Help with peanut chicken recipe....?

out of all the chinese places we have eaten at, only 2 have peanut chicken, and only one of them is good enough to go back. I really love peanut chicken, and would love to make it at home, but....i need peanut flour....i really dont want to order it online, does anyone know a place i could go buy peanut flour in Indiana? I live between indy and columbus.
