A rich and smooth espresso martini made with a homemade coffee liqueur that combines fresh brewed coffee, brown sugar, vanilla, and vodka for a sophisticated and crowd-pleasing cocktail.
Use freshly brewed coffee for best flavor. Keep heat low when dissolving sugar to avoid evaporating alcohol. Shake vigorously to create a frothy top. Chill glassware before serving. Homemade coffee liqueur keeps up to two weeks refrigerated. Adjust sweetness with simple syrup to taste.
