My caveat: if there is oatmeal in the recipe, freezing can change...
...the consistency of the baked cookie somewhat.
My favorite recipe has oatmeal, and if I freeze it, or, for that matter, let it sit in the fridge for more than a few hours, the oatmeal tends to soak up some of the wet ingredients and the resulting cookie has a slightly chewier texture than I prefer.
Slight, but detectable.
