I've never done this before but have you ever tried grinding your own nuts to make a 'nut butter' type of peanut butter? This is what I've heard, you go to the whole foods place, get your nuts and then i'm assume it...blends them? grinds them? whatever you want to call it, I'm not too informed lol but i'm sure if you look into it you'll find more info
Yes I have done that before at my local health food store. The reason I was wanting to try the powdered peanut butter, however is because it is "de-fatted" during the deydration process making it less fat than even natural peanut butter.
