Double Chocolate Cookie Bars

Brooke Homec
These double chocolate cookie bars are a chocolate cookie bar loaded with chocolate chips and topped with some flaky salt. They're chewy, chocolatey and so easy to whip up!

Ingredients
 

  • cups (175 g) all-purpose flour
  • ¼ cup (21.5 g) dark cocoa powder
  • 1 teaspoon cornstarch
  • ½ teaspoon (0.5 teaspoon) baking soda
  • ½ teaspoon (0.5 teaspoon) salt
  • ½ cup (113.5 g) salted butter melted and cooled
  • ¼ cups (50 g) granulated sugar
  • ¾ cup (165 g) brown sugar
  • 1 large egg room temp
  • 1 large egg yolk
  • 2 teaspoon vanilla
  • 1 cup (180 g) semi-sweet chocolate chips
  • flaked salt for topping

Instructions
 

  • Preheat oven to 325F. Spray and line an 8x8 baking pan with cooking spray and parchment paper. Set aside.
  • In a medium bowl whisk together flour, cocoa powder, cornstarch, baking soda and salt. Set aside.
  • In another medium mixing bowl whisk together butter and sugars until combined. Add egg, egg yolk and vanilla and mix together.
  • Slowly add dry ingredients until just mixed together. Do not over mix dry ingredients.
  • Fold in the chocolate chips.
  • Spread cookie dough into prepared baking pan. Top with extra chocolate chips.
  • Bake for 23-27 minutes, or until edges look cooked and firm. Sprinkle with flaked salt.

Notes

These cookies bars are also really good with peanut butter chips, m&m's or white chocolate chips in addition to or replacing the chocolate chips.
I have given both cups and grams as measurements. Grams will be more precise, especially when measuring flour. If you don’t have a kitchen scale, no problem! Just lightly spoon flour into your measuring cup to insure its not packed in there. Light and fluffy is the key.
