What Are Slutty Brownies?

The Origin Story

The playfully named “Slutty Brownies” burst onto the baking scene in 2011, coined by the popular UK food blogger, The Londoner (Rosie). Her original creation, then known as “Ultimate Chocolate Chip Cookie n’ Oreo Fudge Brownie Bars,” quickly went viral, captivating home bakers worldwide with its sheer audacity and irresistible charm. The name, Rosie explained, came from how “oh so easy” and “filthy” (meaning outrageously indulgent and delicious) they were. It’s a cheeky, affectionate nod to their irresistible, layered nature that makes them so hard to resist. This dessert has also evolved into popular monikers such as Cookie Dough Oreo Brownies, Triple Layer Brownies, and Brookies with Oreos.

The Three Essential Layers

At the heart of every perfect Slutty Brownie is its iconic three-layer structure, each contributing to an unforgettable eating experience:

Bottom Layer: A robust, chewy foundation of chocolate chip cookie dough sets the stage. This layer bakes up into a soft, comforting base that perfectly complements the layers above.
Middle Layer: The delightful crunch and creamy filling of classic Oreo cookies. These aren’t just placed; they’re nestled in, adding a distinct textural contrast and that beloved chocolatey, creamy flavor. This is what transforms them into true Oreo Stuffed Brownies.
Top Layer: A generous, thick blanket of fudgy, rich brownie batter. When baked, this top layer creates a moist, gooey finish that ties all the components together in a harmonious blend of chocolatey goodness.

Ingredients & Equipment

The “Easy” Shortcut Version

The beauty of this Easy Slutty Brownies Recipe lies in its smart use of convenient ingredients that deliver big on flavor and texture.

Refrigerated Cookie Dough: A 16oz tube of chocolate chip cookie dough is your secret weapon. Brands like Pillsbury or Toll House work wonderfully, providing the perfect chewy base.
Oreo Cookies: One standard package (about 36 cookies) will do the trick. Regular Oreos offer classic crunch; Double Stuf can make the middle layer even creamier, but be aware they might make cutting slightly trickier due to their thickness.
Boxed Brownie Mix: Opt for a “fudge” variety over a “cakey” style mix for that ultimate gooey texture. Betty Crocker, Ghirardelli, or Duncan Hines fudgy brownie mixes are excellent choices.
Pantry Staples: You’ll need eggs, oil, and water – whatever your chosen brownie mix requires to prepare the batter.

Essential Tools

Baking Pan: An 8×8-inch pan will yield thicker, more substantial bars, while a 9×9-inch pan results in slightly thinner, quicker-baking treats. Choose based on your preference and adjust bake time accordingly.
Parchment Paper: Absolutely crucial! This creates a “sling” that allows you to easily lift the entire slab of brownies out of the pan for clean, effortless slicing.

Step-by-Step Instructions

Prepare Your Oven and Pan: Preheat your oven to 350°F (175°C). Line your chosen 8×8 or 9×9-inch baking pan with parchment paper, ensuring there’s an overhang on two sides. This overhang will act as your “sling.” Lightly grease the parchment paper to prevent sticking.
Lay the Cookie Dough Foundation: Unroll the entire tube of refrigerated chocolate chip cookie dough. Press it evenly and firmly into the bottom of the prepared pan, creating a solid, uniform foundation. Lightly floured hands or a piece of plastic wrap can help prevent sticking.
Nestle the Oreos: Carefully arrange the Oreo cookies in a single layer over the cookie dough. Try to tessellate them – fit them together like a puzzle – to cover as much of the surface as possible. Don’t worry if there are tiny gaps; the brownie batter will fill them.
Pour the Brownie Batter: Prepare your boxed brownie mix according to the package directions. Gently pour the brownie batter over the Oreo layer, spreading it carefully and evenly with a spatula. Take care to ensure it covers all the cookies without disturbing the layers below.
Bake to Perfection: Place the pan in the preheated oven. Bake for 30-40 minutes for an 8×8-inch pan, or 25-35 minutes for a 9×9-inch pan. Look for visual cues: the edges should be set, and a toothpick inserted into the brownie layer (avoiding the cookie dough) should come out with moist crumbs, not wet batter. Remember, a slightly gooey center is the goal for these perfect Fudgy Cookie Brownie Bars.

Expert Tips for the Best Results

Achieving Slutty Brownie perfection requires a few insider tricks:

The secret to truly decadent Slutty Brownies lies in patience and precise baking. Resist the urge to cut too soon!

Avoid Overbaking: The key to gloriously fudgy Loaded Brownie Recipe bars is to pull them from the oven when they’re just set. A slightly underbaked center is far better than dry, crumbly edges.
Cooling is Crucial: This is arguably the most important step! Resist the urge to cut into them hot. The layers need ample time to cool completely and set, allowing the chocolate, cookie, and brownie to solidify. Allow them to cool at room temperature for at least 2-3 hours, or even longer, before attempting to slice. This scientific necessity ensures clean cuts and perfect textural integrity.
Clean Cuts: For picture-perfect slices, use a sharp, hot knife. Dip your knife in hot water and wipe it clean between each cut. This technique works wonders for these Triple Layer Brownies, creating neat, impressive squares.
Tent with Foil: If you notice the top of your brownies browning too quickly during baking, loosely tent the pan with aluminum foil for the remaining baking time. This prevents over-browning while allowing the inside to finish cooking.

