This recipe is baised on one which appears as a footnote in Cliff Stoll's book "The Cookoo's Egg". Some of the measurements were clarified via email a long time ago.
Mix eggs, sugar and melted butter, fold in flour, salt, baking soda vanilla, cocoa & chocolate chips. Place teaspoon sized pieces of the mixture on a baking sheet and cook at 200° C for about 10 minutes.
