I browsed this site for Lightning McQueen cakes and finally decided to use a character shaped pan. It was a devils food cake and Wiltons decorator frosting (tweaked with my secret ingredients). I looked at other Lightning McQueen cakes as a model.
Another Lightning McQueen Cake
Well basically the car was done by a character pan and frosted with buttercream icing. Along with just cutting the next cake (#2) was done by hand. I love the way the Lightning McQueen turned out and so did the people that ordered it.
