Betsy - unfortunately what follows does not answer your request BUT a) it is good and easy and b) I sure hope someone come's up with the Dunkin' Donut Coolatta recipe. Anyway, several years ago at the New York Gift Show I paid for a coffee/chocolate drink that I think I've figured out. I place 1 teaspoon of Maxwell House INSTANT coffee granules in the bottom of a 16-oz glass and add just enough hot water to dissolve it. Then I add Hershey's chocolate syrup to taste and fill the glass about 2/3 full with cold water. Finally, I stir and fill to the top with ice cubes. See what you think! This is the only way that I drink coffee but REAL coffee drinkers would probably prefer using brewed coffee and they could even use coffee ice cubes! judi in Delaware
