Bake at 425 degrees Fahrenheit by placing 13 hot charcoal in a circle beneath the 16-inch oven and a double ring of charcoal around the lid. Bake until biscuits are golden brown, about 15 to 20 minutes. If you are baking in the 12-inch oven, place 9 hot charcoals in a circle beneath the oven and make a double ring around the lid.
