Brown Butter Chocolate Chip Cookie Brownie Bars aka Brown Butter Brookies

Preheat the oven to 350°F (175°C). In a saucepan, melt the butter over medium heat until it turns golden brown and gives off a nutty aroma. Remove from heat and let it cool slightly. In a large mixing bowl, combine the brown sugar, granulated sugar, and brown butter. Mix until well combined. Add the eggs and vanilla extract to the mixture and mix until smooth. In a separate bowl, whisk together the all-purpose flour, cocoa powder, baking powder, and salt. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Fold in the chocolate chips. Pour the batter into a greased baking dish and spread it evenly. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs. Remove from the oven and let it cool in the pan for 1 hour before cutting into bars. Enjoy!
