When it comes to high protein snacks and desserts, I love peanut butter protein bars, chocolate protein bars, and these protein powder cookies

This protein cookies recipe was inspired by Quest protein cookies I saw at the grocery store. They were made with whey protein and had no sugar, barely any carbs, and claimed to taste like birthday cake.

Well, being the skeptic I am, I decided to try them out and was NOT impressed that it also came with a $5 pay tag. Unfortunately, I was at the checkout and hungry, so went through with buying it.

While the protein cookie was initially delicious, it also left a lingering artificial sweetener taste. 

Birthday Cake Protein Cookies

My homemade protein cookies taste like birthday cake and need just 4 ingredients. Unlike the store bought ones, you can actually pronounce them. In fact, you probably have them in your cupboard right now. 

Taste wise, they are a mix between my peanut butter cookies and almond butter cookies, but less nutty and more protein. They have a slight vanilla flavor, with some sprinkles added in for fun. The texture though is JUST like any decadent and bakery style cookie- soft, thick and chewy.

How to make protein cookies

The Ingredients 

  • Peanut Butter– Smooth and drippy peanut butter, with no added sugar. Avoid using crunchy peanut butter, as you’ll find the mixture harder to mix together. If you’d like to use another nut or seed butter, feel free to do so, like almond butter or sunflower seed butter. 
  • Granulated Sweetener– Any granulated sweetener will work. I’ve tried it with monk fruit sweetener, erythritol, and also coconut palm sugar. 
  • Protein Powder– A must for any good protein cookie recipe! Use vanilla protein powder, to give the birthday cake flavor!
  • Egg OR ground chia seed– Room temperature eggs OR, if you’d like to keep it vegan, use ground chia seed.
  • Sprinkles– optional, but adds a fun touch! 

The Instructions

Start by mixing together all your ingredients, except for your sprinkles. Form 12 balls of cookie dough and cover in sprinkles, before placing onto a cookie sheet or baking sheet. Gently press on each ball and bake for 12-14 minutes, or until the edges are beginning to brown. Remove from the oven and let cool on the baking sheet completely.

Which protein powder is best for baking? 

Not every protein powder is created the same. Some are thicker than others, some are finer than others and some have different additives in it. As a general rule of thumb, all protein powders can work, but they will leave different textures. Here are the more mainstream protein powders and what texture and flavor profiles they have.

  • Brown Rice Protein Powder– Earthy in flavor and texture, this vegan protein powder keeps the cookies soft and chewy. Be sure to use a vanilla flavored one, otherwise, the cookies will be very bland. 
  • Casein Protein Powder– My favorite protein powder for baking. Casein protein powder never dries out baked goods, and has the most delicious flavor. Casein is only suitable for gluten free and keto diets. 
  • Whey Protein Powder– My least favorite protein powder to use, whey is the most natural protein powder, and also the lowest in carbs. However, they are most prone to dry out baked goods, so be sure to keep an eye on it. Whey is great if you want super low carb cookies, or if you follow a keto or paleo diet. 

Tips for making the BEST high protein cookies

  • You MUST enjoy the taste of the protein powder you use. Trust me, many brands out there can have quite the overpowering flavor, and it is not always pleasant. 
  • Do not overbake the cookies, as they continue to cook as they cool down. While the cookies may look a little underbaked, they will firm up beautifully while cooling down. 
  • Peanut Butter can also be overpowering, so if you don’t want peanut butter protein cookies, you can replace this with smooth almond butter. 
  • If you make whey protein cookies, keep a careful eye on the cookies around the 10 minute mark- They can dry out very quickly. 
  • If you opt to make the cookies with the ground chia seed instead of an egg, start with 3 tablespoons. If the cookies aren’t thick enough, add an extra tablespoon of ground chia seed. 
  • For protein chocolate chip cookies, add 1/4 cup chocolate chips.

Storing and Freezing Tips

  • To store: Leftover protein cookies can be stored at room temperature, in a sealed container, for up to 14 days (2 weeks). If you’d like them to keep longer, store them in the refrigerator. 
  • To freeze: Freeze leftover cookies by storing them in a ziplock bag. They will freeze well for up to 6 months.

    1. So funny- I have never really thought of what flavor birthday cake is- it’s just…birthday cake flavored!! I love this recipe though and I’m bookmarking it to try! Thanks for the link up and Happy Wednesday!

    2. Is it normal that my “reintroduction” of trying to eat wheat again has come solely in the form of Lenny & Larry’s cookies? Our booth was next to them at the Fancy Food show and needless to say 3 days of cookie samples was irresistible =l

      Which one is your fave!? I thought it would be birthday cake HANDS DOWN but i have to say snickerdoodle might have taken the (cake?..) for me. although I am sure your FULL SIZED ONE SERVING cookie is going to take all of my cakes, snickers and doodles and allow me to remain cookie full and gluten free 😉

      P.S. expo west.. what’s happening!?!?

    3. You are a SAINT! As someone who is obsessed with Lenny & Larrys cookies I can only scream thank you for these!! Making this giant cookie of bliss asap. Gimme more flavors!! 😉

    4. Oh, wow, thank you for shedding the light on ‘Lenny’s and Larry’s.’ I’ve been wondering what they are. They are all over Instagram. They have a great PR campaign. This looks just as tasty!

    5. I remember when we went to Farm Boy and you helped me decide to buy the GIANT Lenny & Larry’s white chocolate macadamia cookie along with the snickerdoodle one! The macros are absolutely AMAZING for your cookies!! Birthday cake has always been cake batter for me! 🙂 tastes awesome!

    6. There’s that cashew butter!! 🙂 Ugh I want this cookie right now. Birthday cake tastes like extra delicious vanilla cake with sprinkles. But if you think about it, shouldn’t birthday cake flavor be subject to your own preference? So like, I want carrot cake on my birthday. Birthday cake should taste like carrot cake to me.
      I’m being obnoxious k bye.

    7. You’re such a liar! Not because of the sprinkles…. 😛
      And I am with Alison. Birthday cake should taste like carrot cake. No competition.

    8. Omg yes. so ready for these.

      Question – which protein powder did you use in the picture? I know often you say which is pictured but I can’t find that in the text!

      1. YES! Can’t wait to share each flavor over the next week! 🙂

        The pictured one was a vegan blend but I’m going to test out a new brand today because I want to see if I can get a better texture which can last for a week- I’ll let you know!
