I made a cake last night. It's filled with buttercream and covered in fondant with 3 layers. THis morning, the buttercream was seeping out the bottom of the fondant. Now there's a big airbubble in the fondant and it's still leaking out and there's a pile of buttercream behind my cake. WHat makes this happen and how to I fix/prevent it? Did I not let the buttercream set long enough before covering it with fondant?

Are you using a Crisco recipe? It sounds like a "new Crisco" issue. Mine did that & I didn't have fondant on it. I've also had it happen when trying out other shortenings.
