Instructions

1. Brown 1 stick plus 1 tablespoon of butter. Once butter is browned, remove from heat and pour into a bowl to cool slightly.
2. In a stand mixture fitted with the paddle attachment, cream together the other stick of butter with the granulated sugar until creamy, about 3 minutes. Add the vanilla and molasses and beat until incorporated. Add the slightly cooled brown butter and the brown sugar and mix on medium speed for about 2 minutes. Add the egg and egg yolk and mix until fully incorporated. 
3. In a medium bowl, whisk together the flour, salt, and baking soda. Add all at once to the butter mixture and mix on low until just incorporated. Fold in the chocolate chips with a wooden spoon or spatula.
4. Cover bowl with plastic wrap and refrigerate for 30 minutes. Preheat the oven to 375°F. Line two cookie sheets with parchment paper. Scoop dough into balls using a small cookie scoop and place 2 inches apart on baking sheet.
5. Bake for 10-12 minutes until lightly browned.
