Oreo brookies take everything I love about classic brookies and push it one step further. Imagine fudgy brownie, soft cookie dough, and chunks of Oreo cookies all baked into one delicious bar.
I used my go-to chocolate chip cookie dough and layered it over rich brownie batter, then added Oreo cookies for extra crunch and flavor. It’s like a triple treat—cookie, brownie, and Oreo in every single bite.
If you’re into over-the-top chocolatey desserts like my Oreo cheesecake brownies bars or these Oreo brownie cookies, you’re going to love these. They’re easy to slice, perfect for parties, and always a hit with kids. Add a scoop of ice cream and you’re good to go!
Why you'll love this recipe
Ingredients You Need
Here’s everything you need to make these gooey Oreo brookie bars at home.
- All-purpose flour – gives structure to both the brownie and cookie layers. You can use cake flour for a slightly softer texture.
- Unsweetened cocoa powder – for that deep, rich chocolate flavor in the brownie base.
- Unsalted butter – melted for the brownie layer and softened for the cookie dough, it adds richness and moisture.
- Brown sugar & granulated sugar – the mix adds sweetness and depth. Brown sugar brings a hint of caramel/molasses flavor.
- Large eggs – at room temperature, they help bind the ingredients and give structure.
- Baking powder – helps the cookie layer rise slightly and stay soft. You can swap it with baking soda if needed.
- Vanilla extract & salt – vanilla adds flavor, and a pinch of salt enhances the overall taste.
- Chocolate chips – use semi-sweet or milk chocolate chips for melty pockets in every bite.
- Oreo cookies – crushed or whole, regular or double-stuffed, they add crunch and Oreo flavor to both layers.

Step 1: In a large mixing bowl, whisk together the melted butter, white sugar, brown sugar, and unsweetened cocoa powder until smooth.

Step 3: Stir in the flour, salt, and chocolate chips until you get a thick, fudgy batter.

Step 5: In a separate bowl, beat the softened butter with white sugar and brown sugar until light and creamy.
Step 6: Add the egg and vanilla extract, and mix until smooth and stir in the flour, salt, baking powder, and chocolate chips with a spatula until fully combined.
Step 7: Spread the chocolate chip cookie dough over the Oreo layer, covering all the cookies. Add extra chocolate chips and crushed Oreos on top if you like.
Step 8: Bake in a preheated oven at 350°F (180°C) for about 30–35 minutes, or until the top is golden brown and the center is just set.

Tips for this recipe
How to Store and Freeze
To serve again: Let them thaw at room temperature, or use the microwave’s defrost function if you're in a hurry. You can even warm them up slightly for that gooey, just-baked texture.
Room temperature: Keep your Oreo brookies fresh by storing them in an airtight container at room temp. They stay soft and chewy for up to 5 days—perfect for snacking all week!
Freezing instructions: Got leftovers? These bars freeze really well. Place them in a freezer-safe container or wrap them individually in plastic wrap and foil. Freeze for up to 3 months.

Recipe Questions
Can I use a boxed brownie mix instead of homemade batter?
Yes! A brownie mix works great if you're short on time. Just follow the package instructions, then layer with Oreos and cookie dough as described in the recipe.
How do I know when the brookies are done baking?
They’re ready when the top is golden and a toothpick inserted comes out with moist crumbs. Avoid overbaking—brookies continue to set as they cool.
What can I use instead of Oreos?
Try swapping Oreos with other sandwich cookies, peanut butter cookies, or even flavored Oreos like mint or birthday cake.
Why is my cookie dough too sticky to spread?
Chill the dough for 10–15 minutes, or grease your spatula (or hands) lightly with oil or butter to make spreading easier.

Instructions
Brownie Batter
-
In a bowl, combine the melted butter, eggs, granulated sugar, brown sugar, vanilla extract, and cocoa powder. Mix with an electric mixer until smooth and well combined.
-
Add the dry ingredients—flour, baking powder, salt, and chocolate chips—and mix with a spatula until fully incorporated and smooth.
-
Pour the brownie batter into a square baking pan lined with parchment paper, and smooth it out evenly with an offset spatula.
-
Place the Oreo cookies on top of the brownie layer, gently pressing them into the batter.
Cookie Dough
-
In a separate bowl, mix the melted butter with the granulated sugar and brown sugar using an electric mixer for about 1 minute.
-
Add the egg and vanilla extract, and beat again until well incorporated.
-
Add the dry ingredients—flour, baking powder, salt, and chocolate chips—and fold them in with a spatula until the dough is smooth and evenly mixed.
-
Spread the cookie dough evenly over the Oreo layer, making sure all the cookies are fully covered.
-
Top with extra Oreo pieces and bake in a preheated oven at 350°F (180°C) for about 30 minutes, until golden on top but still slightly soft in the center. (Check doneness by inserting a toothpick in the middle—it should come out with moist brownie crumbs, not wet batter.)
