The characters, signs, and the background scenes of Radiator Springs are all made of sugar cookies baked on bamboo skewers instead of lollipop sticks. They were a lot thinner and blended into the background better. I painted the background cookies with Royal icing, then used a mixture of meringue powder and water to wet it down and added coarse brown sugar crystals to create a sandy or rocky texture. I also sprinkled the top of the cake with the crystals to look like the desert. The black asphalt and orange cones formed to hold the candles, are made from homemade rolled fondant that tastes like marshmallows. The writing says "Happy Birthday" in the front and "Happy Motoring" in the back.
