04 - Divide the spiced syrup evenly between two mugs. Add the espresso or brewed coffee to each mug and stir until combined.
05 - Pour steamed milk over the coffee mixture, holding back foam with a spoon, then top with the milk foam.
06 - Garnish with whipped cream, a light dusting of cinnamon or nutmeg, and a mini gingerbread cookie if desired. Serve immediately.
