01 - In a small saucepan over medium heat, whisk together pumpkin purée, pumpkin pie spice, and sugar. Heat until warmed and fragrant, about 1 minute.
02 - Slowly add milk, whisking constantly. Heat until steaming but not boiling, ensuring the pumpkin mixture fully incorporates into the liquid.
03 - Remove from heat and whisk in vanilla extract until evenly distributed throughout the mixture.
04 - Froth the milk mixture using a handheld frother, whisk vigorously, or blend briefly until foamy and creamy texture is achieved.
05 - Pour hot coffee or espresso evenly into two mugs. Add the steamed pumpkin milk mixture on top, allowing the flavors to meld.
06 - Top with whipped cream and a dusting of pumpkin pie spice or cinnamon, if desired. Serve immediately while hot.
