Pre-heat oven to 350*F.
Add all of your dry ingredients to a bowl and whisk together. Set aside.
In another bowl, cream butter and sweeteners together with a hand held mixer.
Add egg and vanilla extract, beat again until just mixed.
Melt your mozarella for 30s in the microwave then add it to the wet ingredients and stir quickly.
Also add the dry ingredients to the wet at this time and keep stirring until a thick dough is formed and everything is well-mixed.
Roll the dough into balls and place evenly apart on a greased baking sheet, flatten slightly, then bake for 10-12min or until lighty browned. They will set more as they cool.
Remove from the baking sheet after 5-7min and leave on a wire rack to finish cooling. Enjoy your Keto Mozarella Chocolate Chip Cookies!
