Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.
Place the shredded mozzarella cheese in a microwave-safe bowl. Microwave on high for 60 to 90 seconds until the cheese is fully melted and soft.
In a separate bowl, mix the almond flour and baking powder.
Add the melted cheese, almond flour mixture, and the egg to a large mixing bowl. Mix with a spoon until combined, then use your hands to knead the dough until it forms a uniform ball.
Place the dough ball between two sheets of parchment paper. Use a rolling pin to roll the dough into a 10- to 12-inch circle, about 1/4 inch thick.
Remove the top layer of parchment paper. Carefully transfer the dough (still on the bottom parchment) to the prepared baking sheet.
Bake the crust for 8 to 10 minutes until it starts to turn light golden brown.
Remove the crust from the oven. Add your desired low-carb toppings.
Return the pizza to the oven and bake for another 5 to 8 minutes, or until the cheese topping is melted and bubbly.
Notes
For an extra crispy low carb pizza, poke the dough several times with a fork before the initial bake.
If the dough is too sticky to handle, chill it in the refrigerator for 10 minutes before rolling.
This recipe makes a grain-free pizza base that holds up well to heavy toppings.
