In a small microwave safe bowl, heat mozzarella and milk until melted and whisk together.
In a large mixing bowl, add cheese mixture and let cool for 2 minutes. Add in flour, egg, and baking powder to combine. Mix until ball of dough forms.
Form dough into a ball with your hands. Divide into 4 pieces and roughly flatten into circles. Place shaped dough on baking sheet.

Enjoy!
