I don't know if you can see in the picture what's happened but i put fondant on my cake last night then finished decoration today (the birdcage effect, flowers etc) and was quite pleased until i turned it and noticed this area where the buttercream is bursting out of the fondant.
What has caused It? Did i wet my fondant too much? Did i push my flowers on too hard? It looks like its getting worse...
Any quick and easy way of fixing It? X
the quick fix is to stick some more flowers on the hole! No one will know. No idea why your fondant is doing that - perhaps you had a small section that was rolled too thin.
I thought about that but it appears that the fondant is bulging out as a lump. Going to get ready for a party to take the cake to so wll see if i have time :-)
This is discussed many times on this and other sites. Some call them 'blowouts' - & there are other names for it.. There are as many ways to 'prevent' this from happening as there are names for the problem :( Mostly it is caused by not getting the fondant tight against the cake allowing air to be trapped in, then it pushes (erupts) it's way out. Probably the most important thing is to be sure the cake is covered w/an even layer of icing or piping gel and that you massage the fondant onto the cake well.
As for the lump......again it is air traped so take a pin and stick it into the fondant lump from the underside and gently push out the air.
