This is actually 2 11x15 cakes side by side. Triple layers, 1/2 french vanilla with vanilla creme filling and 1/2 chocolate fudge with chocolate mousse filling, buttercream frosting. The car is made from rice krispy treat, and covered in marshmallow fondant. I cut the windshield from a plastic transfer sheet. The trees are rkt, covered in buttercream. The car was a huge challenge for me. It is definitely not exact, not even close, but I like the car-toonish result I got. :~) I did use cardboard underneath for support.
