What are some good cookie recipes?

Ok so I have a presentation and I have narrowed it down to a cookie recipe. I have five minutes to present it and just have to make the batter. I need the whole recipe to tell the class and it needs to serve at least 30-35 (if it doesn’t feed that much either say to double it or double it when you write it. Thanks so much for your help, I’ve drawn a blank on cookie recipes.
