The Ultimate Protein Cookies

by Michael

Finally!  My first recipe here on Fatherhood: Reloaded, and they’re my Ultimate Protein Cookies! I’m going, to be honest, upfront; I hate these websites that will give you a recipe, but you have to scroll down through a dissertation to get to the actual recipe!
I do not plan on doing that here.  The way I see it, if you come here searching for a recipe, you’re looking for the recipe, not my long-winded story about how I came across a mystical notecard with an amazing and undiscovered recipe written in pencil faded handwriting. Not going to happen! (I admit this first recipe maybe a little more heavy-handed than the rest).

My intentions have been to start posting recipes on here for a while.  I have a ton of recipes as my wife and I both love playing in the kitchen!  We’ve previously cooked fairly strict keto and came up with some awesome meals in the past.  We’re now off the keto-train with the baby on the way, and while we don’t eat as strict as we once did, we do keep healthy. (With a few cheats here and there.)

These protein cookies actually started out as a snack back when we were on keto.  The coconut flour, Truvia brown sugar, and sugar-free chocolate chips still call back to those days, and while these aren’t carb heavy cookies, I don’t feel like they’re exactly as keto-friendly as they could be now.  I consider this recipe as a “base recipe”. I’ve not included a nutrition breakdown as there are elements you can change for your own preferences. The most flexible is the choice of whey protein. I started off using Bowmar Nutrition Protein Frosted Cookie, but after the flavor changed, I’ve moved on to others. The texture of the cookies remains fairly consistent despite brand changes. Plus, it’s fun being able to mix the flavors of the cookies up.
Note: the cookies used in the photos are made with Pro Jym Ultra-Premium S’Mores Protein Powder per my wife’s request.

Enough of my rambling, I’ll let the cookies speak for themselves.

The Recipe

The Ultimate Protein Cookie

The best protein cookie, that doesn't taste like a protein cookie
Prep Time 15 mins
Cook Time 10 mins
Course Snack
Servings 12 cookies


  • 1/2 cup Peanut Butter or Nut butter of choice
  • 1/4 cup Truvia Brown Sugar Blend or coconut sugar
  • 1/4 tsp salt
  • 3 large eggs
  • 1/2 tsp pure vanilla extract
  • 1/4 tsp baking soda
  • 1/2 cup whey protein powder
  • 2 tbsp coconut flour
  • 1 scoop collagen peptides
  • 1/3 cup sugar-free chocolate chips


  • Preheat oven to 350ºF, line a baking sheet with parchment paper.
  • In a medium bowl, combine your peanut butter, sugar, salt, eggs, vanilla extract, and baking soda. Stirring until well mixed, with a rubber spatula, start working in the protein powder, collagen, and coconut flour until well combined. Fold in the chocolate chips.
  • The dough should be sticky, but not runny. the texture may vary based on your choice of protein powder. If you need a firmer dough, add a little more protein powder. If the dough seems too firm or dry, add a little milk.
  • Using a cookie scoop or spoon, drop your cookie dough onto your prepared baking sheet. I consistently come out with 12 cookies with this recipe. You can use the bottom of your spoon to flatten the tops of the cookies some or leave them as they are. The cookies will not spread out but will puff up some during baking.
  • Baking for 10 minutes. The center of the cookies will still seem soft but will firm up. Allow the cookies to cool on a baking sheet for 5 minutes before transferring them to a wire rack (or directly to your mouth!)


  • You cannot substitute any other type of flour for the coconut flour.  It needs to be coconut flour.
  • The use of collagen peptides is optional.  If you choose not to include collagen, start off with only 2 eggs, or maintain the 3 eggs and add a scoop of protein on top of your half cup.  I use Vital Proteins Collagen Peptides in my cookies now.  I previously used Bowmar Nutrition Collagen Peptides with the same results.
  • Your choice of peanut butter and protein powder will affect the consistency of your dough. I used natural peanut butter which tends to be smoother/thinner than other nut butter. I use Natural Creamy Jif Peanut Butter 
  • I've only used whey protein with this recipe, so unsure how other proteins will do.  I have used any number of different flavors and brands.  For this batch in the photo, I used ProJym Ultra-Premium Protein Blend S'mores (per wife's request) and have used a number of Bowmar Nutrition and Dymatize flavors. This is the base recipe I've used with all of them, and the cookies have been great.
