Brown Butter Chocolate Chip Cookie Skillet

0 Preheat your oven to 375°F (190°C).
1 In a medium saucepan, melt the butter over medium heat. Continue cooking, swirling the pan occasionally, until the butter turns golden brown and develops a nutty aroma, about 3-5 minutes. Remove from heat and let it cool slightly.
2 In a mixing bowl, whisk together the flour, baking soda, and salt.
3 In a large mixing bowl, combine the brown sugar, granulated sugar, and browned butter. Mix until well combined and smooth.
4 Beat in the egg, followed by the vanilla extract, until smooth.
5 Gradually add the dry ingredients to the wet ingredients, stirring until just combined. Be careful not to overmix.
6 Gently fold in the chocolate chips until evenly distributed throughout the cookie dough.
7 Pour the cookie dough into the hot skillet, spreading it out evenly.
8 Place the skillet back in the oven and bake for 15-20 minutes, or until the edges are golden brown and the center is set.
