Preheat your oven to 425°F (220°C).
In a microwave-safe bowl, combine the shredded mozzarella cheese and cream cheese. Microwave in 30-second intervals, stirring in between, until the cheeses are melted and well combined.
In a separate bowl, whisk together the almond flour, baking powder, and Italian seasoning.
Add the dry ingredients to the melted cheese mixture. Mix well until a dough forms.
Beat the egg in a small bowl and add it to the dough mixture. Stir until the dough is evenly combined.
Place the dough onto a piece of parchment paper. Use your hands to shape the dough into a round pizza crust, approximately ¼-inch thick. You can also make smaller individual-sized crusts.
Transfer the parchment paper with the shaped crust onto a baking sheet or pizza stone.
Bake the crust in the preheated oven for about 10-12 minutes, or until it is lightly golden.
Remove the crust from the oven and let it cool slightly.
Spread the low-carb tomato sauce evenly over the crust, leaving a small border around the edges.
Sprinkle the shredded mozzarella cheese over the sauce.
Add your choice of keto-friendly pizza toppings.
Return the pizza to the oven and bake for an additional 8-10 minutes, or until the cheese is melted and bubbly.
Remove the pizza from the oven and let it cool for a few minutes before serving.
