Ingredients

Scale
  • 1 cup (227g) unsalted butter, browned and cooled slightly
  • 1 cup (200g) light brown sugar, packed
  • ½ cup (100g) granulated sugar
  • 2 large eggs, at room temperature
  • 2 teaspoons pure vanilla extract
  • 2 ½ cups (312g) all-purpose flour
  • 1 teaspoon baking soda
  • 1 teaspoon salt
  • 2 cups (340g) chocolate chips, semi-sweet or a mix of semi-sweet and dark
  • Optional: 1 cup chopped walnuts or pecans

Instructions

  1. In a medium saucepan over medium heat, melt 1 cup (227g) unsalted butter. Stir constantly as it foams and then turns golden brown with a nutty aroma, about 5-7 minutes. Remove from heat and pour into a large mixing bowl to cool for 5 minutes.
  2. Add 1 cup (200g) light brown sugar and ½ cup (100g) granulated sugar to the browned butter. Stir until smooth and combined.
  3. Crack in 2 large eggs (room temperature) one at a time, whisking after each addition. Stir in 2 teaspoons pure vanilla extract until the mixture is shiny and smooth.
  4. In a separate bowl, whisk together 2 ½ cups (312g) all-purpose flour, 1 teaspoon baking soda, and 1 teaspoon salt.
  5. Gradually add the dry ingredients to the wet mixture, stirring gently until just combined. Stop when no more flour streaks are visible to avoid overmixing.
  6. Fold in 2 cups (340g) chocolate chips and, if using, 1 cup chopped nuts.
  7. Spread the batter evenly into a greased or parchment-lined 9×13 inch baking pan.
  8. Bake in a preheated 350°F (175°C) oven for 25-30 minutes. Check doneness by inserting a toothpick in the center; it should come out with a few moist crumbs but no raw batter.
  9. Let the bars cool completely on a wire rack before cutting into squares.

Notes

Watch the butter closely when browning to avoid burning. Use room temperature eggs for better texture. Do not overmix the dough to keep bars tender. Line the pan with parchment paper for easier cleanup and removal. Let bars cool completely before cutting to prevent crumbling. For gooier bars, reduce baking time by 1-2 minutes.
