AHA!

I've been looking for this recipe for a couple of YEARS. I lost it a while back, and now it's been found again. This is the BEST milkshake recipe, and it doesn't use any ice cream...

1-1/2 cups cold water
1-1/2 cups nonfat dried 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 oil to help it stick together

Whiz it in the blender for a couple of minutes. Haven't had them in a very long time, obviously, but I think I'll make it for the kids tomorrow if I can find the ice cube trays! :)
