Ingredients

Cookie Dough Layer

  • 16 oz refrigerated chocolate chip cookie dough or make homemade

Brownie Layer

  • 1 18-oz box brownie mix plus ingredients called for on the box, OR the following homemade brownie recipe instead
  • 1/2 cup unsalted butter melted
  • 1 cup granulated sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1/3 cup unsweetened cocoa powder
  • 1/2 cup all-purpose flour
  • 1/4 teaspoon salt

Oreo Cookie Layer

  • 16 Oreo cookies about 6-oz *

Instructions

  • Preheat the oven to 350°F (177°C). Line an 8-inch square baking pan** with parchment paper and set aside.
  • Press the cookie dough into the bottom of the pan using your fingertips. You want an even layer that's about 1/4-inch (1/2 cm) thick.
  • Arrange the Oreo cookies in a single layer of 4x4 on top of the cookie dough. It's fine if there's some wiggle room between the Oreos.
  • Make the brownie batter in a medium bowl according to the package directions (Note: you will only need HALF of the 18-oz box and ingredients called for on the box - the remaining batter can make extra brownies or cupcakes). To make homemade batter, beat the butter and sugar in a medium bowl until fluffy. Then beat in the vanilla and eggs one-by-one. Then stir in the flour, cocoa and salt until combined.
  • Pour the brownie batter evenly across the Oreo cookies (it should be just enough to thinly cover the Oreos). Use a spatula to spread it out to fill the nooks and crannies as needed.
  • Bake for 35-40 minutes or until a toothpick or cake tester inserted in the middle comes out clean. (A shorter duration makes a wetter brownie while a longer duration produces a cakier texture.)
  • Remove from the oven and allow the brownies to cool completely in the pan for at least one hour. This is crucial to prevent the layers from deflating or collapsing.
  • Use the parchment to lift the brownies out of the pan. Use a sharp knife to cut into squares. Serve with chocolate sauce or ice cream if desired.

Notes

  • * Oreo flavors that work well include: Regular, Double Stuf, Chocolate Oreos, Red Velvet and even Golden Oreos. Avoid using exotic flavors like Mint or Lemon.
  • ** A 9-inch square pan also works, although the Oreos don't fit in quite as nicely.
