This was for an 8 year old boy's birthday. Lightning McQueen (from Disney's "Cars") was a yellow cake with my special whipped buttercream (use heavy whipping cream instead of water and whip it for about 10 min), homemade marshmallow fondant and gumpaste/royal icing details. The car was carved by hand - I think cakes turn out best when carved by hand. THANKS!!! ENJOY!!!
