The only time I've ever heard of adding butter is when a child is in dire need of additional calories. Otherwise, why add something not very nutritious to something already not very nutritious?
They're okay though....I've eaten my fair share of them in my younger/college/"can't afford real food" days....I've also bought them for my own children from time to time as a treat.
Oh and just in case anyone wants to know..... the peanut butter ones are like peanut butter cookies.
