Take a cute martini glass and place it in your fridge to chill for 30 minutes.
Take all martini ingredients in a cocktail shaker, such as one and a half ounces of white creme de cacao, half ounces of vanilla vodka, and two and a half cream.
Stir vigorously until it dissolves into the liquid to create a slightly thick foam that is stirred throughout the drink.
Take out the chilled martini glass, and pour chocolate syrup on the inner wall.
Fill the glass with ice cubes, strain, and pour the white chocolate martini into the prepared glass.
Top off with club soda or seltzer, if desired. Garnish with white chocolate chips to give a festive look.
