where can i find
Have you checked at Target, Lunds/Byerly's, or Kowalski's? You could probably even do online/mail order if you're desperate - Pillsbury seems to be still making them.
But if you find them, PLEASE don't feed these cookies to children. These cookies contain trans fats - and NO ONE ever eats the 'official' serving size, so those trans fats accumulate alarmingly. Per Pillsbury, the ingredients are:
Enriched Flour Bleached (wheat flour, niacin, iron, thiamin mononitrate, riboflavin, folic acid), Sugar, Partially Hydrogenated Soybean And/or Cottonseed Oil, Water, Peanut Butter (peanuts, dextrose, hydrogenated cottonseed oil, salt), Molasses. Contains 2% or less of: Wheat Protein Isolate, Salt, Baking Soda, Eggs, Artificial Flavor.
