If you like espresso and like martinis this is for you. But just a warning: regardless of what you have heard in the past, drinking coffee does not make you sober and this drink will not cancel out the alcohol.
6 oz vodka
6 oz Kahlua
4 oz creme de cacao
4 oz chilled, double strength espresso
Fill a cocktail shaker with ice
Add half of the vodka, Kahlua, creme de cacao, and espresso
Shake well. The mixture will become foamy
Pour the mixture into 2 chilled martini glasses
Repeat for 2 more cocktails.
You can use instant espresso or double brew coffee. To double brew coffee you brew once and them run the coffee back through a second time with the first coffee as the water.
