The night before, arrange frozen cinnamon rolls in a 3.5 quart casserole slow cooker. Cover the slow cooker insert with aluminium foil or plastic wrap and place in the refrigerator to allow the frozen cinnamon rolls to thaw.
In the morning remove the cinnamon rolls from the refrigerator and set them on the counter to allow the rolls to rise for about 1 to 2 hours.
Pour melted butter over the top of the cinnamon rolls in the slow cooker.
Sprinkle the powder pudding mix over the rolls evenly.
Cover and cook on HIGH for 2 hours.
Place the icing packets that come with the frozen cinnamon rolls in hot water until melted.
Pour both icing packets over the cinnamon rolls and serve while still warm.
