I am a ex high school cafeteria manager so may I suggest to you that you use the toll house cookie recipe found on the back of the chocolate chip package and REAL BUTTER. I really think it was the commidity butter that gave everything that special flavor in the school cafeterias. The toll house cookie recipe is basically what we used but on a larger scale as all our recipes were per 100 servings. If you call your local cafeteria, you will get a recipe for 100!
