Instructions

  1. Step 1: Preheat oven to 350°F and line an 8x8-inch baking pan with parchment paper, leaving overhang for easy removal. In a medium saucepan, melt 6 tbsp unsalted butter over medium heat, stirring frequently until it foams and turns golden brown with a nutty aroma, about 5 minutes; immediately remove from heat.
  2. Step 2: Transfer the brown butter to a large mixing bowl and whisk in 3/4 cup light brown sugar and 1/4 cup granulated sugar until combined. Add 1 large egg and 1 tsp vanilla extract, whisking until smooth.
  3. Step 3: Stir in 1 cup all-purpose flour, 1/2 tsp baking soda, and 1/4 tsp salt until just combined. Fold in 3/4 cup semisweet chocolate chips evenly.
  4. Step 4: Spread the batter evenly into the prepared pan with a spatula and bake for 22-25 minutes until golden brown on the edges and a toothpick inserted in the center comes out with a few moist crumbs.
  5. Step 5: Remove from oven and cool completely in the pan on a wire rack before slicing into bars.
