This single serving protein cookie recipe is packed with over 25 grams of protein!
Protein cookie for one
This thick and chewy protein cookie recipe is a game changer.
I can almost guarantee that the first time you make it will not be the last.
In just the past month, I’ve made the recipe at least ten times, and I’ve completely stopped buying protein cookies at the grocery store.
With a deliciously rich flavor and pillow soft texture, it’s almost impossible to believe the stellar nutrition facts on this secretly healthy dessert!

High protein cookie ingredients
To make the single serving cookie, you will need peanut butter, protein powder, sweetener of choice, salt, baking soda, water, and pure vanilla extract.
Almond butter, cashew butter, low carb macadamia nut butter, or sunflower butter (for a nut free protein cookie) can all be substituted for the peanut butter.
I recommend unsweetened protein powder, because it doesn’t have that common artificial aftertaste found in so many flavored protein powders.
For the cookie in the photos, I used Plant Based Pea Protein Powder.
If you have a protein powder flavor that you like, feel free to use it here and adjust the added sweetener if needed.
The homemade protein cookie can be egg free, dairy free, sugar free, vegan, keto friendly, and gluten free.
For cookies without protein powder, try these Keto Peanut Butter Cookies.
Five cookie flavor ideas
Oatmeal Raisin: Add up to a tablespoon of raisins to the batter, along with a fourth teaspoon of ground cinnamon.
Nutella Cookie: Replace the peanut butter with Homemade Nutella or any chocolate hazelnut spread. Stir in a small handful of finely chopped hazelnuts.
Birthday Cake Protein Cookie: Use cake batter protein powder and cashew butter, regular butter, or macadamia nut butter. I also added rainbow chips, above.
White Chocolate: Add white chocolate chips to the dry ingredients, or press a few into the unbaked cookie before it goes in the oven. You can also add macadamia nuts.
Snickerdoodle Protein Cookie: Use almond butter or cashew butter instead of peanut butter. Add a fourth teaspoon of ground cinnamon with the dry ingredients, or roll the cookie dough ball in cinnamon sugar.
How to make a single serving protein cookie
Preheat your oven or toaster oven to 350 degrees Fahrenheit.
If your peanut butter is not already soft, let it sit out of the refrigerator for a few hours or gently warm it until easily stir-able.
Stir the protein powder, baking soda, salt, and optional granulated sweetener together in a cereal bowl. If adding chocolate chips, you can stir them in now too.
Mix in the peanut butter, vanilla extract, water, and optional liquid sweetener to form a protein cookie dough.
Form into a large ball, or make two smaller balls if you want two protein cookies.
If you want a flatter cookie, press the ball into a cookie shape with your hands or a fork, because these will not spread in the oven.
Place the unbaked cookie on a baking tray, and bake on the oven’s center rack for seven minutes.
Let the cookie sheet cool on the counter before removing the cookie. It will firm up considerably as it cools.
While a few readers have had success using a microwave, I have not personally tried it for this recipe.

The recipe was adapted from my Vegan Peanut Butter Cookies and Protein Cookies.
Single Serving Protein Cookie
Ingredients
- 3 tbsp protein powder (16g)
- 2 tbsp peanut butter (30g)
- 1 1/2 tbsp sweetener of choice
- 1 tbsp water
- 1/4 tsp pure vanilla extract
- 1/16 tsp each: baking soda and salt

