Preheat oven to 350 degrees F and line a baking sheet with parchment paper.

In a small bowl, mix dough ingredients together. Add 1/2 tsp water or wet your mixing spoon 3-4 times until you can form a ball of dough with your hands. This may take a few minutes and some elbow grease. Use a rolling pin or the backside of a spatula to form a 10" circle on the baking sheet with the finished dough. (It may help to spray your rolling pin with nonstick cooking spray.)

Mix the chocolate filling (same as the ultimate protein frosting recipe) and line the outer rim of your pizza dough with the filling. Roll the edges, fully enclosing the chocolate filling.

Mix together the butter, apple sauce, protein powder, and cake mix in a small bowl, adding Sprite Zero or diet soda at the end. (If you're not too concerned with fat/calorie content, use 2 Tbsp light butter and omit apple sauce.)This should form a very thick but spreadable "batter" to add to the top of your dough. (Don't cover the rolled portion - or crust - of the dough.)

Add chocolate chips to the top and bake for 10-12 minutes on the center rack.
