Can you refrigerate a buttercream iced cake overnight and then cover it with fondant the next day? Wil the butter cream get soft again at room temperature? I am talking about a powder sugar based buttercream...
My questions is because when you leave powder based buttercream air out without covering it will crust and I don't want the buttercream to crystalize on the cakes...
it will crust in the fridge too.
if you are covering it in fondant, does it matter if it crusts?
you could cover it lightly with plastic wrap - or maybe mist it with water using an airbrush before you cover it in fondant.
You can refrigerate it. It's going to crust either way, but you can still fondant it the next day.
if it is a crusting buttercream, it's gonna crust no matter what you do (fridge or on the counter). if you need to put it in the fridge tonight and can't fondant it tonight, go ahead... tomorrow, when you're ready to put the fondant on it, you can do a couple of things... mist it (LIGHTLY) as stated above w/water OR you can take a damp papertowel and lay it on it briefly until the bc softens up.
