I made this cake while in the states for a 5 year-old's birthday. I tried to copy the actual Hannah Montana guitar as best as I could. It is all buttercream frosting. Single layer that fed about 20 people. She loved it and I was very pleased with the way it turned out. I will be back in Okinawa ready for more orders at the end of October. Email me and we can plan your next occassion!
