Step 1In a blender, blend the espresso or coffee with the chocolate. Strain.
Step 2Pour the liqueurs into each of two (8-ounce) coffee mugs. Heat the chocolate-coffee blend in a steamer or a saucepan and divide it between the mugs.
Step 3Fill each mug to the brim with steamed milk. Garnish each mug with equal amounts of cinnamon and sugar, a pinch of rice cracker balls, if using, and a cinnamon stick.
