Brown Butter Chocolate Chip Cookie Bars

Tracy @ Next Level Baker
Brown butter chocolate chip cookie bars are chewy, rich, and full of nutty flavor. The browned butter deepens the taste of this sweet classic, while crisp edges and a soft center surround melty pockets of chocolate in every bite.

Equipment

  • 1 Stand or hand mixer optional

Ingredients
  

  • 18 tablespoons butter (2 sticks plus 2 tablespoons) browned
  • 1 ½ cup brown sugar
  • ½ cup white sugar
  • 2 eggs
  • 2 teaspoons vanilla
  • 2 ½ cups all-purpose flour (300 grams)
  • 1 teaspoon baking powder
  • 1 teaspoon salt
  • 10 ounces chocolate chips or chunks

Instructions
 

  • Brown the butter. Cut the butter into smaller pieces and heat over medium to medium low heat for 5-8 minutes. As the butter starts to melt, stir occasionally so that it melts evenly. After the butter has melted, it will start to foam. Once it starts foaming, the milk solid will separate. Stir more frequently so that you can see the color of the milk solids. Once the solids start to brown, stir even more frequently, almost constantly, until the solids are a golden brown. When the milk solids are a golden brown, it will also give off a nutty aroma. Once the milk solids are golden brown, remove the pan from the heat and carefully add the brown butter to a mixing bowl and allow to cool to room temperature.
  • Preheat the oven to 325℉. Line a 9x13 baking pan with parchment paper.
  • Add the all-purpose flour, baking powder and salt to a small bowl and set aside.
  • Once the brown butter has cooled in the mixing bowl, add the brown sugar and white sugar and mix on low to medium until integrated and smooth.
  • Add the vanilla and eggs and mix until they are fully incorporated.
  • Add half of the flour mixture and mix just until incorporated. Scrape down the sides and add the other half of the flour mixture. Mix until incorporated.
  • Fold in the chocolate chips with a spatula.
  • Add the batter to the baking pan and smooth out with a spatula.
  • Bake for 30 to 35 minutes until the edges are golden brown. Check at 30 minutes.
