This car birthday cake was made by baking two 7×11 (casserole size) cakes and stacking then on top of one another. The top cake was cut at an angles at each end to create a hood.

Spoiler and mirrors were kit-kats. Car was frosted in dark chocolate and sprayed blue. I covered some areas with a foam number 5 and foil cut into the shape of windows before spraying. The “flames” need some improvement- that’s harder to do than I imagined!
