In a small saucepan, combine the pumpkin puree, condensed milk, pumpkin pie spice, vanilla, and salt over medium-low heat.
Stir frequently for about 5 minutes or until everything is incorporated and a pourable consistency is reached. Remove from the heat and let cool. Store in an airtight bottle.
To make a latte, mix 2 shots of espresso with 1 ounce (2 tablespoons) of the pumpkin spice sauce.
Steam 6-8 ounces (¾ to 1 cup) of milk and pour into the mug and enjoy!
