I piped a wedding cake yesterday with the same frosting I always use (okay I was way tired and maybe mixed it a bit different, but I don't think so) . When I piped it it didn't come out smooth from the tips.

The piped icing kind of "cracked a bit around all the edges but it looked lacy and pretty so I just went with it (the cake picture is in my photos). Why would my icing do this?

My only thought was...was it thinned out enough. The cake is absolutely beautiful though! Great job!

Maybe it had some air bubbles? I don't like to pipe with icing that's been in the bag for many hours or overnight because it develops too many air bubbles. I always pipe with freshly beaten icing.

First of all, gorgeoussss cake.

Secondly...it does definitely sound like air bubbles. I think if I mix for too long this happens. If you were new to caking I'd wonder if you just weren't squeezing hard enough/moving your bag too fast but I doubt that. It probably needed to be thinned just a dab more!

yeah- it was thin enough-(I think) but I definitely beat the heck outta it because I was doing something else when I whipped it up! So maybe gazillions of tiny air bubbles.........

this is my 3rd wedding cake- so thanks for the compliments. I have another one in 2 weeks that will have all this piping too and I don't want the "lacy" look on it!
