HELP! I am dirty icing a 3 tiered wedding cake. 9hex, 12 hex and 14 square when as I'm putting my 14' square together (after being frozen) has a crack in it! Is it ok to use? This cake is due tomorrow!! I'm scared to use it but i'm afraid I don't have time to make a new one. Any help is appreciated.

It's definitely okay to use. Buttercream is great spackle. I have had cakes crack a bit and I "glue" them back together seamlessly with buttercream, by filling in the cracks with icing. Once the cake is smoothed over with the final layer of icing, the crack will not be noticeable. I wish buttercream worked on my face...

probably fine. Unless it's cracked into two pieces.

Also, be sure it is on a strong board.

it's on a cake board and a base board but i am going to put the plastic dowels and a long wooden dowel through the whole thing. The cracked layer has to support the whole cake.If I put one of the dowels too close to the crack will it make it spread?

I didn't think of the dowel part, yes if it's too close to the crack it will cause addtional cracking, unfortunately.

Thanks everybody. I have a new one in the oven. I would rather not have to sweat it out from now till tomorrow night.
