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
Step One: 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.
Step Two: 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 as well.
Step Three: Mix in the peanut butter, vanilla extract, water, and optional liquid sweetener to form a protein cookie dough.
Step Four: Form into a large ball, or make two smaller balls if you want two chocolate chip protein cookies.
If you prefer a flatter cookie, press the ball into a cookie shape with your hands or a fork, because these will not spread in the oven.
Step Five: Place the unbaked cookie on a baking tray, and bake on the oven’s center rack for seven minutes.
Step Six: 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.

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.

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!).
Kath says
Hello – I would like to know what sweetner you used for the recipe. Thanks so much!
Teenlette says
Love this recipe. It’s a bit tiresome to scale up to make more that 2x recipe. Have you considered a scale up calculator for the recipes like some other recipe apps?
Laura Stevenson says
I haven’t made this yet but I’m wondering what are some sweetner options besides regular granulated sugar.
Mary says
Delicious protein cookie! I tried a couple of recipes before this one and this is the best for me. I added a half tablespoon each of chocolate chips and peanuts. I used maple syrup as my sweetener and naked vanilla protein powder.
Lisa says
My teenage son is a cancer survivor who has struggled to gain weight after a brutal treatment. I have tried every protein powder, bar, shake, drink, recipe ect and this one FINALLY is a huge hit. I can’t thank you enough! (I used Ascent 100% whey unflavored protein powder)
CCK Media Team says
Thinking of him, and of your entire family. We are so incredibly glad the recipes can help, even if in a small way!
Rose says
These are TOO GOOD! So much cheaper than store-bought and no unhealthy ingredients! This is exactly what I was looking for, thank you <3