Donna M Lord says
Just a question, most peanut butter I’ve used had only had 8 gms of protein, how is your recipe 30gms? Thank you. I will still try your recipe 😊
CCK Media Team says
Hi Donna, the rest of the protein comes from the protein powder.
Matt says
Hello. Not sure if this was actually answered but the 30g refers to the weight of the peanut butter and not the grams of protein.
teri says
Have not made these yet — not a big fan of peanut butter — is there a substitute or is it ok to leave it out?
CCK Media Team says
Hi, yes there are many substitution options! If you look under the “ingredients” heading in the commentary section, it lists a bunch of peanut butter free options 🙂
Amanda says
Hey there! I know vegan protein powder affects baking differently and sometimes doesn’t turn out as great. Sorry if I missed it, but have you tried it with that? I can’t use whey protein powder because I’m lactose intolerant
CCK Media Team says
Hi, yes Katie mentions in the commentary using pea protein powder. She has a link in the post to the brand she uses.
Heather says
Can PBFit be used instead of peanut butter?
CCK Media Team says
Sorry we have never used that. Be sure to report back if you experiment!
Alison says
I’m curious about this as well! Please let us know if you try it with success!
Linda Day says
Oatmeal Raisin sounds great; one question: it says:
Add up to a tablespoon of raisins to the batter, along with a fourth teaspoon of ground cinnamon.
Without oatmeal?
CCK Media Team says
Hi thank you for catching that! It seems we forgot the recipe doesn’t have any flour (even oat flour). Katie has made the recipe with half protein powder, half oat flour with success before. Or you could throw in a very small sprinkle of rolled or quick oats before forming into a ball, and that add some nice texture too.
Kayla says
This was delicious! So much better than lenny and larrys.
Elsa says
Hi Katie and team,
I’m curious what sweetener you used for the nutrition label. Does artificial sweetener work well here?
nan says
For the sweetner, can you use honey or maple syrup?
Joanna says
I used maple syrup and it was great
Dee says
I would love to try this recipe.. any chance that it can be cooked in the air fryer?
CCK Media Team says
It sounds like a fun experiment but we have never tried!
Erin says
What peanut butter do you use to get 12g of fat.
All mine for 2 tbls have 16g.
Morgan says
This was the perfect snack to increase my protein intake for the day! It was quick and easy to make, and it tasted delicious 😋 Next time, I plan to leave it in the oven a little longer because my center didn’t set as well as the edges, and I’m going to use less sweetener because my protein powder already has coconut sugar in it. I would highly recommend this treat to anyone looking for a protein rich dessert!
Beth says
Just tried…it was okay. Very much tasted like protein powder; I’m sure the brand used makes a difference. I’m wondering if it might be better with less protein powder and then throw in an egg instead (I know that’s not for vegans out there).
CCK Media Team says
Results of recipes that have protein powder will definitely depend on the type of protein powder used – there are so many options, so if you do not like one, try others to see how the results differ. Edible experiments are the best kind 🙂
Tiffany Glenn says
Best protein cookie I’ve ever made! So many I’ve tried are just nasty. This one is on point!
CCK Media Team says
Thank you so much for making it!
Melissa says
This was so delicious! A great way to please the sweet tooth without going over my Macros!
Deanna Arnold says
SO good! What a nice cookie treat!
Erika says
Any tips on how to measure 1/16 tsp of baking soda…?
NF says
Maybe 2-1/8th tsp. IDK.
CCK Media Team says
You can either fill up half of the 1/8 tsp measuring spoon or they sell small measuring spoons for pretty cheap on amazon, a great option for those who make a lot of single serving desserts: https://amzn.to/49uri9r

Sarah Goode says
My favorite protein cookies I’ve tried so far. Thank you for this recipe!
Alicia says
How many calories are in this recipe? Thanks!
CCK Media Team says
Hi, there is a link to full nutrition facts at the bottom of the recipe box 🙂
Michele Palafox says
Would collagen work to replace protein powder?
Gaby says
1/16 of a teaspoon? Don’t get it. How much is that. A tiny pinch?
Kay says
Half of an 1/8 of a teaspoon.
Kat - the other 1 says
Occasionally you can find a three set of oddly named measuring spoons, Pinch, Dash, & Smidgen. If I remember correctly, the biggest is equal to 1/4tsp, next down is 1/8tsp, and smallest is 1/16tsp. Usually in stainless steel. Come in quite handy at all the odd times! 😁
Kat - the other 1 says
Or the largest was 1/8tsp, then 1/16, then 1/32tsp. One of those! Either way you get the 1/16tsp! Lol
Shlomit says
My boyfriend says these are the best cookies he’s ever had LOL and I don’t disagree
Jamie Baumgardner says
I have tried many single serve cakes and cookies, but this is by far the best!! I only used 1tbsp of stevia, and 1 tbsp pb2 and 1 peanut butter, it came out amazing, probably needed 8 minutes instead of 7 but it was still amazing, love me a good cookie! 🍪
Bh says
Great!
Bh says
Amazing! I’ve eaten it almost daily for weeks lol. I use coconut sugar. I would *not* recommend the microwave. The oven keeps it moist
Lisa says
Worth making, but be selective about the protein powder you use. This goes without saying, but if you don’t like the taste of your protein powder, then you won’t like the taste of this cookie (or cookie dough!).
