This cake was made for a co-worker who's nickname is Weenie. The bun is a chocolate cake carved into the shape of the bun, covered in buttercream. The weiner is chocolate cake covered in fondant, grill marks are painted on with brown food coloring. Ketchup & mustard are buttercream. Relish, onions and chips are fondant. I don't know if you can see it or not, but the chips have "salt" (sugar) sprinkles on them.
