6 C. double-strength freshly-brewed dark roast coffee
2/3 C. unsweetened cocoa powder, plus additional for garnish
2 C. nonfat milk
Fill ice cube trays with half of the brewed coffee and place in the freezer.
In a bowl, combine the remaining brewed coffee, cocoa powder and milk and stir to
dissolve the cocoa. Cover and chill.
When the ice cubes have frozen, transfer them to a kitchen towel and, using a
hammer or mallet, crush the cubes. Fill 4 glasses with the crushed ice and divide
the coffee-cocoa mixture evenly among them. Dust the top with cocoa powder
and serve.
