Has this happened to you? This is a first for me after many many cakes. Not sure what happened this time. Maybe a trapped air bubble in the filling? I refrigerate my cakes after they are baked, cooled and wrapped in plastic. The next day I tort and fill. I chill the tiers in the fridge as I work. Covered it in fondant and chilled again as per usual.

This time when I had it out to decorate a very large air bubble between the buttercream and fondant appeared after about an hour or so. I pierced it with a pin and it deflated a bit, but I had to cover the area with a flower.

Any suggestions on what might have happened? Thanks in advance.

There is a thread about this but of course I can't find it because of problems with the search function. I think someone said they could fix the problem by sticking something (like maybe a coffee stirrer) in through the fondant, sucking the air out, and smoothing over the hole. I think if you had a hypodermic with needle, you could do the same thing and even have a smaller hole to fix.

I hope someone else finds the thread and posts it.

ahhh. interesting. I looked too and didnt see the post. Good advice. thanks!

You can use a sterile needle to poke a hole in the bubble and let the air out. Works like a charm!

Ah.....finally found the one I was thinking of:
