Do I have to refrigerate buttercream frosting (crisco, conf. sugar, meringue powder)? Do I have to refrigerate all cakes after they are decorated? What do you do if you don't have enough room in your frig? Have you all had to get another frig? thanks. sunflowerfreak
Buttercream of the type you describe stays good at room temp for a few days (it shouldn't be super hot, though--you don't want melting.)
If you have a perishable filling, however, you should refrigerate your cake.
There have been many forum threads on this topic. Do a search for "refrigeration" and you should find lots of info.
No, for that base icing, you would NOT have to refrigerate the frosting. The SUGAR acts as the preservative. However, to keep it FRESH tasting, you'll want to keep it in the fridge in a SEALED container, and then whip it a little before using.
Cakes don't need to be refrigerated, unless they're out at your house for more than a couple days. Sometimes, refrigeration can cause unwanted odors, tastes, etc.
Now, if a frosting has milk/butter ingredients, you'll want to refrigerate it, until decorating. (Then you'll want to bring to room temp. before decorating.)
I usually freeze my frosting in bulk, then defrost as needed. I figure if I'm going to be mixing it up, I might as well do three or four batches at a time, know what I mean?
Hope this helps,

I use Colette Peters' buttercream recipe which contains both butter and milk. It, too, stays fresh at room temperature for a few days. The sugar acts as a preservative here too.
