Spray your chosen pan with cooking spray.
Place frozen dough on your pan. Lightly spray the top of the cinnamon rolls with nonstick spray and cover with plastic wrap to keep from sticking to dough while rising.
Preheat the oven to 200 F and turn off once heated.
While the oven is preheating, bring 2 quarts to a boil and pour into a pan on the lowest rack in the oven.
Place rolls in the oven and allow them to double in size.
Remove the pan of water and carefully remove the plastic wrap.
With the rolls still in the oven, reheat the oven to 350.
Once heated, bake until golden brown. 15-20 minutes
