Cold rinse small moulds (espresso cups or larger egg cups; 75 ml capacity each) and line with cling film. Chop chocolate and melt over a warm water bath. Add coconut oil and melt as well. Warm the cream, pour into the chocolate and stir vigorously (caution: it draws quickly). Pour the mixture into the moulds.
Put one cinnamon stick in the middle of each mould. Place in the refrigerator for at least 2 hours. Remove the foil. Mix cocoa, cinnamon and icing sugar and dust the chocolate lollipops with it all around. Place the chocolate lollipops in a cup with hot milk and dissolve in it
