These Cookie Dough Oreo Brownies are three desserts in one pan: a layer of chocolate chip cookie dough on the bottom, a row of Oreo cookies in the middle, and rich, fudgy brownie batter poured over the top. Baked together, the cookie layer turns soft and buttery, the Oreos go tender and cakey, and the brownie top gets that shiny, crackly crust everyone fights over.
You may have seen them online under their cheeky nickname, “slutty brownies.” Whatever you call them, they are wildly indulgent and surprisingly easy. Below you will find a from-scratch version of each layer (with shortcuts if you want to use store-bought dough and mix), how to tell when they are done, and how to get clean squares.

What makes these cookie dough Oreo brownies so good?
It is all about contrast. The cookie dough base is buttery with pockets of melted chocolate chips; the Oreos add a creamy, cookies-and-cream layer; and the brownie on top is dense and fudgy. Because the cookie dough and brownie bake at the same temperature, everything finishes at the same time in one pan.
In the viral video the layers are built straight from store-bought refrigerated cookie dough and a box of brownie mix, which is a perfectly good shortcut. The homemade version below tastes richer and lets you control the sweetness, and it only takes a couple of extra bowls.
The most common mistake? Cutting them while they are warm. Fresh from the oven the center is molten and the layers slide apart. Let the pan cool completely, at least 2 hours (or chill for 30 minutes), before slicing for neat squares. Scooping warm with a spoon, as in the video, is delicious but messy.
Key ingredients and why they matter
| Key Ingredient | What To Use | Why It Matters |
|---|---|---|
| Butter | Unsalted butter, softened for cookie dough, melted for brownies | Flavor and the chewy-fudgy texture in both layers. |
| Brown sugar | Light or dark brown sugar | Keeps the cookie layer soft and caramel-like. |
| Cocoa powder | Unsweetened natural or Dutch-process cocoa | Deep chocolate flavor in the brownie top. |
| Oreo cookies | Original Oreos (about 24) | The creamy middle layer that gives the bars their look. |
| Chocolate chips | Semi-sweet chips | Melty pockets in the cookie base. |
| Eggs | Large eggs, room temperature | Structure, and the shiny crackly brownie crust. |
Cookie Dough Oreo Brownies
A chocolate chip cookie dough base, a layer of Oreos and fudgy brownie batter baked together in one pan.
Ingredients
- Cookie layer: 1/2 cup (113 g) unsalted butter, softened
- Cookie layer: 1/2 cup packed brown sugar and 1/4 cup granulated sugar
- Cookie layer: 1 large egg and 1 teaspoon vanilla extract
- Cookie layer: 1 1/4 cups all-purpose flour, 1/2 teaspoon baking soda, 1/4 teaspoon salt
- Cookie layer: 1 cup semi-sweet chocolate chips
- Middle: about 24 Oreo cookies
- Brownie layer: 3/4 cup (170 g) unsalted butter, melted
- Brownie layer: 1 1/2 cups granulated sugar
- Brownie layer: 3 large eggs and 2 teaspoons vanilla extract
- Brownie layer: 3/4 cup unsweetened cocoa powder
- Brownie layer: 3/4 cup all-purpose flour and 1/2 teaspoon salt
Instructions
- Heat the oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving an overhang on two sides, and grease it lightly.
- Make the cookie layer: beat the softened butter with the brown and granulated sugar until creamy, then beat in the egg and vanilla. Mix in the flour, baking soda and salt until just combined, then fold in the chocolate chips.
- Press the cookie dough evenly into the bottom of the pan with a spatula or lightly floured fingers.
- Arrange the Oreos in a single layer on top of the cookie dough, about 4 across and 6 down.
- Make the brownie layer: whisk the melted butter and sugar together, then whisk in the eggs one at a time and the vanilla until glossy. Sift in the cocoa, flour and salt and fold until no dry streaks remain.
- Pour the brownie batter over the Oreos and spread it gently to the edges so the cookies are covered.
