Break the chocolate into smaller pieces and divide over the four cups. Heat the milk and whisk it well until it foams up.
Pour the hot milk over the chocolate and make sure to add some foam to each cup. Or use whipping cream. Optionally add a bit of cinnamon.
Make the marshmallow men by using two marshmallows for each puppet. Give it arms by using one salty stick and break it in two. Do the same for the leggs. Use a little piece as a neck.
Draw with the edible ink eyes or use it to stick the sugar eyes on. Make a little nose and a mouth and draw some buttons. Place the marshmallow men carefully inside the hot chocolate. Serve right away.
