Thaw rolls until they are soft, but not risen. Be sure to cover them with greased plastic wrap while they are rising.
Grease a half sheet baking pan with cooking spray.
Pour heavy cream in a half sheet baking pan. The cream should completely cover the bottom of the pan. Add a splash more if needed.
Sprinkle brown sugar over cream. Shake the pan a little and the brown sugar will settle a little bit.
Set the softened cinnamon rolls in the cream. Cover with plastic wrap. Let sit at room temperature until doubled in size and completely risen. It usually takes about two hours.
Bake at 350 degrees for 15-18 minutes.
Cool. Frost with icing packets included in the cinnamon roll package.
Notes
Caramel Rolls are best served fresh. However they can be stored at room temperature for up to two days. Microwave them for a about 10-20 seconds before serving leftover rolls.
