Place cinnamon and granulated Pure Via on a small plate.
Brush the rims of two glasses with water (or simple syrup if you have it) and turn glasses upside down on plate to coat rims in cinnamon Pure Via mixture.
In a shaker filled with ice add, 1 cup green tea, 1 Tbsp pumpkin puree, ¼ tsp Pure Via, and 1 ½ oz. vodka. Shake well.
Strain into rimmed glass filled with ice. Garnish with a cinnamon stick if desired.
Repeat with remaining tea, pumpkin puree, Pure Via liquid, and vodka for second cocktail.
