1. Set oven to 400F (200C).
2. Make dough with flour and Greek yogurt. It will be crumbly initially, but simply knead with your hands until a dough forms.
3. Roll out the dough and spread the filling (applesauce, granulated sugar substitute, cinnamon) evenly.
4. Roll up the dough and place it in the oven for about 13 minutes.
5. While the cinnamon roll bakes, prepare the icing by mixing protein powder, sugar-free/fat-free white chocolate instant pudding mix, and confectioners sugar substitute with milk of choice until desired consistency is reached.
6. Once baked, top with the protein icing and enjoy!
