This was requested by a friend's son who has, sadly, left the Lightning McQueen stage. He saw this cake in a Family Fun magazine and insisted this was the one he wanted.
I used donut holes, chocolate cereal, pretzel sticks, pretzel rods, and fruit roll-ups for this cake. And why is it nearly impossible to find solid colored fruit roll-ups? Makes my job harder. Inside is dark chocolate cake covered with my lovely chocolate buttercream.
