To make the syrup, combine pumpkin puree, pumpkin spice seasoning, sugar, and water in a small saucepan.
Whisk mixture over medium-low heat until it comes to a simmer.
Simmer for 5 minutes, stirring frequently. Remove from heat and cool.
Transfer cooled syrup to an airtight container and store in the refrigerator.
Pumpkin Spice Latte
Combine 2-3 tablespoons of the pumpkin spice syrup with steamed milk and espresso.
For an iced latte, pour over 1 cup of ice. Blend with 1 cup of ice fore a frappuccino.
Top with whipped cream or milk foam and serve.
Notes
Pumpkin spice syrup will make approximately 18 drinks. Nutrition calculations are for 1 latte. You can use a concentrated coffee like cold brew in place of the espresso.Be sure the espresso and pumpkin spice syrup are fully cooled before adding to the iced pumpkin spice latte or frappe so they don't melt the ice before chilling the drink.For a layered look, add pumpkin syrup, then milk, then espresso, then foam or whipped cream. Drink should be stirred together before enjoying.
