Craving the ultimate dessert indulgence? Slutty Brownies are your answer.

These triple-layered treats combine soft chocolate chip cookie dough, crunchy Oreo cookies, and gooey, fudgy brownie batter in one pan.

They’re more than just a dessert—they’re a viral sensation loved by chocolate fans everywhere.

Each bite delivers a perfect harmony of textures and flavors that’s impossible to resist.

Here’s how to easily make these iconic brownies at home!

What Are Slutty Brownies?

Slutty Brownies are a decadent dessert made up of three indulgent layers: a base of chewy chocolate chip cookie dough, a middle layer of crunchy Oreo cookies, and a rich, fudgy brownie layer on top.

Their name, while playful, reflects the over-the-top nature of combining three already delicious desserts into one irresistible treat.

Each layer brings a unique texture and flavor—soft and buttery cookie dough on the bottom, the crisp and creamy Oreo center, and a dense, chocolate-loaded brownie topping.

Together, these layers create a dessert that is unapologetically indulgent and perfect for satisfying even the most intense chocolate cravings.

Ingredients Needed

To make Slutty Brownies, you’ll need a handful of simple ingredients for each layer.

Here’s what you’ll need to create these indulgent treats:

For the Cookie Dough Layer

• 1 cup unsalted butter (softened, 226g)
• ¾ cup brown sugar (150g)
• ½ cup granulated sugar (100g)
• 1 large egg
• 2 teaspoons vanilla extract (10mL)
• 2 cups all-purpose flour (240g)
• ½ teaspoon baking soda
• 1 ¼ teaspoons kosher salt
• 1 cup semi-sweet chocolate chips (170g)

For the Oreo Layer

• 18 Oreo cookies (regular or double-stuffed)

For the Brownie Layer

• ¾ cup unsalted butter (melted, 170g)
• ½ cup brown sugar (100g)
• ½ cup granulated sugar (100g)
• ⅔ cup cocoa powder (65g)
• ½ teaspoon kosher salt
• 2 teaspoons vanilla extract (10mL)
• 2 large eggs
• ½ cup all-purpose flour (60g)

Step-by-Step Instructions

Step 1: Preparing the Cookie Dough Layer

Start by creaming together 1 cup of softened unsalted butter, ¾ cup of brown sugar, and ½ cup of granulated sugar in a large mixing bowl.

Use a hand or stand mixer and beat the mixture until it’s light and fluffy, about 2 minutes.

Next, add 1 large egg and 2 teaspoons of vanilla extract, mixing until fully incorporated.

In a separate bowl, whisk together 2 cups of all-purpose flour, ½ teaspoon of baking soda, and 1 ¼ teaspoons of kosher salt.

Gradually add this dry mixture to the wet ingredients, mixing just until combined.

Finally, fold in 1 cup of semi-sweet chocolate chips using a spatula.

Press the prepared dough evenly into the bottom of a 9×9-inch baking pan lined with parchment paper.

Make sure to spread it into an even layer to serve as the base.

Step 2: Adding the Oreo Layer

Once the cookie dough is in place, arrange 18 Oreo cookies (regular or double-stuffed) in a single layer over the dough.

Press them gently into the surface to ensure they stay in place.

Make sure the entire cookie dough layer is covered, breaking Oreos in half if needed to fill any gaps.

Step 3: Preparing the Brownie Layer

In a medium-sized saucepan, melt ¾ cup of unsalted butter over low heat.

Remove the pan from the heat and whisk in ½ cup of brown sugar, ½ cup of granulated sugar, and ⅔ cup of cocoa powder until the mixture is smooth.

Let it cool slightly before adding 2 large eggs and 2 teaspoons of vanilla extract.

Whisk the mixture until it becomes glossy and thick.

Gently stir in ½ cup of all-purpose flour and ½ teaspoon of kosher salt, mixing just until the flour disappears. Be careful not to overmix.

Pour the brownie batter evenly over the Oreo layer, spreading it to cover the cookies completely.

Step 4: Baking

Preheat your oven to 350°F (175°C).

Place the assembled pan in the oven and bake for 35-40 minutes.

To check for doneness, insert a toothpick into the center.

It should come out with a few moist crumbs but not raw batter.

Once baked, allow the brownies to cool completely in the pan.

This step is crucial for clean slicing.

Cooling for at least 1-2 hours will give the layers time to set properly.

Once cooled, lift the brownies out of the pan using the parchment paper and slice them into squares.

Enjoy your perfectly layered Slutty Brownies!

Tips and Variations

Achieving the Perfect Texture

To ensure your Slutty Brownies turn out perfectly, start with room temperature ingredients.

This simple step helps the butter and sugars cream together smoothly and allows the other ingredients to incorporate evenly.

When mixing the cookie dough and brownie batter, avoid over-mixing, especially after adding the flour.

Over-mixing can lead to a dense or tough texture, which takes away from the soft and gooey layers that make these brownies irresistible.

A light hand during mixing will give you the tender, melt-in-your-mouth texture you’re looking for.

Flavor Variations

Slutty Brownies are incredibly versatile, and you can customize them to suit your preferences.

For a nutty twist, swap the Oreo layer with peanut butter cookies.

You can also experiment with other cookie flavors, like chocolate mint or cinnamon sugar, to create a unique version of this classic dessert.

Adding mix-ins to the brownie batter is another easy way to enhance the flavors.

Stir in chopped nuts, caramel bits, or even white chocolate chips for added texture and bursts of sweetness.

If you’re feeling festive, use seasonal Oreos or sprinkles to match a holiday theme.

Serving Suggestions

Slutty Brownies are delicious on their own, but serving them warm takes the experience to the next level.

For an indulgent treat, pair them with a scoop of vanilla ice cream.

The cold, creamy ice cream perfectly balances the warm, gooey brownies.

You can also drizzle them with caramel or chocolate sauce for an extra layer of decadence.

Storage and Shelf Life

To keep your Slutty Brownies fresh and delicious, store any leftovers in an airtight container.

At room temperature, they will stay fresh for up to 3 days.

If you want to extend their shelf life, refrigerate them in the same container for up to a week.

For even longer storage, you can freeze the brownies for up to 3 months.

To freeze, wrap each brownie individually in plastic wrap, then place them in a freezer-safe bag or container to prevent freezer burn.

When you’re ready to enjoy them, thaw the brownies at room temperature for a few hours, or warm them in the microwave for a gooey texture.
