Homemade Frappe Mix
                Ingredients
                            1/2 c instant coffee (adjust to taste) (don't do caffeine? use decaf!)
                1 cup sugar
                1 cup non-fat dry milk powder (one package)
                1 cup powdered non-dairy creamer
                1/3 cup baking cocoa (adjust to taste)
                1/4 teaspoon salt
           
        
                    Instructions
                            Mix all ingredients together well (I like to dump them all in my food processor to mix well).
                If you like a stronger/weaker coffee or mocha flavor, adjust those two ingredients accordingly.
                Stores perfectly in a 1 quart jar for up to a year.
           
        
                    To make a perfect frappe/iced capp.
                            1 1/2 cup crushed ice + 1/3 cup mocha mix + 1/4 cup water + 1/4 cup milk = Bliss
                I  like to toss my crushed ice into my food processor first and blend  until it looks a bit like snow, add mix & water, process until well  blended and then add in my milk. I blend just until it's mixed (7-10  seconds).
