Slutty Brownies

Slutty Brownies are an indulgent layered treat combining a cookie dough base, a middle layer of oreo cookies, and a rich chocolate brownie topping. The cookie dough includes brown and granulated sugars, eggs, oats, and chocolate chips, while the brownie layer adds cocoa powder and espresso powder for depth. The oreos form a textured barrier between the soft cookie and fudgy brownie layers. This dessert offers contrasting textures and chocolate flavors in a single bar.

Description

Slutty Brownies start with a homemade cookie dough layer made from butter, sugars, egg, vanilla, flour, baking powder, baking soda, salt, oats, and chocolate chips. Half of this dough is pressed into the pan as the base. The second layer consists of chocolate sandwich cookies (like Oreos) placed evenly atop the cookie dough, creating a crunchy middle contrast. On top is a cocoa-based brownie batter enriched with espresso powder to deepen the chocolate intensity.

The assembled pan is baked to meld the layers into a multi-textured bar: a chewy cookie bottom, a crunchy Oreo center, and a dense, fudgy chocolate brownie top. Allowing the brownies to cool before slicing helps maintain clean cuts and layered definition. Multiple chocolate types may be used in the dough and brownies to customize flavor.

These brownies are enjoyed as a decadent dessert or snack. Cut into smaller pieces for sharing or serving alongside coffee or milk. The recipe offers room to add caramel-filled chocolates or more broken Oreos to fill gaps among the cookies for more variety in texture.

Notes recommend letting the baked brownies cool completely before cutting to ease slicing and encourage experimenting with different chocolate blends in both cookie and brownie layers. The dessert resists crisp layering perfectly when eaten hot but benefits from resting.

Ingredients

Servings

Cookie Dough:

  • 1 cup butter softened, 226g, unsalted
  • ¾ cup brown sugar 150g
  • 1/2 cup granulated sugar 100g
  • 1 egg
  • 2 tsp. vanilla extract 10mL
  • 2 cups all-purpose flour 240g
  • 1 ¼ tsp. kosher salt
  • ½ tsp. baking powder
  • ¼ tsp. baking soda
  • 1 cup chocolate chips semi-sweet
  • ½ cup quick oats

Cookie Layer:

  • 18 chocolate sandwich cookies such as Oreos

Brownie Layer:

  • 3/4 cup butter melted, unsalted
  • ½ cup brown sugar 100g
  • ½ cup granulated sugar 100g
  • 2 tsp. vanilla extract 10mL
  • 2/3 cup cocoa powder 65g
  • ½ cup all-purpose flour 60g
  • 2 tsp. espresso powder
  • ½ tsp. kosher salt
  • ½ tsp. baking powder
  • 2 egg
  • ½ cup chocolate chips semi-sweet

Instructions

Make the Cookie Dough:

  1. Using a stand or hand mixer, beat butter and sugars in a bowl until creamy, about 2 minutes. Beat in egg and vanilla until combined.
  2. In a separate bowl, stir together flour, salt, baking powder, and baking soda. Gradually add flour mixture to butter mixture, beating on low speed until just combined.
  3. Fold in both chocolates and oats until just combined (do not overbeat).
  4. Divide dough in half; spread half of dough in an even layer in the bottom of a foil-lined, greased 9x9-inch baking pan. Set pan aside while making brownie layer.
  5. Refrigerate remaining dough for 15 minutes; reserve for additional cookies (see note below).

Make the Cookie Layer:

  1. Place the Oreos on top of the cookie dough layer; breaking cookies to fit, as needed.

Make the Brownie Layer:

  1. Preheat oven to 350°F. Mix the cocoa powder, flour, espresso powder, and baking powder in a bowl then set aside.
  2. In a medium bowl, beat together melted butter, sugars, eggs, and vanilla. Mix very well as this step gives you that nice brownie top.
  3. Sift the dry mixture into the butter mixture; stir until no streaks remain then fold in the chocolate chips.
  4. Pour brownie batter over Oreo layer; gently smooth top with an offset spatula.
  5. Bake at 350° until a wooden pick inserted comes out mostly clean, 35 to 40 minutes.
  6. For best slicing results, let cool completely, about 2 hours.
  7. Using foil as handles, lift brownies from pan. Discard foil; cut brownies into desired shapes.
  8. Store in an airtight container up to 3 days, or refrigerate up to 1 week, if you can resist them that long!

Notes

  • Allow brownies to cool thoroughly for a couple of hours before slicing to achieve clean cuts and maintain layers.
  • Feel free to customize by adding caramel-filled chocolates or additional broken Oreos among the cookie layer for texture variation.
  • Use any chocolate blend you prefer for the cookie dough and brownie layers, including dark or milk chocolate.
