Add the pumpkin syrup to a cup, and then brew two shots of espresso over the top.
Stir until the syrup and espresso are fully combined.
For an Iced PSL: Add in the 2% milk and ice, and then stir to combine. For a Hot PSL, steam the milk first before pouring over pumpkin espresso mixture.
Add whipped cream and a sprinkle of pumpkin pie spice over the top and enjoy.
