Iced Mocha Frappe
In a heat-proof bowl or pitcher, add the coffee, hot chocolate mix, and sugar. Stir until well combined. Pour the mixture into ice cube trays and freeze, covered, for at least 3 hours and up to 1 week.
Put the frozen cubes in a blender. Add the cream and vanilla and puree until smooth. Divide the frappe into tall glasses and top with whipped cream.
