my daughter wanted a Hannah Montana guitar cake so I made it. I used graham crackers for the neck of the guitar and used Hershey kisses for the knobs that holds the strings.
I used an 11x15x2 cake pan and cut a guitar shape out of it. I made purple icing and brown icing and I also used Andy mints.
It took 2 cakes to fill this pan.
