Sprinkle a clean counter or a large silicone baking mat with almond flour.
In a large saucepan, melt the cheese and butter together over low heat until they are melted and can be stirred together.
Remove from heat and add the almond flour, coconut flour, baking powder, garlic powder, and salt. Add the egg and stir everything together until a cohesive forms. Use a rubber spatula to really knead the dough together in the pan. It may still contain some streaks of cheese.
Turn the dough out onto the prepared work surface and knead until uniform. This will only take a little kneading. If your dough is still very sticky, add a tablespoon or two more almond flour and work it in.
Sweet Mozzarella Dough: Leave out garlic powder and add ¼ cup powdered sweetener and 1 teaspoon vanilla extract along with the almond flour.To make low carb pizza crust:
Roll the dough out between pieces of parchment paper to 12 inches (0r use a silicone mat on the bottom)
Remove the top parchment and roll up the edge a little to create a crust
Transfer the bottom parchment with the dough on it to a cookie sheet or pizza stone
Bake at 350F for 10 to 15 minutes, until starting to brown and firm up.
Remove and top with your favourite toppings and bake again until melted and bubbly.
