  • ½ cup liquid egg whites
  • ½ cup chocolate pea protein powder
  • 2 Tbsp cocoa powder
  • 3 Tbsp xylitol (or your sweetener of choice)
  • ¼ cup rolled oats (gluten-free or regular)
  • ¼ cup almond milk
  • ½ tsp baking powder
  • ¼ cup vanilla (or strawberry) whey protein powder
  • ¾ cup Greek yogurt
  • 1-2 Tbsp strawberry (or vanilla) casein protein powder


  1. Preheat oven to 325°F.
  2. Blend all ingredients for the cake layers together. Spoon four separate “cakes” onto a cookie sheet lined with parchment or silicone.
  3. Bake for about 15 minutes or until a knife inserted into the middle comes out clean. Remove from oven and let cool.
  4. Meanwhile, blend the filling ingredients together. Use more or less protein powder, depending on how thick you want filling.
  5. Slice the cooled cakes horizontally to make room for the filling. (You could also leave them whole for super thick whoopee pies.) Spread the filling thickly between the layers.
