I made this pirate cake for Camren's 3rd birthday. It was all made out of two sheet cakes that were strategically stacked and carved. I made the sails out of gumpaste and wooden dowels, and some cannons coming out the side, also gumpaste, had sparkler candles in them.
The treasure chest is made of rice krispie treats and fondant, and the little pirate hat is gumpaste. I added some royal icing water and a black feather boa.
