AI recently did this cake and I covered the cakes directly out of the fridge. About 1 hour after they had air bubbles and I think what you call blow outs? I used satin ice. Why did it do this? Advice?[IMG]http://cakecentral.com/content/type/61/id/3106222/width/200/height/400[/IMG]
If you let them adjust to room temp first you will have less problems. If the air inside is expanding as it warms up....you are bound to have problems. x
As Rosie mention let your cakes adjust to room temp. before you start covering your cakes.
