Don't know if I am in the right forum or not but...I have been watching a cake decorating show on WE lately and one particular baker uses what looks like a cake pan (but has no bottom)to cut his cakes. In other words it looks like a large cookie or gumpaste cutter but they are large enough to cut cake. He bakes sheet cakes and uses the cutters to cut the actual round or square cake in the size he needs. This would certainly eliminate any side trimming because each layer would be exactly the same. Does anyone now where to get such a product? I have looked online, but nothing as of yet.
Thanks!

They're called cake rings.

And thanks for reminding me about these. I need to get some!

Well that makes sense...any idea where I can order them?
thanks again : )

I got mine (along with my mini cake/cheesecake pans) here:
