My daughter's 13th b-day. Chest and gold bar are cake, lid is rice krispies treats w/ choc melts on underside. Homemade marshmallow fondant on bar and for treasure map. Map writing painted with thinned icing colour. Modeling clay details on chest. All the jewels are candies and edible. Sand is graham wafer crumbs and brown sugar. The girls thought it was a piece of furniture, not a cake!