- Bake for 35–40 minutes, until the top is set and crackly and a toothpick inserted 2 inches from the edge comes out with moist crumbs. Cool completely in the pan, then lift out with the parchment and cut into 24 squares.
Shortcut vs. from scratch
| Layer | Shortcut | From Scratch | Tip |
|---|---|---|---|
| Cookie dough | 16 oz tub or tube refrigerated dough | Recipe above | Let store-bought dough soften 10 minutes so it spreads. |
| Oreos | Original Oreos | Any sandwich cookie | Double Stuf makes a gooier middle. |
| Brownie | Family-size brownie mix (about 18 oz) | Recipe above | Prepare the mix as directed on the box. |
| Bake time | 40–45 minutes | 35–40 minutes | Check early; ovens vary. |
Common problems and how to fix them
| Problem | Likely Cause | Easy Fix |
|---|---|---|
| Raw, gooey center | Underbaked or a glass pan | Bake 5–10 minutes longer; glass pans heat slower than metal. |
| Dry, crumbly edges | Overbaked | Pull them when the center still has moist crumbs; they firm as they cool. |
| Layers sliding apart | Cut while warm | Cool completely or chill 30 minutes before slicing. |
| Oreos floating up | Batter too thin over the cookies | Spoon batter between the cookies first, then over the top. |
| Messy squares | Dull or dry knife | Use a large sharp knife, wiped clean and warmed under hot water between cuts. |
Tips and variations
- Use a metal pan: Metal bakes more evenly than glass; if you use glass like the video, add a few minutes and check often.
- Swap the middle: Try peanut butter cups, Biscoff cookies or mint Oreos instead of the originals.
- Salted finish: Sprinkle flaky sea salt over the brownie batter before baking.
- Serve warm: For a dessert-for-a-crowd moment, scoop it warm into bowls with vanilla ice cream.
- Storage: Keep covered at room temperature for up to 3 days, or freeze individual squares for up to 3 months.
How to get the perfect crackly brownie top
That thin, shiny, paper-like crust on top of a great brownie comes from sugar that has partly dissolved in the eggs and melted butter. When the batter bakes, that sugary layer rises to the surface and dries into a glossy meringue-like skin. To get it every time, whisk the warm melted butter and sugar together first, then whisk each egg in vigorously for 20–30 seconds until the batter looks thick, pale and glossy before adding the dry ingredients.
Once the cocoa and flour go in, switch to a spatula and fold only until no dry streaks remain. Overmixing at this stage develops gluten and gives you a cakey brownie instead of a fudgy one. Spread the batter gently over the Oreos rather than pressing it, so the cookie layer underneath stays intact.
Pan size matters too. A 9×13-inch pan gives you three distinct layers about 1 1/2 inches tall. A smaller pan makes thicker bars that need a longer bake and lower oven temperature (325°F) so the edges do not overcook before the cookie dough in the center sets. If you are baking for a party, cut the cooled slab into 24 squares, or 48 small bites, since these are very rich.

Frequently Asked Questions
Why are they called slutty brownies?
It is a playful internet nickname for these over-the-top layered bars that combine cookie dough, Oreos and brownie in one pan. Many bakers call them cookie dough Oreo brownies or triple-layer brownies instead.
Can I use store-bought cookie dough and brownie mix?
Yes. Use a 16 oz package of refrigerated chocolate chip cookie dough and a family-size box of brownie mix prepared as directed, then bake for 40–45 minutes.
How do I know when the brownies are done?
The top should look set and crackly and a toothpick inserted about 2 inches from the edge should come out with moist crumbs, not wet batter. The center will firm up as it cools.
Can I make these in an 8×8 pan?
Halve every ingredient and use an 8×8-inch pan with 9 Oreos. Start checking at about 30 minutes.
Is the cookie dough layer safe to eat?
Yes, once baked. The cookie dough layer contains raw egg and flour, so it must be fully baked with the brownies and should not be eaten raw.
