Ingredients

1 (18-oz.) box brownie mix, plus ingredients called for on box

16 Oreos

4 (1.55-oz.) Hershey’s Cookies ’n’ Creme Bars

Melted chocolate, for drizzling (optional)

Preparation

Step 1Preheat oven to 350° and line a 8"-x-8" pan with parchment paper. Prepare brownie batter according to package instructions. Pour batter into prepared pan, then top with an even layer of Oreos. Press down on Oreos so batter covers them almost completely. Step 2Bake until a toothpick inserted into center comes out mostly clean, about 35 minutes. Let cool completely. Step 3Place unwrapped candy bars in a medium microwave-safe bowl. Microwave in 30-second increments until melted and smooth, stirring well between each increment. Pour over cooled brownie and use an offset spatula to smooth into an even layer. Step 4Refrigerate until set, about 10 minutes. Drizzle with melted chocolate, if using, then slice into squares.
