With a lot of inspiration from the cakes at CC.com-For my son's 4th birthday. Baked a 9x13 sheet cake and two 9 inch cakes. My husband "designed" the track for me. I dont like the taste of black icing, opted for chocolate instead for track and flag design around bottom. Washed cars well and placed on track. My son loved it! A lot of work, but very proud for a first attempt at a cake that I designed myself! Thanks to all the creative people that gave me the courage to attempt it.
