01 - Set oven to 450°F (230°C) and place a pizza stone on the middle rack while preheating.
02 - Pulse cauliflower florets in a food processor until finely ground and the texture resembles rice.
03 - Transfer the riced cauliflower to a clean kitchen towel and squeeze thoroughly to remove excess moisture.
04 - In a large mixing bowl, blend the drained cauliflower, eggs, mozzarella, Parmesan, oregano, garlic powder, salt, and black pepper until uniform.

06 - Slide the shaped crust with parchment onto the preheated pizza stone. Bake for 12 to 15 minutes until golden and firm.
07 - Remove the crust from the oven. Evenly spread pizza sauce over the crust, then top with mozzarella, Parmesan, and any desired optional toppings.
08 - Return pizza to oven and bake for an additional 8 to 10 minutes until cheese is melted and bubbly.
09 - Allow to cool 3 to 4 minutes. Garnish with fresh basil, slice, and serve hot.
