This brownie batter Oreo cookie recipe embraces the chocolatey-brownie flavor of the cookie for a double-chocolate brownie with an added cookie crunch.
Heat the oven to 350 degrees F. Lightly butter a 9-by-13-inch pan and set aside. In a medium bowl or the bowl of a stand mixer, combine the butter, brown sugar, granulated sugar, vanilla extract, and eggs. Beat on medium for about a minute until combined. Then, add the salt and cocoa powder and mix until incorporated; about another minute. Then, add the flour in 3 additions, beating after each addition to incorporate. Stir in the chocolate chips, if using. Pour half of the batter into the prepared pan. Then, sprinkle with the crushed Oreos and top with the remaining batter. Bake for 35 to 40 minutes or until the brownies are cooked through and a toothpick comes out clean. Enjoy.
