bread” kind-of feel. As per another comment Olena left, I used raisins instead of chocolate chips. They came out really nicely. The texture is almost bready, which is interesting, but definitely soft. I find the flavour was definitely from the spices and banana, but I was surprised the whey protein didn’t come through – which I am happy about. I should have added nuts, but I completely forgot when making the mixture. I think the crunch would have made them better. Final note – I love that this doesn’t require a food processor, but rather just a fork, a spoon, a bowl, and some force. Thank you!

      1. So I tried this with Pumpkin instead of Banana. (Because it’s cheaper, already mashed, and way less sugar and carbs.)
        Then I used Chocolate flavored whey vs unflavored.

        It was gross!
        I think it’s the lack of banana, which is very flavorful compared to pumpkin.
        And the chocolate flavor whey. I don’t think unflavored would be much better though huh? Do you think? idk..

  7. Hey I can’t eat whey but I made these with beef gelatin protein and it’s a great gluten free dairy free protein alternative (not vegan sadly) which also helps to get the cookie together! Worked really well for me. Love the recipe XXX thanks again

  8. was a little flavorless but i added more bananas and it tasted amazing! super fast prep time and everyone loved them!

  9. Hi. Some questions
    1. Can I pack these cookies in sealed bags?
    2. How long can they be stored?
    3. Is there another ingredient that I can use as a banana substitute? (I don’t like bananas hahah)
    4. Does it work if I use oatmeal?

    Thank you!!

  10. How did you come up with 6g of protein per cookie?

    If you put 2 scoops or 48g of whey protein in one batch of cookies, and each batch makes 12 cookies, wouldn’t it be 2 grams of protein per cookie?

    Let me know if I’m wrong, or if I miscalculated.

  11. I use this recipe when I’m craving something sweet. They always come out great and I experiment with lots of different mix-ins and so far every batch has been successful!

    1. You can thin it out with anything until picture like consistency. It should be runny though. What protein powder did you use? Whey or plant-based by mistake? Only reason it wouldn’t be runny. Or not ripe bananas…

  12. I’ve made this twice with plant based chocolate protein powder. Tastes great & super easy. I got 15 cookies with large bananas. Might add walnuts next time

  13. Delicious cookies, that easy to make. Thanks Olena for the recipe, im from Ukraine too(Odessa), next time i try to add some chocolate and raisins, have a nice day!

    1. You are welcome, Sasha!:) Yup, when I’m out of chocolate chips I add pecans and raisins. Which works only for one of my kids but it’s not my problem.:)

  14. This has become one of my favourites. I add a bit of unsweetened coconut, and a couple pinches of sea salt to counter the bitterness from the stevia in the protein powder I use. Next, I will try using tahini and chocolate protein powder for a chocolate halvah taste

  15. These cookies are so quick to make and are really good. I like that you don’t add sugar, the bananas add the sweetness and the chocolate chips. I substituted tahini for peanut butter and they were awesome. Kept them in frig for quick high protein snack. Thanks!

      1. I just made them (without the baking powder) and they are amazing! I substituted with PB2 powder and no chocolate for less calories. AMAZING!

  16. How would you recommend changing the recipe around for more protein? Like if I double the protein would I just lessen the oats?

  17. I made these cookies today and they tasted so good! However, I was wondering if you could recommend a way to make the cookies slightly less dense and softer in the middle. We made 9 cookies and they were relatively thick so this could be why they were so dense. Thank you!

    1. I don’t think it’s possible just because of oats and no white flour with rising agents etc. I mean these are cookies but definitely without many qualities of real cookies. Make them smaller and maybe try adding some baking soda. 🙂

  18. I just came across your recipe. I’m looking forward to trying it. My thought is to use Coach’s Oats, a Costco favorite of ours. Thanks for the recipe! Ttyl 🙂 Walter

  19. Hey there! When you scooped the batter onto the baking sheet, did you press/flatten them or leave them as is? Or should the batter be loose enough that they spread on their own when spooned? Just want to make sure I get the consistency correct before i bake! 🙂

  20. Awesome recipe! I loved it mostly because how quick it is. I used vanilla isopure protein and PB2 and they turned out great. I will likely do a little less protein powder next time and a slightly shorter cooking time because they were just a touch dry. I also want to add some shredded coconut or maybe some nuts next time 🙂

  21. Hi Olena, what a wonderful website you have 🙂 I dont know how you got it to be low calorie??? when i put the ingredients into my fitness pal the calories tell me its about 140 calories per biscuit 🙁

    1. Hi Stefanie. Thank you! You know, sometimes people enter wrong nutritional info for some ingredients so that could be why. I always check labels of my ingredients and other people’s already entered.

    2. Hey Stefanie, PB2 is a great way to cut calories from the cookies since peanut butter is a large contributor. I followed the recipe exactly with Isopure Vanilla protein powder and two tablespoons of PB2 (mixed with water per instructions) and mine were less than 80 calories per cookie.

  22. Just made these i used pumpkin spice protein powder added a tablespoon of pumpkin pie spice 2 tablespoons of coconuts and I grounded some walnuts and sprinkle them on top it was delicious i would share the photo but it wont let me

  23. Great recipe, I added a few other ingredients, almond flakes, pumpkin and sunflower seeds, I also added some mini marshmallows my clients love them. thank you .

  24. I made these for my boyfriend who’s into working out and having his daily dose of protein, and he absolutely loved these cookies! He was super shocked when i told him there was 6g of protein in EACH cookie. thanks so much for the recipe 🙂

  25. These cookies are amazing!!!! I used PC Soy Isolate Protein Powder (unflavoured) as my Whey Protein is chocolate flavoured and these taste absolutely fantastic. Thanks so much for this and all of your amazing recipes.

    1. Really, they worked with soy protein? I tried to follow the recipe with plant-based protein powder and it didn’t work. I ended up adding way more liquid. But I know with whey they are amazing. Glad you liked them!

  26. Hi just looking for a good protein cookie for my teenage son who wants to get in shape.He has a severe peanut butter/nut allergie and all the reciepies call for peanut butter any ideas.Thanks

  27. We just made them and I absolutely loved these cookies! Great recipe. Just a question, as I might not always have protein powder on me, is there anything that could substitute for it?

    1. Glad you liked the cookies. To answer your question, you probably could replace protein powder with almond flour (ground almonds) or hemp hearts but cookies won’t come out the same. Still good but different texture.

  28. Hi I have read somewhere that whey protein gets destroyed on heating and I just wanted to check if the protein value is accurate and also if 6gm is per cookie or for the entire batch of cookies

    1. It’s perfectly fine in terms of taste and baking. Just the cookies will be sweeter and nutritional info will change. 🙂

  29. These sound delicious but unfortunately I HATE bananas! Could I substitute them for anything? Also I was thinking adding flaxseeds to the mix?

  30. I love this recipe, I changed the peanut butter to PB2 and added sunflower seeds, pumpkin seeds and almonds to give some crunch. Thanks for the recipe

  31. Hi Olena ! I have so much weight to lose & am so happy to have found your blog.
    I love your recipes and your right, dieting & no carbs is not the answer. I also have two kids, I want to lose the weight to be around for them, I also want to teach them how to eat healthy. Thank you, Ellen
