In a cocktail shaker, mix together 2 ounces of bourbon, 1 ounce of pumpkin puree, ½ ounce of pure maple syrup, ¼ teaspoon of vanilla extract, and ¼ teaspoon of pumpkin pie spice.

Fill the shaker with ice and shake vigorously for about 15-20 seconds until the shaker feels cold to the touch.

Using a fine mesh strainer, strain the mixture into an old-fashioned glass filled with fresh ice.

Optionally garnish your cocktail with a light sprinkle of pumpkin pie spice or a cinnamon stick.
