Protein Birthday Cake Cookies

Protein Birthday Cake Cookies

Remember that yellow box cake mix? I used to grab a spoon and eat the raw batter from the bowl sometimes (always*). These cookies have that same nostalgic flavor we know and love but they’re safe to eat and protein packed!

This recipe was actually a success the first time around. I added a few ingredients into the bowl that I thought would work and then I tried some of the batter (some things never change). The look on my face was probably priceless because I was not expecting it to taste JUST LIKE the real thing. Being a cake batter connoisseur, my new discovery was definitely a highlight.


  • Applesauce- keeps the cookies moist and rich without all of the butter! Helps add sweetness along with fiber, vitamin C, and other nutrients.
  • Monkfruit- acts as a sugar replacement without the calories and spike in blood sugar. You can replace with any granulated sweetener, but it will affect nutritional value unless it’s a zero calorie alternative.
  • Eggs- help create structure in the cookies and the yolks add to the cake batter taste. Can replace with just egg whites or flax egg but won’t achieve same results.
  • Vanilla extract- adds flavor; not necessary, but it is a birthday cake staple!
  • Coconut flour- probably my favorite flour! It has a high protein and fiber content, and is super absorbent, meaning you need less of it (this ingredient is very difficult to substitute).
  • Tapioca flour- gives the cookies a chewy texture and helps hold them together (can sub cornstarch, cassava flour, or arrowroot).
  • Baking soda- leavening agent that helps the cookies rise.
  • Salt- brings out the flavor and helps balance out the sweet.
  • Protein powder- the star of the show in this recipe! I used the Pescience cake pop protein powder. The whey/casein blend is ideal for baking since casein helps thicken the cookie and give it a better texture. You can replace with another protein but the birthday cake flavor won’t be prominent and the texture won’t be the same.
  • Sprinkles- optional, but adds color and completes the birthday cake vibe.
