Ingredients

Scale
  • 1 cup (227 g) unsalted butter, browned
  • 3/4 cup (150 g) light brown sugar
  • 1/4 cup (50 g) granulated sugar
  • 2 large eggs, room temperature
  • 1 1/2 teaspoons pure vanilla extract
  • 2 cups (240 g) all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon fine sea salt
  • 1 1/2 cups (270 g) chocolate chips (semi-sweet or mix of semi-sweet and dark)
  • Optional: 1/2 cup (60 g) chopped walnuts or pecans

Instructions

  1. Brown the butter: Place 1 cup (227 g) unsalted butter in a medium saucepan over medium heat. Stir frequently until it foams, turns golden brown, and smells nutty (about 5-7 minutes). Remove from heat and let cool slightly.
  2. Combine sugars and eggs: In a large bowl, whisk together 3/4 cup light brown sugar and 1/4 cup granulated sugar. Add the slightly cooled brown butter and mix well. Beat in 2 large eggs one at a time, then stir in 1 1/2 teaspoons pure vanilla extract.
  3. Mix dry ingredients: In a separate bowl, sift together 2 cups all-purpose flour, 1 teaspoon baking soda, and 1/2 teaspoon fine sea salt.
  4. Combine wet and dry ingredients: Gradually fold the dry ingredients into the wet mixture using a rubber spatula. Stop mixing as soon as combined to avoid overmixing.
  5. Fold in chocolate chips and nuts (if using): Gently stir in 1 1/2 cups chocolate chips and 1/2 cup chopped nuts if desired.
  6. Prepare pan and bake: Grease or line a 9×13-inch baking pan with parchment paper. Spread the dough evenly in the pan and smooth the top. Bake at 350°F (175°C) for 25-30 minutes, or until edges are golden brown and a toothpick inserted near the center comes out with a few moist crumbs.
  7. Cool and cut: Allow bars to cool completely on a cooling rack for at least 30 minutes before cutting into squares and serving.

Notes

Brown the butter carefully to avoid burning; stir frequently and watch for a nutty aroma. Do not overmix the dough once flour is added to keep bars chewy, not cakey. Let bars cool completely before cutting to maintain shape. Tent with foil if bars brown too quickly on top. Chilling dough for 15 minutes before baking helps flavor and spreading.
