one more question .. Will the buttercream frosting melt or change shape if its kept outside ?
I would appreciate it if I got an answer right away ! Help !!
It's ok to refrigerate cupcakes. Just keep them well wrapped/covered. They will harden slightly from the cold but they will come back to room temperature just fine.
As for your frosting, Most will do the same but I think it comes down to what kind of recipe you are using. For me, this affects when and how I ice/ store them. A crusting buttercream, for example, whether you refrigerate or not, will leave a slight "hardness" on the surface of the icing which isn't a huge deal, but frosting too far in advanced or leaving them to the air can worsen the crust. This is also a very sturdy icing which won't "melt or change shape" and doesn't require refrigeration so it has its benefits. If I use this on cupcakes, I try to ice them as close to serving as possible and keep them well covered. Anything like a cream cheese based though, needs to be refrigerated, will soften when left out and is not good in any kind of heat. So probably not a good choice for a school function. Hope this helped.
