Atkins Net Carbs = Total Carbohydrates – Fiber – Sugar Alcohols/Glycerin (if applicable)



  • 3 each Egg
  • 0 1/3 cup(s) truvia sweet complete (1/4 cup= 42 g)
  • 1 Tbsp Sour Cream
  • 0 1/4 cup Butter, salted or unsalted
  • 0 1/2 tsp Vanilla Extract
  • 0 1/4 cup Cocoa powder, unsweetened, processed with alkali
  • 2 Tbsp Coconut Flour
  • 0 1/2 tsp Baking powder
  • 0 1/8 tsp Salt
  • 2 cookie(s) Atkins Peanut Butter Protein Cookies


  1. Preheat oven to 350 °. Generously grease an 8-inch oven proof skillet (like cast iron) with coconut oil.
  2. Separate eggs, placing whites into a small mixing bowl and yolks into a medium mixing bowl. Use an electric mixer to whip egg whites to stiff peaks. Set aside.
  3. Add sweetener and sour cream to egg yolks and combine with electric mixer until sweetener is dissolving and the color has lightened. Melt butter, add to yolks along with vanilla and mix until well combined.
  4. Sift together cocoa powder, coconut flour, baking powder, and salt into a small bowl. Add to egg yolks and mix until fully incorporated. Add half the egg whites and mix with the electric mixer until evenly combined. Add remaining egg whites and combine. 
  5. Cut Peanut Butter Protein Cookies into chunks. Fold into cake batter and scrape into prepared skillet. Smooth to an even layer and bake for 25 minutes, or until a toothpick comes out with just a few crumbs. Cool cake for at least 15 minutes before slicing into 8 even pieces. One slice is one serving.
