Just Like a Frosty

from the Hillbilly Housewife

1-1/2 to 2 cups ice water

1-1/2 cups nonfat dry milk powder

2/3 cup sugar

1/4 cup unsweetened cocoa

1 teaspoon vanilla

1 to 1-1/2 trays of ice cubes

2 tablespoons corn oil plus a 5-second squirt of Pam (or 1/2 tsp lecithin) 

Place all of the ingredients into the blender, including the oil and the non-stick spray/lecithin. Use less water for thicker milk shakes and more water for shakes that are easy on your blender motor. The blender should be about 3/4's full. Place the lid on. Process for a full 2 minutes. Pour into cups and serve. Makes 4 - 12oz servings.
