I am going to be using whipped ganache as a filling for a 4 tiered stacked cake. I want to get the cakes filled and a crumb coat of whipped ganache on them when i freeze them so i don't have to rush. I want to have them done and ready for fondant when i thaw them. You think this is safe? Has anyone tried freezing whipped ganache? Any tips to properly freeze and how to thaw them?

I've only froze the ganache before it was put on the cake. But it was fine when I thawed it and put on the cake. sorry not much help.

They should freeze just fine, even with the ganache. Make sure to wrap them well in plastic wrap AND aluminum foil, to prevent freezer burn, and let them thaw completely before unwrapping them again.

Good luck!

Ganache will freeze fine. I freeze truffles all the time which are basically thick ganache (chocolate and whipping cream).
