I really need some ideas on how to do a hawaiian themed cake for a guy.

What about doing an Aloha Shirt with a gawdy Hawaiin print on it?

Something like replicating this as a cake?

You could always use a tiki god as inspiration and have the main cake be a tiki and have a couple of palm trees come over the top of the tiki, to make it a little more hawaiian...or you could just make it look like a luau spread with traditional food.

Here is my sketch of one I am doing in a couple of months for a Luau.

Here's a rather easy one I did: http://cakecentral.com/modules.php?name=gallery&file=displayimage&pid=1333806
Just hollor if you want any info

My friend had a Hawaiian theme & I made this ( w RKT booblages )

I've seen some really cute tiki hut/surf shack cakes in the gallery here.

And this one isn't a tiki hut, but it's really tropical and beautiful.

I hope this helps a little bit!!

Thanks for all the ideas. I definately need to decide which route I am going to go with it.
