(Optional to brown the butter on the stovetop then let it cool before making these cookies — this could add a nice caramel flavor if you aren’t using Lyles.) In a mixing bowl, mix together the softened butter, sugar, and Lyles to a smooth paste. Then stir in the egg, vanilla, and salt.
Add the flour and baking soda and mix to combine.
Add in chocolate and extras as desired. Shape into oblong balls. Freeze or refrigerate these for about 12 hours. I think they will spread too much if you don’t chill them, but of course you can also just make them on the spot. We all understand last-minute desires.
Bake with the oblong shape pointing upwards at 350˚F for ~13 min. Take out the pan and tap it hard on a surface so that the centers deflate. Let cool slightly on pan before transferring to rack. Best and chewiest straight out of the oven
