Well, Brian is a 7 year old boy who is simply infatuated with cars; real functioning cars and toy cars. So it seemed like the obvious thing to make his birthday cake in the formation of a car.
It's quite easy to make, but the details are what I think are most important. I used edible rice paper for the windows, and orange flavored gumdrops as blinkers. I used Chocolate Pinwheel cookies as wheels from the local grocery store, but you can use any kind really. (preferably your child's faveorite)
