Ingredients You’ll Need
These ingredients are straightforward but essential to crafting the perfect Oreo brownies. Each one plays a special role in creating that moist texture, deep chocolate flavor, and those tempting Oreo bits that make this dessert stand out.
- Unsalted butter (3/4 cup): Melted to add rich moisture and buttery flavor to the brownies.
- Vegetable oil (3 tablespoons): Keeps the brownies tender and helps with that perfectly fudgy texture.
- Granulated sugar (1 1/2 cups): Sweetens the batter while also contributing to a slight crisp on the edges.
- Large eggs (2) plus 1 egg yolk: Eggs provide structure and richness while ensuring a luscious chewiness.
- Vanilla extract (2 teaspoons): Enhances the chocolate flavor and adds a subtle warmth.
- All-purpose flour (3/4 cup): Keeps the brownies tender without making them cakey.
- Unsweetened cocoa powder (1/2 cup): Brings deep, intense chocolate notes that define a classic brownie.
- Salt (1/4 teaspoon): Balances sweetness and intensifies flavors.
- Chocolate chips (1 cup): Melts into pockets of gooey richness inside the browned batter.
- Oreo cookies (15, roughly chopped): The star ingredient that adds a delightful crunch and iconic flavor throughout.
How to Make Oreo Brownies Recipe
Step 1: Prepare Your Oven and Pan
Start by preheating your oven to 350°F (175°C). Line a 9×9-inch baking pan with parchment paper, leaving enough overhang on the sides so you can easily lift the brownies out after they bake. This step ensures clean edges and effortless removal, making the whole process smoother.
Step 2: Combine the Fats and Sugar
In a large mixing bowl, pour your melted unsalted butter. Add the vegetable oil and granulated sugar, stirring until the mix feels silky smooth. This combination builds the buttery foundation and sweetness, crucial for that melt-in-your-mouth brownie texture.
Step 3: Incorporate the Eggs and Flavor
Beat in the eggs and egg yolk one at a time, whisking thoroughly after each addition. This method ensures your batter is airy and smooth. Stir in the vanilla extract next—it brightens the chocolate flavor, giving these Oreo brownies their irresistible aroma.
Step 4: Add the Dry Ingredients
Sift together the all-purpose flour, unsweetened cocoa powder, and salt. Gently fold these dry ingredients into the wet batter using a spatula or wooden spoon. The key here is to mix just until combined; overmixing can lead to tough brownies, so keep it gentle to retain that tender crumb.
Step 5: Fold in Chocolate Chips and Oreos
Pour half of the chocolate chips and half of your roughly chopped Oreos into the batter. Fold them in evenly so every brownie bite has a perfect combo of chocolate and crunch, building layers of texture you’ll adore.
Step 6: Prepare for Baking
Transfer your luscious batter into the prepared baking pan, smoothing the top with a spatula. Sprinkle the remaining chocolate chips and Oreo pieces on top, pressing them gently into the batter so they stay visible and add to the visual and textural appeal.
Step 7: Bake to Perfection
Bake the brownies for 35 to 40 minutes. The edges should look firm and slightly pull away from the sides of the pan, while the center stays a bit soft and moist. A toothpick inserted in the middle should come out with a few moist crumbs but not wet batter. This baking time hits the perfect fudgy balance.
Step 8: Cool and Cut
Remove from the oven and allow the brownies to cool in the pan for at least 20 minutes. Using the parchment paper overhang, lift the entire brownie slab onto a cutting board. Slice into 12 squares and get ready to indulge in every gooey, crunchy bite!
How to Serve Oreo Brownies Recipe

Garnishes
To make these Oreo brownies look even more tempting, sprinkle a little powdered sugar or drizzle warm chocolate sauce over each piece. Adding a few crushed Oreos on top can amp up the visual and flavor impact, making them look like they came straight from an elegant bakery.
Side Dishes
These brownies pair wonderfully with a scoop of vanilla or cookies-and-cream ice cream for that extra creamy contrast. A glass of cold milk or a rich hot coffee complements the deep chocolate flavor perfectly and turns dessert time into a cozy moment.
Creative Ways to Present
Serve your Oreo brownies on a rustic wooden platter with a dusting of cocoa powder around the edges for a café-style touch. You can also create mini brownie bites by cutting them into tiny squares and skewering with decorative toothpicks—perfect for parties or sharing with friends.
Make Ahead and Storage
Storing Leftovers
Keep any leftover brownies fresh by placing them in an airtight container at room temperature. They’ll stay moist and fudgy for up to 3 days, perfect for snacking or surprising guests.
Freezing
If you want to make a batch ahead of time, wrap individual brownies tightly in plastic wrap and place them in a freezer-safe container or bag. Frozen brownies can last up to 3 months and thaw quickly at room temperature when you’re ready to enjoy.
Reheating
Warm your brownies gently in the microwave for 15 to 20 seconds or pop them in a low oven (300°F) for a few minutes to bring back that just-baked softness and melty chocolate chips. They taste like you just made them!
FAQs
Can I substitute the vegetable oil with another oil?
Yes, you can use light-flavored oils like canola or melted coconut oil for a slightly different taste and texture, but vegetable oil works best for that true fudgy brownie feel.
Do I have to chop the Oreos or can I use them whole?
Chopping the Oreos distributes their flavor and crunch evenly. Whole Oreos would not mix well and could make slicing difficult—plus, chopped pieces give you that delightful Oreo surprise in every bite.
Can I add nuts to this Oreo Brownies Recipe?
Absolutely! Chopped walnuts or pecans complement the chocolate and Oreo flavors beautifully, adding an extra layer of crunch and a nutty dimension.
What if I don’t have parchment paper for lining the pan?
You can grease the pan well with butter and flour, but parchment paper helps prevent sticking and makes it super easy to lift the brownies out without breaking them.
Are these brownies cakey or fudgy?
This Oreo Brownies Recipe yields brownies that are wonderfully fudgy with a bit of chew, thanks to the perfect balance of butter, oil, and eggs. If you prefer cakier brownies, you’d need a different ratio of ingredients.
Final Thoughts
I can’t recommend this Oreo Brownies Recipe enough — it’s a showstopper whether you’re baking for family, friends, or just treating yourself. The combination of rich chocolate and crunchy Oreos creates a magical dessert experience, and the recipe’s simplicity means you’ll want to make it again and again.
