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!
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.
