I made this one for my husband's surprise birthday luau. It is double layer pound cake 10 inch and 8 inch. The tiki hut was 2 cupcakes stacked with a cocktail umbrella for the roof. The cake was iced in chocolate buttercream, then decorated over the top with regular buttercream. The flowers, rocks, and palm leaves are all royal icing. I was a little disappointed that the palm leaves didn't stand out like I would have liked for them to have. Thanks to all of the other ccers for ideas!
