EMACS is a text editor written by Richard Stallman (rms) as the first part of the GNU project. For many years there was a text file in with the distribution with several recipes for cookies. Unfortunately it was removed in 2014 so it is now apocryphal and I include it here. The file itself is here: http://www.soronlin.org.uk/local--files/emacs-cookies/Emacs%20COOKIES.txt
But I will also expound on the first and original recipe in the file which I find makes fantastic cookies and requires a great amount of fun since it makes so many. You need a huge bowl, or even two, and you need to have a production-line process to cook them, which is a great caper. Unlike lesser recipes, you won't eat them all in the first evening either.
