MMF on chocolate cake, the tires are double-stacked Oreos with black MMF painted on which makes it look like real tread! LOL I had a good time because I made the cake a week before, froze it, took my time experimenting with the decorative parts (lots of mistakes made but mmf looks just like new when you flip it over!) and found that shiny features of cars like windows and such look really slick when you watercolor with foodcoloring and let it dry for a few days. Needless to say - my kids actually had a blast helping me with it and they are (now) 4 and 5 years old. What fun it is to paint water on a cake to melt the powdered sugar residue? Instant artists!
