Place 1 1/2 ounces rye whiskey or bourbon, 1 ounce apple cider, 1/2 ounce sweet vermouth, 1/4 teaspoon Angostura bitters, and 1 pinch pumpkin pie spice in a mixing glass or cocktail shaker. Add enough ice to fill the mixing glass about half-full. Stir until the cocktail is very chilled, about 30 seconds.
