1. In a microwave-safe bowl, combine the mozzarella cheese and cream cheese. Melt them together in 30-second increments, stirring each time until smooth.
2. Add the almond flour, baking powder, and beaten egg white to the melted cheese mixture. Mix until a dough forms. If the dough is too sticky, add a little more almond flour until it holds together.
3. Roll the dough out flat on a parchment paper surface.
4. In a small bowl, mix the vanilla extract, liquid stevia, and ground cinnamon. Brush this mixture evenly over the rolled-out dough.
5. Carefully roll the dough up into a log and cut it into 6 equal pieces.
6. Place the cinnamon roll pieces in a greased baking dish and bake in a preheated oven at 350°F (175°C) for 35 minutes or until golden brown.
