I keep getting air bubbles under fondant covered cakes!!! Without fail! The last cake was even dark chocolate ganache iced, and then covered in fondant and I still got air bubbles! I don't know why! I can have a great-looking smooth fondant cake and then the next morning I will go look at my cake in the fridge, and whaddyaknow, a big bubble or two have formed in random spots! Help!
That happens to me when I refrigerate my crumb coated cake before covering it in fondant. If this is what you're doing, try letting the cake come to room temp before covering it.
the same happens if the cake was frozen before covering the cake definatly needs to be room temp before covering
AIt usually happens when you don't press well the fondant to the cake, when it does happen just go with a needle and poke the air bubbles, that should work, and make sure the cake is at room temperature before covering with fondant.
AI have been having the same problem! It's driving me crazy! My cakes are room temp because I let them sit overnight after I ganache them. I'm also carefull to put the fondant on top of the cake slowly to prevent air pickets and I run over it with a fondant smoother too. I'm carefull to brush the entire cake with shortening before puting the fondant on. I wish I could figure out what I'm doing wrong.
This happened to me with my last cake, I don't do cakes too often, I had the cake covered and nearly finished decorating it I turned it around and there was a huge bubble it was at least 2 inches across. I always depended on icing alone to work as a "glue". But I'm wondering, since the cake was refrigerated and crumb coated with buttercream, should I brush the cake with some kind of edible glue before putting on the fondant? I do that when I use ganache but I'm not sure with buttercream.Thank you.
I think the "glue" was common to be piping gel, but I take a much lazier route and spray a light mist of water from a spray bottle onto the cake before putting the fondant on.
I do still get bubbles occasionally, but much less if I put it on slowly and push air out as I go. Kind of like 8th grade science class when using the microscope slides! Ha.
