Add coffee liqueur, vodka, pumpkin pie spice, heavy cream, and ice cubes to a cocktail shaker.
Shake together for about 10 seconds.
Open the pouring spout of the shaker and pour cocktail into an old fashioned glass with a large ice cube.
Garnish with a dusting of pumpkin pie spice and a cinnamon stick.
If you don't have pre-mixed pumpkin pie spice, mix together 1 tsp ground cinnamon, 1 tsp ground ginger, ½ tsp ground nutmeg, ½ tsp ground cloves, and ½ allspice. Use ½ teaspoon of this mixture per cocktail.
