Silly question for professionals, I know, but here it goes. Does anyone know how long store bought frosting will last when left out of the fridge? I am putting together a last minute cake for a friend and I have some left over frosting from Halloween cookies that I could use to make a small "The Incredibles" logo with. But I took it out of the fridge yesterday. I would hate to make a whole batch of homemade icing for something so small.
I don't use store bought icing but it should last like any other buttercream. Icings are really quite safe for quite awhile. The sugar acts as a preservative. Grocery stores keep their iced products on the shelf for days (or weeks) and they use pre-made icing. You'll be okay with it especially if you just took it out of the fridge.
The icing should be fine!
That is what I was thinking....thanks for humoring me and my silly question!
