Instructions:

Fill a martini shaker with crushed ice cubes.

Pour in the vodka and white creme de cocoa over the ice cubes.

Shake it for about 30 seconds until it's chilled through and well mixed together.

Strain into a frozen chocolate rimmed martini glass or one that has been lined with chocolate syrup on the inside of the glass around the edges at least an inch up from the bottom of your glass if you wish to do so (optional).
