I just found out that I can ship cakes across country (I live in Taiwan) on refrigerated or frozen trucks for real cheap ($7 for a 6" in a box within a box). However, I prefer to use just buttercream, when possible, which makes them harder to pack. Has anyone mailed a buttercream cake? I've read plenty on here of how to ship a fondant covered cake (which is what I shipped), but couldn't get anything to come up on a search for buttercream. Any suggestions? Frozen or refrigerated? How to pack? Thanks!

Manufacturers ship frozen cakes all the time, in a bakery box that fits tightly in a corrugated cardboard box. As long as the cake remains frozen solid the entire time, it won't get messed up.

Thanks for the replies! It didn't notify me there were answers. Anyway, I'm in Taiwan and can't get a cake safe -- although they look fun I will try shipping it frozen then. Sometimes, though, because of the high heat and humidity here, frozen decorated cakes can be tricky to thaw. They tend to bleed a lot, even properly covered and let gradually come to room temp. I might as well try it, though, right?

Thanks for giving me some ideas!
