A very much Cars inspired 3rd birthday cake for my step-son. Tallest cake I have made (It was close to 3ft tall" and my first time airbrushing. I constructed the support out of pvc. The tires are a vanilla cake with a chocolate fudge filling and the base of the piston cup is raspberry cake with a lemon cheesecake mousse filling. The cozy cone motel and top of the piston cup are RKT. The entire cake is covered in MMF and airbrushed. The base was airbrushed and graham crackers that were crushed by the birthday boy (he had SO much fun smashing them) were added to make the dirt track look like a J. The wings on the piston cup ended up a tad wonky (darn gravity) but all in all it was a big hit for the birthday boy and everyone else at the party.
