Irresistible brown butter chocolate chip cookie bars are a thick, chewy, and decadent bite of heaven! Made with simple pantry staples like brown sugar, chocolate chips, and pecans along with aromatic brown butter, and a sprinkle of salt at the end to bring it over the top! The entire batch is ready in 40 minutes which is more than the time it takes to devour them all!
Preheat the oven to 350°F and line a 9x9 baking dish with parchment paper. Set aside.
In a medium saucepan over medium heat, add the butter. Melt, stirring every couple minutes, until the butter begins to create brown bits at the bottom of the pan and starts to give off a nutty scent.
Pour the browned butter into a large mixing bowl and set aside to cool for a couple minutes.
To the slightly cooled butter, add the brown sugar and whisk together. Add the vanilla and eggs, whisking again until thoroughly combined.
Add in the flour, cinnamon, and salt. Use a spatula to fold together until a thick batter forms.
Add in all but approximately 2 ounces of the chopped chocolate and a tablespoon of the chopped pecans. Stir to evenly distribute.
Pour the batter into the prepared baking dish and sprinkle the remaining chopped chocolate and pecans evenly across the top.
Bake for 20-25 minutes or until a toothpick inserted into the center comes out cleanly.
Immediately sprinkle with sea salt when removing the bars from the oven. Let cool approximately 20-30 minutes before slicing into bars.