Variations and Customizations

These Brookies with Oreos are incredibly versatile, allowing for endless delicious customizations:

Peanut Butter Lover’s Dream: Swap out the regular chocolate chip cookie dough for a peanut butter cookie dough. For an extra kick, dot the brownie batter with mini peanut butter cups before baking.
The “Golden” Slutty Brownie: Embrace the lighter side! Use golden Oreos, swap the chocolate chip cookie dough for sugar cookie dough, and choose a blondie mix instead of brownie for a delightful vanilla-forward treat.
Elevated Toppings: Elevate your Decadent Dessert Bars even further! A sprinkle of flaky sea salt after baking enhances the chocolate notes beautifully. A warm caramel drizzle adds gooey sweetness, or serve them warm with a scoop of vanilla ice cream for the ultimate indulgence.
Mint Edition: Perfect for the holidays or a refreshing twist, simply use Mint Oreos in the middle layer. The cool mint flavor pairs wonderfully with the chocolate.

Storage and Reheating

Room Temperature: Store your Easy Slutty Brownies Recipe bars in an airtight container at room temperature for up to 3-4 days.
Refrigerating: Chilling them makes them even chewier and can extend their freshness for up to a week. Just be sure to bring them back to room temperature or warm them slightly before serving for optimal texture.
Freezing: For long-term storage, wrap individual brownies tightly in plastic wrap, then place them in a freezer-safe bag or container. They can be frozen for up to 2-3 months. Thaw at room temperature for the best results.
Reheating: A quick 10-15 second zap in the microwave will bring back that “fresh-baked” gooeyness, especially delightful when serving with a scoop of ice cream.

Frequently Asked Questions (FAQs)

Can I make these from scratch?

Absolutely! While this recipe emphasizes convenience, you can certainly make homemade chocolate chip cookie dough and brownie batter. Just ensure your scratch brownie recipe is fudgy, not cakey, to maintain the desired texture for these Ultimate Chocolate Chip Cookie Oreo Brownie Bars. You’ll simply follow the layering instructions as written.

Why is the middle of my brownie taking so long to cook?

The dense layers, especially the cookie dough base and the Oreos, can sometimes insulate the center of the brownie, causing it to cook slower than the edges. Ensure your oven temperature is accurate (an oven thermometer can help!). If the edges are setting too fast, loosely tent with aluminum foil for the remaining bake time. Remember, a slightly underbaked, gooey center is the ideal for a fudgy result, so don’t overdo it waiting for a completely clean toothpick.

Can I double the recipe for a 9×13 pan?

Yes, you can! A 9×13-inch pan is perfect for doubling the recipe. You’ll need two tubes of cookie dough, two packages of Oreos (or enough to cover the larger surface), and two boxes of brownie mix (or a large family-size mix). The baking time will likely increase to 45-60 minutes, so keep a close eye on it and check for doneness with a toothpick in the center.

Conclusion

There you have it – the definitive guide to mastering the Easy Slutty Brownies Recipe. This decadent, triple-layered treat is more than just a dessert; it’s a celebration of indulgence, convenience, and pure deliciousness. Whether you’re a seasoned baker or just starting out, these brownies are surprisingly simple to create and guaranteed to be a showstopper.

Prep Time 10

Cook Time 40

Total Time 50

Servings 16

Ingredients

16 oz Refrigerated Chocolate Chip Cookie Dough 1 standard tube
24 count Oreo Cookies Regular or Double Stuf (approx. 1 package)
18.3 oz Fudge Brownie Mix 1 standard family-size box
2 count Large Eggs Or quantity stated on brownie mix box
1/2 cup Vegetable Oil Or quantity stated on brownie mix box
1/4 cup Water Or quantity stated on brownie mix box

Instructions

Preheat your oven to 350°F (175°C). Line a 9x9-inch baking pan with parchment paper, leaving enough overhang on all sides to act as handles for lifting the brownies out later. Lightly grease the parchment.
Remove the cookie dough from the wrapper and press it firmly and evenly into the bottom of the prepared pan to form a solid base layer.
Arrange the Oreo cookies in a single flat layer directly on top of the cookie dough. Break a few cookies if necessary to fill any large gaps so every bite has a crunch.
In a medium bowl, prepare the brownie batter by combining the mix, eggs, oil, and water according to the package instructions. Stir until smooth.
Pour the brownie batter over the Oreo layer. Use a spatula to gently spread it to the corners, ensuring the cookies are completely covered.
Bake for 35 to 45 minutes. The brownies are done when the edges are set and a toothpick inserted into the center comes out with moist crumbs (avoid hitting an Oreo when testing). Do not overbake.
Remove from the oven and place the pan on a wire rack. Let the brownies cool completely in the pan for at least 2 to 3 hours to allow the layers to set properly.
Once cooled, use the parchment paper handles to lift the brownie slab out of the pan. Place on a cutting board and slice into 16 squares using a sharp knife.
