freezing cinnamon rolls - bake -freeze-allow to reach room temp - reheat for how long - ice -ice does that

You don't need to thaw. I nuke in the microwave, 30 seconds at a time until warm/hot. In my microwave, it takes about 55 seconds.

If you don't do or have a microwave, wrap loosely in foil and pop into a toaster oven or oven at 325F for about 15 minutes or so. Depends on how hot your oven runs.
