In a small pot, add pumpkin puree, milk of choice, spices and sweetened condensed milk for sweetness. Mix with a whisk to combine. Cook over low to medium heat until steaming.
In the meanwhile, prepare espresso any way you prefer.
Take pumpkin milk off the heat. Froth using your favorite method or just stir with a whisk.
Pour frothed milk over the espresso. Garnish with whipped cream and a dash of cinnamon to make it extra special.
