My son wanted an airplane cake for his 3rd birthday, so, thanks to inspiration from Khym, this is what he got. It was a lot of fun to make, although I did have some trouble with the airplanes (he got a hold of them while they were drying and broke some of the the propellers and messed up a few of the wings). Luckily I caught him in the act and was able to fix them. He absolutely loved the cake and is still talking about it months later.
