Add apple cider, vodka, pumpkin puree, pumpkin spice liqueur, syrup, pumpkin pie spice, and cinnamon to a cocktail shaker.
Fill shaker halfway with ice.
Shake for 15–20 seconds until chilled.
Strain into a tall glass filled with fresh ice.
Garnish with cinnamon stick, whipped cream, or nutmeg as desired.
Notes
Use maple syrup for deeper flavor. Pumpkin spice creamer can replace puree for a creamier texture. Add club soda for a lighter drink, or Irish cream for a dessert-style cocktail. Freshly grated nutmeg offers a better aroma than pre-ground.
