Has anyone developed a way to stop those terrible hair line cracks in buttercream? I make my buttercream from Sharon Zambito's directions exactly, coming out smooth. Yet, when I ice the cake and it sits I get those awful cracks. I mount my cakes on 1/2" foam board, use the bubble tea straws to stack them and still have them. Although, I don't always get them. So, wonder what could cause them sometimes and not other times?

Thanks,
Carol

thank you so much for posting this. i would like the solution to this too. seems lately all mine do this and i don't think they used to do it. hope someone has an answer to this and thank you in advance if you do have the answer to this problem. your a lifesaver!

could be your cake is too soft or settling? another thing is that i often have to vary the amount of coffee creamer that i add depending on the weather/humidity. added a bit too much once this summer and my icing had a few hairlines because of the heat and humidity that was really awful this summer in my area

I read on here the other day that vinegar helps with cracks.

Thanks to those that responded to my question on hair line cracks. I think that maybe I am adding a bit too much coffee creamer. Thicker icing makes more sense to me than a thinner icing. So, I will go with thicker icing and hopefully that works. I will post if this seems to be the answer.

Again thanks,
Carol
