Ingredients
  

For the cookie bars
  • 1 cup salted butter plus 2 tbsp (total of 254 grams)
  • 3/4 cup brown sugar, packed (163 grams)
  • 3/4 cup granulated sugar (155 grams)
  • 2 tsp vanilla extract
  • 2 large eggs
  • 2 2/3 cups all-purpose flour spooned & leveled or weighed out (347 grams)
  • 1 tsp baking soda
  • 1/4 tsp salt
  • 1 1/2 cups semi-sweet chocolate chips plus a generous handful for topping
  • to taste flaky sea salt for topping

Method
 

Make the Brown Butter
  1. Melt the butter in a medium saucepan over medium heat, stirring occasionally.
  2. Lower the heat to medium-low and keep stirring until the butter foams and becomes a deep golden hue, about 4-6 minutes.
  3. Pour the browned butter into a mixing bowl and let it chill in the freezer for about 30 minutes.
Prep
  1. Preheat your oven to 350°F (175°C).
  2. Grease a 9x13 pan with nonstick spray and line it with parchment paper.
Make the Cookie Dough
  1. Cream the brown butter in a large mixing bowl using an electric mixer on high speed.
  2. Add the brown and granulated sugars and mix on high for about 1 minute.
  3. Pour in the vanilla extract and add the eggs, mixing until just incorporated.
Add the Dry Ingredients
  1. Gently fold in the flour, baking soda, and salt until a dough forms.
  2. Toss in the semi-sweet chocolate chips, mixing them evenly through the dough.
Bake
  1. Spread the dough evenly into the prepared pan, adding extra chocolate chips on top.
  2. Bake for 14-16 minutes or until the edges are golden and the center is still slightly soft.
Serve + Store
  1. Let the cookie bars rest on the counter for about 30 minutes before slicing.
  2. Store leftovers in an airtight container for 4-6 days.

Notes

For extra flavor, consider adding chopped nuts or drizzling caramel on top. If using unsalted butter, add a pinch of salt for balance.
