Begin by melting the white chocolate in a microwave-safe bowl for about 30 seconds to 1 minute, stirring until smooth. Dip the rims of two martini glasses into the melted chocolate, and roll the chocolate-covered rims in finely crushed gingerbread cookies. Set aside to cool.

In a cocktail shaker, combine gingerbread vodka, half-and-half or cream, Irish cream, coffee liqueur, and ground ginger. Fill with ice and shake well.

Vigorously shake the cocktail mixture for about 15 to 20 seconds until the shaker is cold.

Strain the mixture into the prepared glasses. Ensure a velvety finish.

Top each cocktail with a generous dollop of whipped cream and sprinkle ground cinnamon for garnish.
