For the Cookies:

  • ½ cup (113g) unsalted butter melted
  • cup (57g) granulated sugar
  • ½ cup (100g) light brown sugar packed
  • 1 large egg
  • 1 teaspoon vanilla extract
  • ½ teaspoon baking soda
  • ½ teaspoon salt
  • 1 ½ cups (186g) all-purpose flour
  • 1 ½ cups (255g) chocolate chips semi-sweet or milk
  • 24 Oreos any flavor

For the Brownies:

  • 4 ounces (113g) unsweetened baking chocolate coarsely chopped
  • ¾ cup (170g) unsalted butter
  • 1 ¾ cups (350g) granulated sugar
  • 3 large eggs
  • 1 teaspoon vanilla extract
  • ½ teaspoon salt
  • 2 tablespoons (10g) unsweetened cocoa powder
  • 1 cup (124g) 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.



  • You're going to want a 9x13-inch pan for this recipe, one with 2" sides. Use metal or glass, whichever you prefer.
  • You can also make these in muffin tins if you want Oreo Cookie Brownie Cupcakes!
  • I like to cover the pan with foil and spray with nonstick cooking spray to make removal and slicing easier.
  • First, press the chocolate chip cookie dough into the bottom of the pan.
  • I used regular Oreos but you could use double stuff or any flavor you want.
  • 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.
