Make the browned butter: place the 1 cup butter into a 12 inch cast iron skillet over medium heat. Melt the butter and bring to a simmer, cook and stir until the butter becomes foamy, continue stirring until the butter is browned and smells like caramel. Remove from the heat, allow to cool, until it is just warm to the touch.
Make the cookie dough: add the 3/4 cup brown sugar, 1/2 cup sugar, and 1 1/2 teaspoons vanilla and mix with the browned butter until combined. Then, add in the 1 cup pecans and 1 egg, mix well.
Add the dry ingredients: stir in the 2 1/4 cups all purpose flour, 1 teaspoon coarse sea salt, 1/2 teaspoon baking soda, and 1/2 teaspoon baking powder until a soft cookie dough is formed. Fold in the 1 1/2 cups semi-sweet chocolate chips until incorporated in the dough.
Bake: bake for 22-25 minutes, until the edges are golden brown and the center is not jiggling.
