Sugar Free Powdered "Sugar"

I found this on Recipezaar.com and was so excited!! Sugar Free Powdered "Sugar" Makes 3-4 cups 2 cups nonfat dry milk powder 2 cups cornstarch 1 cup Splenda granular Combine all ingredients in food processor or blender. Blend until well blended and powdered.

At first, this really caught my attention. But then I wondered how 2 cups of corn starch could result in a low-carb alternative to powdered sugar.

I understand that I may be totally missing something! Thanks for posting the recipe. I don't keep powdered sugar around but I do keep corn starch around, so it is great to have an alternative to powdered sugar! Kathy

The recipe is meant as a sugar-free substitute and NOT low-carb. The benefit to me is that when/if I need powdered sugar I not have a sugar-free substitute.
