I made this cake a couple of weeks ago for a client turning 5. He told me he wanted 'Cars' with a few of the characters and a race track. This was going to be a pretty good size party and needed to feed at least 50 people. I decided to incorporate a few different scenes from the movie and make it a 3 level cake.
I covered the whole cake in different colors of butter cream and then added fondant accents. I made the base the race track. I cut out squares of black and while fondant to 'glue' around the sides. Crushed up Oreo's were the track complete with toy cars of the racers. The second level was the desert scene. I made some cactus and mountain looking areas out of fondant. The top level was the sky complete with Mater jumping through his ring of fire(like on the mini cartoons). This also has the waterfall coming down into the desert, and clouds out of fondant. I made some tires, barrels, haystacks, and name and #5 out of fondant and let them dry. I assembled the cake and used my Shark steamer to shine it all up and there you go. A very happy 5 year old and plenty of cake to go around.
