For the Cookies:

  • 1/2 cup unsalted butter melted
  • 1/3 cup granulated sugar
  • 1/2 cup light brown sugar packed
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 1/2 cups all-purpose flour
  • 1 1/2 cups chocolate chips semi-sweet or milk
  • 24 Oreos any flavor

For the Brownies:

  • 4 ounces unsweetened baking chocolate coarsely chopped
  • 3/4 cup unsalted butter
  • 1 3/4 cups granulated sugar
  • 3 large eggs
  • 1 tablespoon vanilla extract
  • 1/2 teaspoon salt
  • 2 tablespoons unsweetened cocoa powder
  • 1 cup all-purpose flour


  • Preheat oven to 350°. Line a 9x13” pan with foil and spray with cooking spray.
  • Make the cookies: Cream together butter and sugars in the bowl of a stand mixer or in a large bowl using a hand mixer. Mix in egg, extract, baking soda, and salt. Stir in flour, then stir in chocolate chips.
  • Press the cookie dough into the bottom of the prepared pan. Top evenly with Oreos.
  • Make the brownies: Place the baking chocolate and butter in a large, microwave safe bowl. Heat on HIGH power for 2-3 minutes, stirring every 30 seconds, until chocolate is smooth. Stir in sugar. Add eggs, vanilla, and cocoa and stir well. Add flour and stir carefully.
  • Spread brownie batter over the top of the Oreos in prepared pan.
  • Bake for 30-40 minutes until the top looks done and the center is no longer jiggly.



Peanut Butter Cup Slutty Brownies: use regular size peanut butter cups instead of the Oreos.
Use Peanut butter cookie dough or peanut butter chocolate chip cookies instead of the chocolate chip cookies.
