I made this "Rock Band" cake for my son's 13th birthday. The guitar was cut out from a 9X13 sheet cake. The drums are 4 mini cakes with melted white chocolate for the drum pad. Drum sticks are made from banana taffy and the microphone is a yodel with a rice crispy treat dipped in colored chocolate for the top. The only non edible part was the whammy bar on the guitar.
