The monitor is three cakes stacked, baked in loaf pans. The mouse is a piece of cake frosted to look like a computer mouse. The keyboard cake was cut from a 11X13 sheet cake. To make the keyboard I used magic mold (safe for food) that i had bought at a craft store and molded an actual computer keyboard. I filled the mold with white chocolate and once it hardened I used black buttercream to write the letters on the keys.
