Last winter I made this and it was AMAZING! But I didn't have vanilla so I subed with peppermint.
1 cup milk
2 pumps peppermint
Heat them up on the stove.
1 cup whip cream
1/2 cup chocolate syrup
1 tbsp cinnamon
Mix then together and stick in the freezer.
Pour milk into mug and take the mix out of the freezer and put it into mug.
Top it with whip cream and sprinkle with cinnamon and some how you end up with a Mexican hot chocolate when you sub peppermint for vanilla.
I would post the link to this but it has a suspicious link alert so I wont be posting the link.
