Add Mozzarella & Cream cheese to a microwave safe bowl. Heat in 30 second intervals and mix during each pause until they completely combine. Do not scald.
Stir in the egg.
Mix dry ingredients in a small bowl so that they are combined. Slowly add the dry ingredients to the cheese and egg mixture while stirring. Use oiled hands to knead and get a uniform ball of dough. This can be easier if you lightly oil your hands or use latex gloves.
Roll the dough between two sheets of parchment to get a rectangle approximately 1/4 to 1/2 inches thick.
Shape with your hands if needed to get a rectangle. Or use a knife.
Prepare your cinnamon filling by melting the butter, then stirring in the sweetener and cinnamon.
Spread the cinnamon paste over the flattened rectangle.
Roll it up and slice into 12 even sized pieces.
Now you have 12 rolls which you place on a oiled non-stick baking sheet or in a pie dish.
Bake for about 20 minutes.
While the rolls are baking prepare the frosting: Mix cream cheese, yogurt and erythritol.
Spread over the warm rolls and serve. Be careful here. The rolls are delicate when they are hot. You'll want to let them cool a bit before handling or they might (definitely) fall apart.
