Healthy Peanut Butter Cake with Chocolate Frosting

Servings: 2 6" cake layers
Prep Time: 30 mins
Cook Time: 50 mins
Total Time: 1 hr 30 mins



  • 430g (1¾ cups) Unsweetened Applesauce
  • 275g (1 cup + 2 tbs) Egg Whites (fresh, not cartoned)
  • 128g (½ cup) Natural Peanut Butter
  • cup  Unsweetened Vanilla Almond Milk
  • 48g (¼ cup) Sucanat
  • 48g (¼ cup) Granulated Erythritol (or more sucanat)
  • 1 tsp Liquid Stevia Extract
  • 180g (1½ cups) Oat Flour
  • 150g (1¼ cups) Peanut Flour
  • 1 tbs Double-Acting Baking Powder
  • ½ tsp Salt



For the Cake:

  • Preheat the oven to 350 degrees Fahrenheit and generously spray two 6" cake pans with cooking spray.
  • In a large mixing bowl, whisk together the applesauce, egg whites, peanut butter, sucanat, erythritol, almond milk, and stevia extract.
  • In a medium-sized mixing bowl, whisk together the oat flour, peanut flour, and baking powder.
  • Sift the dry ingredients over the wet and stir together. Whisk the batter vigorously for 10-20 seconds, or until all of the clumps are gone.
  • Pour batter evenly into the prepared pans and bake for ~52 minutes, or until surface is golden brown and springs back when tapped. Remove cakes from oven and let cool in the pans for 5 minutes, then turn them out onto a wire cooling rack.

For the Frosting:

  • In a stand mixer bowl with whisk attachment, add the protein powder and cocoa powder. Whisk on low.
  • Increase mixer speed to medium and slowly drizzle in the almond milk. Add the stevia. Whisk until creamy and fluffy. Frost the cake and refrigerate for ~30 minutes to firm the frosting. Slice and serve!
