In a mason jar or medium bowl, combine heavy whipping cream, whole milk, canned pumpkin puree, vanilla syrup, and pumpkin pie spice. Froth the mixture for about 10-20 seconds until it becomes light and creamy. Set aside.

Fill a tall glass with ice cubes. Pour in milk of choice and add chai tea concentrate, stirring gently to combine.

Spoon the prepared pumpkin cold foam over the iced chai latte, and optionally sprinkle with pumpkin pie spice before serving.
