Ingredients

The following ingredients have 12 Servings
  • 2 1/4 cups plus 2 tablespoons all purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt (omit if using salted butter)
  • 2 sticks unsalted butter (softened)
  • 1 cup light brown sugar (packed)
  • 1/2 cup granulated sugar
  • 2 large eggs (room temperature)
  • 2 teaspoons vanilla extract
  • 1 cup dark chocolate chunks (reserving 3 tablespoons to press into the top)
  • 1 teaspoon flaky sea salt (I use [Maldon])

Instruction

  • Preheat the oven to 350 degrees. In a medium bowl, whisk together the flour, baking soda and salt. Set aside.
  • In a large bowl, beat the butter and sugars with a hand mixer at low speed until incorporated, then at medium high speed until light and fluffy, about 1 minute. Beat in the eggs and vanilla at low speed until combined.
  • Add the dry ingredients to the wet ingredients and beat on low speed until just combined.  Fold in all but 3 tablespoons of the chocolate chunks.
  • Spoon the batter into a cast iron skillet and spread until smooth, then press the remaining chocolate chunks into the top.
  • Bake for 20-30 minutes or until the top is golden brown and the middle is just set.  If the top begins to brown too quickly, cover loosely with aluminum foil.
  • Remove from the oven and immediately sprinkle with the flaky sea salt. Cool completely on a wire rack or until set, then slice and serve!
