This Pacman birthday cake was a surprise birthday cake for my nephew. He loves Pacman so I made one. My daughter helped to design it. The hardest part was smoothing out the ghost and Pacman. It took about an hour to mix icing and decorate. We made it with chocolate icing and white to mix the colors. The cake itself was a marble which I used a yellow cake mix and added cocoa to about one cup of yellow to make the marble.
