Put some chocolate syrup on a small plate and crushed peanuts on another. Dip the rim of the glass into the syrup then into the crushed peanuts, coating the rim evenly.
Fill a cocktail shaker with ice cubes. Pour in the Mozart Dark Chocolate Liqueur, Mozart Chocolate Cream Liqueur, vodka, vanilla, half-and-half, and caramel sauce.
Vigorously shake for about 15-20 seconds. Carefully strain the cocktail into the prepared martini glass
Optionally, garnish with a sprinkle of crushed peanuts on top and a mini Snickers bar on the rim of the glass
