Does anyone know how I can make a tiki bar on a half sheet cake? I have to make a birthday cake and she wants something with the tiki bar on it/ hawaiian theme. I am trying to figure out how to make something like this and need your help. Please help.

Do you want to do a 3D tiki bar? What if you just do a couple of rectangular layers on top of each other to form the bar section then use gumpaste/fondant to make a roof and supports (one on each side and maybe one in the middle). Do the gumpaste/fondant ahead of time so it hardens. Then you can roll out pieces of gumpaste fondant in long snakes to look like straw and put them on top of the roof. HTH.

Another thought on the roof would be to cut out gum paste leaves and cut them like they do on the gum paste palm trees (see the gallery for palm trees), but do yours in a tan or cream to simulate dead palm branches.

I saw a roof with Mini Wheats cereal for the thatch roof and it looked really good.

You could also incorporate those straw cookies that are chocolate and/or green to do the walls of the hut.
