Equipment

Ingredients

  • 1 cup unsalted butter melted and then cooled for at least 5 minutes (226g)
  • 1 cup light brown sugar firmly packed (200g)
  • ¾ cup granulated sugar (150g)
  • 2 large eggs + 1 large egg yolk room temperature preferred
  • 1 ½ teaspoons vanilla extract
  • 2 ¼ cups all-purpose flour (285g)
  • 2 teaspoons cornstarch (cornflour in the UK)
  • ½ teaspoon baking powder
  • 1 teaspoon salt
  • 2 cups semisweet chocolate chips (340g)

Instructions

  • Preheat oven to 350F (175C) and prepare a 9x9" (23x23cm) pan by lining with parchment paper (or lightly grease and flour).
  • Combine melted (cooled) butter and sugars in a large bowl, stir well.
  • Add eggs, egg yolk, and vanilla extract and stir until well-combined.
  • In a separate, medium-sized bowl, whisk together flour, cornstarch, baking powder, and salt.
  • Gradually stir dry ingredients into wet until completely combined. Stir in chocolate chips.
  • Spread batter evenly into prepared pan. Bake on 350F (175C) for 35 minutes or until edges just begin to turn golden brown.
  • Allow to cool before cutting and serving (don't cool too long, though -- these are amazing when served still slightly warm!)
