⅔ chocolate cake

A 2/3 chocolate cake is obtained by eating one bite of a chocolate cake. It heals five hitpoints when eaten, and then turns into a chocolate slice, which also heals five hitpoints. It cannot be obtained by sprinkling chocolate dust onto a regular 2/3 cake. There is no store that sells these, and they are difficult to buy on the Grand Exchange. However, this does not matter because a full chocolate cake heals more.
