Search for the Perfect Frosting: Part 2

So I've been doing some research and I came across this lovely recipe for homemade powdered sugar. Which, essentially is perfect for my cause.

So, instead of using the corn starch the recipe calls for I plan on substituting arrowroot starch.

I am still searching for what kind of frosting I want to make. I'm debating between a tradition "buttercream" or a chocolate "cream cheese" frosting. Maybe I'll make both - who knows.

I will keep you posted as to how the frosting turns out taste and texture wise. Wish me luck on my powdered sugar endeavor!
