Use this classic cookie dough from Matt Lewis of Brooklyn's Baked bakery to make his Brookie (brownie-cookie) dessert.
In a large bowl, whisk together flour, salt, and baking soda; set aside.
In the bowl of an electric mixer fitted with the paddle attachment, cream together butter and both sugars until smooth and creamy. Using a spatula, scrape down side of bowl; add egg and beat until well combined. Mixture should be light and fluffy. Add vanilla and beat just to incorporate, about 5 seconds.
Add half of the flour mixture and beat until just combined, about 15 seconds. Add remaining flour mixture and beat until just incorporated. Gently fold in chocolate chips.
Cover bowl and refrigerate at least 3 hours before using.
