Did I also mention soy-free? Maybe we should start a thread called "Stump the Chumps" like they have on Car Talk, because I think this might be a stumper !

I think I am close to making up a recipe. I'm finally getting around to making my GF and everything else free cake for my birthday, even though my b-day was a month ago. DH is too overwhelmed by my diet for this task. I made a chocolate cake from a Pamela's mix - excellent! The frosting is now the challenge. I tried making the frosting from the "Enjoy Life" semi-sweet chocolate chip package, but I don't like it. Seems that I need to make my own powdered sugar with a substitute for cornstarch. How do I substitute cornstarch in quantity with arrowroot? This is the recipe I found for making your own powdered sugar. Any suggestions for how to make it corn free, and how to make it a good tasting, fluffy chocolate frosting? To give you an idea how good I'm at baking, I own a copy of "The Idiot's Guide to Baking". Help!

2 cups unbleached cane sugar
1/2 cup cornstarch

Blend in food processor or blender for 1 minute. Scrape down sides & blend an additional 30 seconds.

I'm also thinking of substituting my birch sugar (xylitol not from corn) for the cane sugar. It looks and acts like regular sugar.
