I had the wonderful experience of going to an all-women's Catholic college. The Benedictine sisters fed us very well, and this is the recipe for their famous chocolate chip cookies. It is a soft, shortening-based cookie with a "sinful" amount of chocolate chips. I have been making this recipe for 25 years now, and I've only made a few changes to "modernize" it. For example, I use only non-hydrogenated vegetable shortening with zero trans fat. And I do not mix these by hand anymore. By the time all the chocolate chips go in it is a very stiff dough, so I do it all in my big kitchen-aid standing mixer.
Note: If you cannot find non-hydrogenated shortening at your regular market you'll be able to find it at a natural food store such as Whole Foods.
