1/3 cup finely ground espresso-roast coffee or other dark-roast coffee
3/4 cup vanilla nonfat frozen yogurt
1/2 cup ice cubes
1 1/2 tablespoons sugar
Put coffee grounds in a paper-lined coffee filter set over a mug. Pour 1 cup hot (190*F) water into filter and let drip through. Chill until cool, about 20 minutes.
In a blender, whirl coffee, frozen yogurt, ice cubes, and sugar until smoothly pureed. Pour into a glass.
