Step 1: 1) pour milk and cream into a cooking pot. To measure out how much you need for one person, just pour 2/3 of milk and 1/3 of cream into the mug that you will be using.
Step 2: 2) break chocolate into smaller pieces and add to the pot.
Step 3: 3) slowly heat up the milk, cream and chocolate while stirring. You do not want this to boil.
Step 4: 4) when the chocolate is melted, pour the mixture into your mug and add a little cinnamon if you like that.
Step 5: 5) put some whipped cream on top, and done! :d
