1 1/2 C to 2 C ICE cold water-really really cold
1 1/2 C non-fat dry milk powder
2/3 C sugar
1/4 C unsweetened cocoa
2-3 C ice cubes
2 T vegetable oil
Place ALL ingredients into the blender, including the oil. Use less water for a thicker shake, or more for a shake that's easier on your blender motor. With lid on, process for two minutes. Makes about 4 shakes.
