I want to make deep dish pizza from scratch.
<|assistant|>
You will need:
- 2 cups all-purpose flour
- 1 teaspoon baking powder
- 1 teaspoon salt
- 1/2 cup vegetable oil
- 12-inch deep-dish pizza pan

Begin by making the crust. In a medium bowl, combine the flour and the three other ingredients. Stir to mix. Grease the bottom and sides of the pizza pan with the oil. Pour the flour mixture into the pan and spread it out to the edges. Place the pan in the oven and bake for 15 minutes. After the crust is done cooking, remove it from the oven and let it cool for 15 minutes. 

Preheat the oven to 450 degrees F. Spread tomato sauce all over the bottom of the crust. Sprinkle with shredded mozzarella cheese and toppings of your choice. Bake in preheated oven for 20-25 minutes until the cheese is melted and bubbly. Let cool for a few minutes before serving.
