The classic espresso martini is getting a twist with cold brew coffee, peanut butter whiskey, and some heavy cream foam on top. This is the perfect sophisticated cocktail to mix up with Skrewball, Skatter Brain, or Bird Dog.
Add coffee liqueur, espresso cold brew, peanut butter whiskey, and ½ ounce of simple syrup to a shaker filled with ice. Shake until well chilled, about 30 seconds.
