I finally got time to make over these protein cookies and post new pictures. Last week we announced Protein Snack March and I ordered organic grass-fed whey protein powder first time in my life. I usually buy plant-based Orgain at Costco but for making tasty protein cookies you need whey protein powder. When I see a comment like “this was a huge fail” on any protein powder recipe, 99% of times correct protein powder wasn’t used. That’s all you have to remember when baking with protein – use the type of powder that recipe calls for.
This is super easy and quick whey protein cookie recipe that is naturally sweetened with bananas. Therefore, don’t expect chewy crunchy cookie. It’s more of a moist, sweet with melted chocolate chips treat. We really-really like these low carb protein cookies including the kids because unlike plant-based protein, whey is tasteless.
MY LATEST RECIPESThis recipe makes great pre- and post-workout, and a late night couch snack without the guilt. Any time you’ve got brown bananas, whip up as many batches of cookies as you have bananas to use, and freeze for later. I can guarantee you have all ingredients on hand to bake these cookies right now. That easy!
How to Make Protein Cookies
Ingredients
Bananas: Brown, yellow with brown spots, thawed – all are OK. Ripe the bananas, more liquidy the batter. It’s fine.
Peanut Butter: I recommend organic or at least natural peanut butter without additives. Ingredients should be peanuts and maximum a bit of salt.
Oats: Rolled old fashioned or quick cooking oats work.
Protein Powder: It’s gotta be whey! I recommend the one with minimum ingredients, at least grass-fed, preferably organic. Like 17 Whey. Any unsweetened or vanilla whey protein powder will work though.
Mash bananas with a fork. Add whey protein powder, oats and peanut butter.
Stir well to combine (batter’s consistency will be runny). Add chocolate chips and give a few more stirs.
Spoon mixture onto prepared baking sheet (cookies don’t spread, so shape them now). Bake for 12 minutes (if you got 12 smaller cookies) and 14 minutes (if you got 10 larger cookies). Cool on a cooling rack for 5 minutes.
Enjoy your cookies guilt-free!

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
★★★★★
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!
★★★★★
Could I add baking powder to make them fluffier?
You can try a bit but I’m not sure that will work though. I tried with my protein pancakes and they didn’t taste good, and no fluff. These protein cookies are quite soft.
I just made them (without the baking powder) and they are amazing! I substituted with PB2 powder and no chocolate for less calories. AMAZING!
These protein cookies were very good.
★★★★★
How would you recommend changing the recipe around for more protein? Like if I double the protein would I just lessen the oats?
To do that, I would have to retest the recipe as adding extra protein change ingredients ratio and taste.
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!
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. 🙂
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
Hi Walter. Yes, you can use Coach’s oats. Cookie’s texture might be more coarse but it’s OK. Enjoy!
would there be any changes for high altitude?
No. These are not traditional flour cookies.
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! 🙂
Just left them as is. You drop the batter, it is not thick you use ripe bananas.
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 🙂
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 🙁
How many grams of each of the ingredients are in a cookie?
No idea, honestly. Just enjoy it! It’s already healthy!
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.
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.
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
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 .
Great! Using my recipe for clients is an honour.:)
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 🙂
You are welcome, Sum!:)
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.
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!
I too love these cookies. We use unsalted Almond Butter and they are awesome.
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
Yes. You could replace peanut butter with coconut oil or any other fat.
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?
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.
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
6 gm is per cookie. Here is what I found: “Baking whey protein powder may denature its proteins, a process that changes the physical or chemical structure of the protein. Denaturation does not mean not nutritious. It simply means changed, and the change may be temporary or minimal.”

How long will these cookies stay good if not refrigerated? My husband was wondering if they could be shipped.
Hi Laura. I would say in an airtight container, for up to a week, 10 days…
Hi. I plan to use sweetend and flavored protein powder with salted peanut butter. That is what I have. Your thoughts?
It’s perfectly fine in terms of taste and baking. Just the cookies will be sweeter and nutritional info will change. 🙂
These sound delicious but unfortunately I HATE bananas! Could I substitute them for anything? Also I was thinking adding flaxseeds to the mix?
You can definitely add flax seeds but unfortunately bananas is what makes these cookies.
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
Hi Olena ! I have so much weight to lose & am so happy to have found your blog.

Hi Ellen. I’m so glad to hear that. Yes, you should do it for yourself and your family. And to be healthy is actually pretty easy and the best feeling in the world. So, go for it!
