Cinnamon Roll Reheating Instructions:
From frozen: Remove plastic lid and cover with foil. Preheat oven to 350. Bake for 20-25 minutes or until warm through. Snip the end off the frosting packet and squeeze (from the top) onto hot cinnamon rolls. If the frosting packet was frozen, you can thaw overnight or microwave 8 seconds at a time until thawed.
If you thaw them on the counter overnight use the same instructions but check them after 10 minutes. It may take a little longer but not much.
