melt butter in a saucepan, stirring constantly until butter is amber in color and has small brown specs (6-7 minutes).
in a bowl, mix the brown and granulated sugar, egg, egg yolk and add the melted brown butter and combine until all ingredients are incorporated
in another bowl combine the salt, flour and baking soda
Add half of the flour mixture into the butter mixture and stir until completely mixed. Then add the other half until the dough is formed.
Fold in the chocolate chunks or chocolate chips and cover the bowl with wrap. Let it sit in the fridge for 20 minutes.
Preheat the over at 330 Fahrenheit. Scoop the cookie dough into sheet pans and make sure to leave enough space in between. I usually fit 6 dough balls into each cookie sheet.
Bake in the oven for 12 minutes. Take them out and let them sit in the cookie sheet for 5-10 minutes.
