A HUGE thank you to nefcook21 for this wonderful idea. My son absolutely loved this cake. 1/2 yellow, 1/2 chocolate with all BC. In the interest of time I purchased tubes of wiltons green and yellow. I tinted the red. Also since I don't care to work with fondant I used wilton's chocolate BC tinted black and applied with x-wide tip. I also added the Mach 5 circle since it was his 5th birthday. This was one of the easiest cake I've made to date.
