Preheat your oven to 375°F (190°C).

In a microwave-safe bowl, combine the mozzarella cheese and cream cheese. Microwave on high for about 30 seconds, stirring until smooth. Repeat if necessary until fully melted.

In a separate bowl, whisk together the almond flour, coconut flour, erythritol, baking powder, cinnamon, and salt.

Once the cheese mixture is smooth, add in the eggs and vanilla extract. Mix well, then gradually fold in the dry mixture until a dough forms.

On a lightly floured surface (using coconut flour), roll out the dough into a rectangle about 1/4 inch thick.

Sprinkle the remaining cinnamon and some erythritol evenly over the dough. Roll it tightly from one end to the other.

Slice the rolled dough into even pieces about 1 inch thick, and place them on a parchment-lined baking sheet.

Bake in the preheated oven for about 12-15 minutes or until they are lightly golden.

Allow them to cool slightly before serving. You can drizzle with a simple mix of cream cheese and your low-carb sweetener for frosting.
