Here are the details...
It's a 9" Devil's Food cake sliced into 3 layers with a crumb (thin) coating of ganache between each layer, on the top and sides. The whole cake is then covered in rolled "brown" fondant which was made by kneading vanilla and chocolate fondant together and rolling it very thin. The rope on the bottom and the frill on the side is chocolate fondant. The boulders and the Flintstone car is made out of modeling chocolate. The stand and the circular disk is pastillage which is formed from powdered sugar, glucose and gelatin and allowed to dry firm. (If you add cinnamon during mixing, you create Altoids). Fred's portrait is done by mixing cocoa powder and melted cocoa butter. Fun and completely edible.
