Prepare pans: sprinkle cornmeal in a thin layer in two 12-inch pizza pans. Set aside.
Preheat oven to 425 degrees.
In stand mixer bowl, add 1 cup flour, yeast, cheese, garlic powder, salt and pepper; mix well. Add warm water to flour mixture. Using a paddle attachment, blend on low speed for 30 seconds. Peat on medium speed for 3 minutes.
Switch to dough hook attachment. Gradually stir in enough remaining flour to make a firm dough. Knead until smooth and elastic, about 5 to 7 minutes.
Cover dough; let rest for 30 minutes.
Punch down dough. Divide dough into 2 equal parts. With well-floured or greased fingers, press each half into prepared pans. Top with desired toppings.
Bake for 20 to 25 minutes until edge is crisp and golden brown and cheeses are melted. Serve immediately.
