Preheat the oven to 425°F (220°C). Line a baking sheet with parchment paper.
In a microwave-safe bowl, combine the shredded mozzarella cheese and cream cheese. Microwave on high for 45 seconds, then stir. Microwave for another 30 seconds until the mixture is melted and smooth.
In a separate bowl, mix the almond flour, baking powder, garlic powder, dried oregano, and salt.
Add the egg to the dry ingredients and mix well.
Pour the melted cheese mixture into the almond flour mixture. Stir quickly to combine into a dough. If the dough is too sticky, let it cool for a minute.
Place the dough on the prepared baking sheet. Using wet hands, press and shape the dough into a 10-inch round crust about 1/4 inch thick.
Bake the crust in the preheated oven for 12 to 15 minutes, or until golden brown and firm.
Remove the crust from the oven. Add your favorite keto-friendly pizza toppings and bake for an additional 5 to 7 minutes until toppings are cooked and cheese is melted.
Let the pizza cool for a few minutes before slicing and serving.
