Help! I delivered a cake this morning only to see when I got there that the fondant was starting to crack and bubble. I had no issues last night when I was decorating it. I used Satin Ice fondant. I'm only praying the cracks don't get any bigger before their party this afternoon. Is it the humdity or vibration in the car? How do I fix it?

Thank you for your help.

What did you crumbcoat the cake with under the fondant?

I crumbcoated with crusting buttercream.

Sometimes if the crumbcoat is not completely smooth air bubbles will form under the fondant. Just pop them with a pin and gently smooth them out.

I did that with the bubbles but I'm more concerned about the cracks. I hope they don't get worse.

Now when you say cracks are they like elephant skin when you lay the fondant on the cake or is the fondant cracking and literally splitting away from the cake. I only ask because that happened one time to me about two years ago it was one of the first cakes I made. The cake was fine after I covered it, it actually looked great and as the day went on one specific spot on the cake started to get a huge air bubble in it and the fondant literally started to separate from itself. It was a huge mess, I hope that doesn't happen to yours but looking back now I know what I did wrong. I should of popped the bubble ans smoothed it out but I never did that and it got worse and worse.

If it's cracking near the bottom of the tiers, the problem may be due to the cake settling and/or the dowels cut too short.

It is just cracking at randon spots. On both tiers. I'm just going to hold my breath. The customer is not concerned with them, but I AM!

good luck!

Thank you everyone for your help!
