Oatmeal Raisin Cookies

I don't know where I got this recipe. It's in my recipe binder and it says, "the best oatmeal cookie recipe I've found so far. Maybe not oatmeal-y enough but pretty dang good." Apparently whenever I copied it, I was already a reasonably proficient cookie maker, because I didn't write down any directions, assuming I knew how to mix the ingredients.

I may have to make another batch.
