Serve up a little black magic in the form of a cocktail made with vodka that's as dark as night—with a scoop of ghostly-white vanilla ice cream floating on top. It's rich, chocolatey, and absolutely spook-tacular.
In a glass, combine vodka and creme de cacao, and set aside. Place a scoop of ice cream in a highball glass, and slowly pour vodka mixture over ice cream. Garnish with nutmeg; serve immediately.
