To a glass measuring cup, add the heavy whipping cream, pumpkin puree, vanilla syrup, milk, sweetened condensed milk, and pumpkin pie spice.
Froth with a whisk for 30 seconds to 2 minutes until it's foamy and thick but not too thick so don't over whisk it. If doing it by hand, it will take a bit longer. If using an electric whisk, it'll froth really fast.
Add cold brew, iced coffee, or iced espresso to a glass along with some ice and vanilla syrup to taste, leaving about 2 to 3 inches of room at the top for the foam.
Add the pumpkin cream cold foam on top, as much or as little as you like. Sprinkle pumpkin pie spice on top and enjoy!
