Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.
In a microwave-safe bowl, combine the shredded mozzarella and cream cheese. Microwave for 60 to 90 seconds until the cheese is melted and easily stirred.
Stir the melted cheese mixture until smooth. Add the egg and almond flour to the cheese mixture.
Mix the ingredients until a uniform dough forms. You may need to knead it briefly with your hands.
Place the dough between two sheets of parchment paper. Roll the dough out to about a 1/4-inch thickness into a 10-12 inch circle or rectangle.
Remove the top sheet of parchment paper. Poke the dough all over with a fork to prevent large bubbles.
Bake the crust for 8 to 12 minutes, or until it is lightly golden brown and firm.
Remove the crust from the oven, add your desired toppings, and return to the oven to bake until toppings are hot, about 5 to 8 minutes more.
Notes
For a crispier crust, bake the crust for an extra 3-5 minutes before adding toppings.
If the dough is too sticky to handle, chill it for 10 minutes before rolling.
You can substitute coconut flour for almond flour, but use only 1/2 cup, as coconut flour absorbs more liquid.
