The original recipe (5 Ingredient Perfect Chocolate Chip Cookies) I pinched from Baker Bettie's website. The cookies can be made with white, or brown sugar, butter, margarine or lard, any kind of flour and any kind of chocolate chip you have on hand.
Mix butter and sugar together until thoroughly combined.
Add the egg and mix until incorporated.
Stir in flour, the chocolate chips and nuts, if desired.
Scoop onto a cookie sheet lined with parchment (or use a silpat) by the tablespoonsful, place about 2 inches apart - they will spread out some.
Bake at 350° until just lightly browned on the edges (the middle may look a bit undercooked) 7-9 minutes (it may take longer depending on the size of the cookies - if you used a level or heaping tablespoonful - and your oven...it took about 18 minutes in my oven.)
Allow to cool on the baking sheet 2 minutes, then remove to a rack to cool completely.
