A classic espresso martini is made with coffee liqueur, simple syrup, and vodka, and it's often served chilled and garnished with coffee beans or a chocolate drizzle. In this frozen espresso martini, we've put a frosty twist on the traditional by swapping the brewed espresso for cold brew ice cubes. Blending in the coffee ice cubes helps keep the drink frozen without diluting the flavor. Our Test Kitchen sweetened the drink with a tablespoon of sugar, but you could easily add more or less to your taste. A pinch of flaky sea salt is an unexpected but totally welcome finish—it helps balance the bitter flavor of the coffee in the cocktail. The finished drink should be smooth, slightly bitter, and subtly sweet with flavors of caramel and vanilla.

How to Make Frozen Espresso Martinis for a Crowd

Our recipe makes two frozen espresso martinis but can easily be scaled to serve a crowd at a party. Simply stash a large batch of the cold brew concentrate ice cubes in the freezer and your prep work is done. When guests arrive, blend them up with vodka and coffee liqueur. Pour a little bottled chocolate syrup on a small plate and dip the rims of the martini glasses until coated. If desired, dip the chocolate-coated rims in finely chopped dark chocolate or finely crushed chocolate wafer cookies. Drizzle the inside of the martini glasses with additional chocolate syrup, then pour the frozen espresso martini blend to fill a glass for each guest.
