Preheat oven to 350. Cream two sticks softened butter with a cup of granulated sugar and a half cup light brown sugar until well-blended. Beat in 2 large eggs and a tablespoon vanilla extract. Separately, add a teaspoon baking soda and a teaspoon salt to 2 ½ cups flour, blend into the butter/eggs, along with 2 cups chocolate chips to make a dough. Line a 9×13 baking dish with foil, coat generously with cooking spray, and mash the cookie dough onto it. Add a layer of Double Stuffed Oreos. Top with a brownie batter made with a family size box of good brownie mix. Cover with foil and bake for 30 minutes. Remove foil and continue baking for an additional 15-25 minutes. Cool completely before cutting. And yes, slackers, you can use store-bought chocolate cookie dough. But it won’t be as good.
