Mudslide is a popular American cocktail made with a combination of vodka, coffee liqueur (e.g. Kahlua), and cream liqueur (e.g. Baileys). In order to prepare it, all ingredients are shaken with ice, then strained into a glass filled with ice cubes.
Alternatively, all ingredients can be blended together until smooth, poured into a glass, then drizzled with chocolate syrup, if desired. It is believed that the first Mudslide was prepared during the 1950s at the Wreck Bar in the Cayman Islands.
