Fill a rocks glass with ice cubes to cool it down while you gather the ingredients and prepare the cocktail.
In a mixing glass, add 2 oz of vodka and 1 oz of coffee liqueur. Stir well until the components are thoroughly mixed.
Take out the ice cubes from the rocks glass, and replace them with fresh ice. Strain the blended concoction into the refreshed glass over the new ice.
If you want to get fancy, adorn the Black Russian with a lemon twist, orange slice, or cherry.
