Shelf Life of Buttercream?
I was wondering if you guys leave your buttercream filled/iced cakes out at room tempature for extended periods of time?
I get nervous not refrigerating EVERYTHING, but was told it was ok to leave out.
If you leave a stick of butter at room temp for several days, it starts to taste like blue cheese.
I would not leave a cream cheese or buttercream frosting out of the refrigerator for more than a couple of hours, not at all in 70 plus temperatures. The flavor won't change in that short a time, but the frosting will get too soft, perhaps even melt and run.
