In a bowl, mix together the spices, sugar and vanilla extract. Heat 100ml of the milk in a pan with the spice and sugar mix, whisking until the sugar has dissolved. Whisk in the remaining milk in additions until incorporated, then heat through until steaming.
Put a shot of espresso in each glass (if using) and top up with the spiced milk. Top with whipped cream, extra spices and a mini gingerbread man.
