Add all ingredients to a cocktail shaker. Add one cup ice. Shake for 10 to 15 seconds. Strain into chilled coupe glass.
Garnish foam with 3 whole coffee beans.
Notes
Fresh espresso is the best choice, but if you don't have an espresso machine then using an espresso powder to make a shot of espresso is a great substitute. Cold brew coffee concentrate can also be substituted.Regular brewed coffee will not give you the intense coffee flavor needed for this perfect after-dinner drink so for best results, stick to espresso.Experiment with adding different liquors such as Amaretto, Frangelico, or Rumchata.
