Add all of the ingredients for the pumpkin pie spice (except the vanilla) into a small to medium saucepan. Bring to a simmer and simmer for 10 minutes.
Once your mixture has simmered, allow to cool.
Once cooled, pour into a storage container(s).
To make a hot latte, put your instant coffee and hot water (or your espresso) into a glass. Add 2-4 tablespoons of the pumpkin spice syrup. Froth a little bit.
Use 6-8 ounces of hot milk of choice. Add 1 tablespoon of pumpkin spice syrup. Froth.
If you froth the mixture, after adding the milk, you will have a little foam on top. You can definitely stop here. The foam this makes is very nice. Sprinkle with pumpkin pie spice and you have a nice fp pumpkin spice latte, if you used low-fat and fat-free milk.
Stop here if desired. If not, let's make a pumpkin spice foam. In a small glass add 1 tablespoon of heavy cream, 1 tablespoon of milk, and 1 tablespoon of the pumpkin spice syrup. I warmed the mixture up. Froth. The froth is nice, but the foam from just the milk and syrup was great.
Pour on top of the latte. Sprinkle with pumpkin pie spice, if desired.
