For the New Yorkers in the bunch, the Chocolate Egg Cream Shot uses real cream and chocolate liqueur. (Keep this one away from the kiddos.) To make a "mocktail" version, you can substitute chocolate-flavored sugar syrup (such as Torani) for the liqueur. The Chocolate Egg Cream shot is made by blogger Faith Kramer.

Pour cream in a shot or liqueur glass. Add seltzer. Gently stir. Slowly pour chocolate liqueur in the center of drink. Do not mix. Serve immediately.
