01 - Preheat oven to 425°F. Line a baking sheet with parchment paper.
02 - Combine shredded mozzarella and cream cheese in a microwave-safe bowl. Microwave for 1 to 2 minutes, stirring halfway through, until the mixture is smooth and fully melted.
03 - Add almond flour, baking powder, salt, and egg to the melted cheese mixture. Mix thoroughly until a smooth, uniform dough forms.
04 - Transfer dough to the prepared baking sheet. With oiled hands or a spatula, flatten the dough into a 12-inch round about 1/4-inch thick.
05 - Bake crust in the oven for 10 to 12 minutes, or until it is golden and the edges begin to crisp.
06 - Remove crust from oven. Spread tomato sauce evenly over the surface, then top with shredded mozzarella, pepperoni, olives, and bell peppers, or alternative keto toppings as desired.
07 - Return to oven and bake for 7 to 8 minutes, or until cheese is fully melted and bubbling.
08 - Remove pizza from oven, sprinkle with dried oregano or Italian herbs, slice, and serve hot.
