Brown Butter Chocolate Chip Cookie Bars

Preheat oven to 350 degrees F. Grease a 9×13-inch metal baking pan with nonstick cooking spray. You can line the pan with parchment paper, if desired. Set aside.

Place the butter in a medium saucepan and melt over medium heat, stirring often, until it foams, smells nutty, and browns. This will take about 5 minutes. Scrape the browned butter into a large mixing bowl and let cool for 5 minutes.

Add the brown sugar and granulated sugar to the brown butter and stir with a wooden spoon or spatula until smooth. Add the eggs and vanilla. Stir until combined.

Add the flour, salt, baking soda, and baking powder. Stir until just combined, don’t over mix.

Stir in the chocolate chunks and chocolate chips.

Spread the dough evenly in the prepared pan with a spatula. Bake for 18 to 24 minutes or until the bars are set and golden brown. Don’t over bake the bars will continue setting up as they cool.

Remove from the oven and sprinkle with flaky sea salt. Let the bars cool before cutting into squares.
