Ingredients
  

Dry Ingredients

  • 2.5 cups all-purpose flour
  • 1 teaspoon baking soda
  • 1 teaspoon corn starch
  • 0.5 teaspoon kosher salt

Wet Ingredients

  • 1 cup unsalted butter room temperature, 2 sticks
  • 1 cup brown sugar
  • 0.5 cup granulated sugar
  • 2 large eggs room temperature
  • 2 teaspoons pure vanilla extract

Chocolate Chips

  • 1.5 cups semisweet chocolate chips divided

Instructions
 

Preparation

  • Preheat your oven to 350°F. Line an 8×8-inch baking pan with parchment paper and spray it with nonstick spray. Set aside.
  • In a medium bowl, whisk together the flour, baking soda, corn starch, and salt.
  • In a stand mixer fitted with the paddle attachment, add the butter, brown sugar, and granulated sugar. Beat until light and fluffy, about 1-2 minutes. Scrape down the sides of the bowl as needed.
  • Add the eggs and vanilla extract, mixing until well combined, about 1 minute.
  • Gradually mix the dry ingredients into the wet ingredients until just combined.
  • Gently fold in 1 cup of the chocolate chips.
  • Transfer the cookie dough to the prepared pan and spread into an even layer.
  • Sprinkle the remaining ½ cup of chocolate chips evenly over the top.

Baking

  • Bake in the preheated oven for 15 minutes.
  • Loosely cover with aluminum foil and bake for an additional 35 minutes, or until edges are set and the middle is slightly browned.
  • A toothpick inserted in the center should come out clean.
  • Let the cookie bars cool completely in the pan before removing and slicing into 16 squares.

Notes

Make sure your butter is at room temperature for easy mixing. Don't overmix the dough. You can experiment with different types of chocolate chips or nuts. Let the bars cool completely before cutting for the cleanest slices.
