I made this cake for my son's 3rd bday! Chocolate cupcakes, yellow cake, and cocoa rice krispies for the "bleachers" Took me about 2 hours not including bake time. I got the idea from 3 different cakes on here! First time making a cake like this! None of the cars are edible tho, would have been way to much work. Next time I think I would try to make them.
