Heat the milk and sweetened condensed milk in a small saucepan until warm. Pour the mixture into a 16 oz. mason jar (perfect for storing) and add in the pumpkin pie spice and canned pumpkin.

Shake well for about 30 seconds so that the ingredients mix. Heating the milk and sweetened condensed milk allows the pumpkin pie spice to mix and not be grainy.

Store in the fridge and make sure to shake well before using.
