Chocolate goes well with both bananas and milk, so we decided to combine three ingredients in one drink - and we did not lose. Try it!
Peel banana and cut into slices. Finely chop or grate the chocolate. Pour milk into a saucepan, add bananas and chocolate. Place over medium heat and, stirring constantly, bring to a boil.
Beat in a mixer until foam appears, pour into cups, putting cinnamon in each.
