Agreed, except one time I was really impressed by the cupcakes at Gigis in Memphis. They were freaking delicious. Every other time I have had "gourmet" cupcakes they were meh at best and almost impossible to actually eat because they had so much frosting on them.
I liked Gigi's even though I felt like shite after eating one. But one time I went and asked them how long they would keep (it was summer). The guy told me their recipe for the frosting is 75% butter and 25% sugar and flavoring. After that, I vowed to never eat one again. Too much junk.
As for FroYo collapsing, I don't think it's any time soon. They're marketed so well as being a "healthy" snack that people don't hesitate to get some.
