I'm pretty sure most of the organic powdered sugars don't have cornstarch in them.

I make a buttercream type frosting and whip it extra long with my Kitchen Aid and it comes out pretty fluffy. I usually use real butter, but ghee would work fine or you could sub the palm shortening if you wanted. I use almond or rice milk in it and cocoa and powdered sugar. It's quite yummy and easy. (But don't ask for a recipe because I just throw stuff in there until it's the right consistency--then I end up with extra frosting sometimes, but hey, that's not a problem!)

I was quite disappointed to discover today that the 3 or 4 brands of organic powdered sugars I looked at (2 different stores) all had cornstarch in them (at least it was organic cornstarch). I found one brand of cornstarch free powdered sugar on-line, but who has the patience to order that when a chocolate craving is calling !

Well, I *know* I've bought some that didn't but I have 2 different brands in my pantry right now and they both have it in them. I'm sorry!

That's the pits.

I would just try to sub another starch (arrowroot, tapioca) for the cornstarch and try that recipe you posted. Also, if you're just going to use it right away, your probably don't even need the starch--as far as I understand it, that's just to keep it from clumping and if you use it right away it won't clump anyway.

Happy Belated Birthday!
