Edible chocolate shot glasses are available on Amazon, as of January 2015. They are also available at some high-end chocolatiers, such as Astor and other online novelty stores. Spencer's Gifts, located in many malls, is another good source for edible shot glasses.
Rather than purchasing chocolate shot glasses, sometimes "called liqueur cups," chocolate lovers can make these delicious treats at home. Recipes vary in complexity and utensils needed. There is a wide variety of choices as far as types of chocolate and other ingredients used. Shot glasses available for purchase are typically limited to two flavors: milk chocolate and dark chocolate.
