My last three cakes have been bubbling within hours after I cover with fondant! I'm using Satin Ice. I crumb coat and second crumb coat. I spritz with small amount of water so fondant sticks. I smooth from top down. What am I doing wrong??? Why is this happening? I hasn't happened before and all of a sudden every cake I do is having this happen HELP!

I have had several cakes do this lately also? I think it is the humidity. ?? Maybe a small section isn't adhered to cake and air gets under it? , and due to weather it "bubbles" which causes the crack? I also have NEVER had this problem. I have only been doing fondant cakes for about 8-9 months. So this is my first time dealing with summer months and fondant. Anyway, I am just guessing this is what is happening. I use both Wilton and Satin Ice. It seems to me that if the fondant is nice and soft/fresh...it is more likely to happen on the cake. Or that has been my experience with it.
Just so you know, I am not inexperienced with fondant. I really believe it is a weather issue. I did 3 cakes this weekend, our humidity was down..but not non-existent. I had one of the tiers bubble and tear. ? The other 3 cakes were fine. (2 single tier cakes and 1 double tiered cake)

yeah this has been exactly my experience as well. And now that I think about it, it's only happened when I've used Satin Ice - White. And my husband and I have both been saying that the white in particular feels extremely soft/pliable. I wonder if that has something to do with it. Should I maybe be adding more powdered sugar to it to help it not be so soft? I think I'm going to have to take the fondant off of one of my cakes and completely redo it

AMine just did the same. Looked great yesterday and today it bubbled and got a huge crack in the top tier. It has never happened to me before but this is my first summer making these cakes so Im wondering if its the humidity/heat as well. I live in texas. Anyone reccomend a fondant that wont do that in texas? I use an mmf.

ADid they change something with the Satin Ice formula??? I have been having the same problem- and the fondant feels much softer! UGH!!!
