Ingredients

COOKIE BASE:

  • 1 cup unsalted butter, softened (2 sticks)
  • 1 cup granulated sugar
  • 1 teaspoon pure vanilla extract
  • 1 large egg
  • 3 cups all-purpose flour
  • 1 ½ teaspoons baking powder
  • 12 Oreo cookies, crushed (see note)

CREAM CHEESE LAYER:

  • 8 ounces cream cheese, softened (reduced fat will work, not fat free)
  • ¼ cup unsalted butter, softened
  • 1 teaspoon pure vanilla extract
  • 4 cups powdered sugar

TOPPING:

  • 12 Oreo cookies, roughly crushed

Instructions

  • Preheat oven to 350ºF. Spray 9 x 13-inch baking with nonstick baking spray. Line with parchment paper, and spray parchment with nonstick baking spray
  • In large mixing bowl, cream together butter and sugar using an electric mixer. Add vanilla extract and egg; mix well.
    1 cup unsalted butter, softened, 1 cup granulated sugar, 1 teaspoon pure vanilla extract, 1 large egg
  • Add flour and baking powder and mix well until the dry ingredients are completely incorporated. Dough will be quite stiff so you may have to do this by hand unless you have a powerful hand mixer.
    3 cups all-purpose flour, 1 ½ teaspoons baking powder
  • Stir in crushed Oreos by hand until mostly incorporated.

  • Add dough to prepared pan and, using fingers, pat into an even layer. Bake for 20 minutes or until just golden around the edges and set in the middle. Let cool completely in pan.
  • Once cooled, prepare frosting. In a large mixing bowl, blend cream cheese, butter, and vanilla with electric mixer until creamy. Add powdered sugar, beating well.
    8 ounces cream cheese, softened, ¼ cup unsalted butter, softened, 1 teaspoon pure vanilla extract, 4 cups powdered sugar
  • Spread frosting evenly over cooled cookie bars. Top with crushed Oreo cookies.

  • Cut into desired size pieces. Serve immediately or store in refrigerator.

Notes

  • To crush Oreos: Place the cookies in a gallon-size resealable bag. Seal the top, pressing out excess air, and crush the cookies using a rolling pin, mallet, or heavy can. 
  • Storage/freezing: Store in fridge in a tightly covered container for up to 5 days. The texture of the cookies will get a bit softer. To freeze, store cut bars in a freezer container for up to one month. Thaw in the fridge before serving.
  • Possible variations: Substitute chocolate wafer cookies for the Oreos. The bars will be a little less sweet. If you're not into Oreo cookies, substitute 2 cups mini chocolate chips for the crushed cookies. Stir one cup into the cookie dough and sprinkle one cup on top. Try double chocolate Oreo cookie bars. Add a half cup of cocoa powder to the cream cheese layer, reducing the powdered sugar by a half cup.
