I made an 8 inch cake that was specifically requested to be made out of box aswell as the butter cream store bought. I made cakes about a week prior and froze them. As soon as i took out the freezer i leveled cakes and imWhy Did My Fondant Cake Get Air Bubbles While Left OutWhy Did My Fondant Cake Get Air Bubbles While Left Outmediately started frosting them. I noticed box cakes tend to get very moist once thawed out and will break easy so i start prepping right away. I crumb coated left in fridge for an hour then recoated and placed in fridge for another half hour as soon as i took out the fridge i applied my fondant and started smoothing right away i also have noticed for me that when i apply fondant on a cold cake my smoother starts to stick due to condensation. So cake looked amazing all done. It was left in a box overnight in air conditioned room and when i looked at the cake it looked as it it had exploded with massive tears and bubbles. I thought maybe i should have refrigerated overnight but afraid of condensation i didnt. Can someone help me i have few order coming up and i dont want this to happen to a paying customer.

I don’t have a lot of experience with fondant, but I always let my cakes thaw completely before frosting them. Maybe they finally thawed while sitting out overnight and moisture seeped  into the fondant?

Or if you know that that particular box cake is very crumbly, maybe it just didn’t have a strong enough texture to hold together.

I'm thinking maybe the store bought frosting doesn't set up as firm as frosting made from scratch maybe? It perhaps had trouble supporting the weight of the fondant.

You may also have had some air pockets in there that expanded as the cake warmed up to room temp.

Oh my - what a dissapointment after making such a nice creation. My thought is somewhat along w/me_me.. the store bought icing is different than most recipes and has more moisture.  If you didn't apply the fondant tightly onto the cake air bubbles formed :(   Did you use fondant smothers to help get it firmly attached to the b'creamed cake?  Also, the temp in you home could slightly effected it all.   If it was hot and humid it would add to the cause & effect :(
