Oh, absolutely. This is the pro move. Buttercream freezes like a champ for up to three months. Cream cheese frosting can freeze, but the texture might get a little grainy when thawed. Whipped cream frostings? Don’t even try. They’ll cry more than a toddler who dropped their ice cream.
To thaw, just move it to the fridge overnight, then bring it to room temperature and re-whip. It’s like a little resurrection ceremony for your frosting. Spread the good news.
