First, add the peppermint extract and chocolate syrup to your mug. I like to add most to the bottom, as it will mix with the hot espresso. But I will also drizzle some up the sides of the mug as well. If you are using a packet of hot chocolate mix instead, you can mix this with the hot milk.
Next, make your espresso. Pour the espresso shot into the prepared mug.
Next, steam the milk. You want the milk hot and to create some foam on top. If your espresso machine has a frothing wand, you can do this all in one step. If not, you may need to heat the milk then froth by hand or use a milk frother. Add the hot chocolate mix during this step to incorporate well if using.
Pour the hot milk into the espresso; the foam will naturally settle on top.
Top with whipped cream, chocolate syrup and other garnishes.
Notes
I also like to garnish this with a mini candy cane or crushed candy canes. Peppermint bark would be a nice addition too.You can use whole milk or any percentage; also, alternative milks will work well here too.
