How fast can the cookie monster eat all of the cookies, if he must follow some simple rules?

The Cookie Monster is presented with some jars with various numbers of cookies, and he wants to each them as fast as he can. But he only gets to take cookies from one or more jars once per minute. Also, if he takes cookies from more than one jar at a time, he has to take the same number from each. For instance, if he has jars with 1, 2, 3, and 5 cookies, he might choose to take 2 cookies, he might choose to take them from the jars with 2 and 5. After he takes and eats those cookies, the jars have 1, 0, 3, and 3 cookies.
