This chocolaty cocktail is dangerously delicious. I love to drizzle a squiggly design of chocolate syrup in the martini glass before shaking and pouring the martini into it. It's a great nightcap your guests are sure to enjoy.
Drizzle chocolate syrup into a martini glass. Set aside.
Combine the chocolate liqueur, Irish cream, whipping cream, and vodka in an ice-filled cocktail shaker. Shake about 30 seconds or until thoroughly chilled. Strain into the martini glass and serve.
