Mix the cocoa powder and sugar in a saucepan. Stir in enough coffee to make a paste, then add the rest of the coffee. Heat just to boiling, stirring frequently.
Cool slightly, add mint flavoring, then pour into ice cube trays or a shallow dish or pan. Freeze until almost solid.
Place frozen coffee mixture into a blender or food processor. Add milk and process until smooth.
Transfer to a serving glass and top with a sprig of fresh mint.
For a fancy desert, add a scoop of vanilla or chocolate ice cream to the mix.
Mr Breakfast would like to thank football for this recipe.
