These Layered Oreo Brookies are the ultimate dessert mashup with rich, fudgy brownies, a center layer of Oreos, and a chewy chocolate chip cookie top.
This triple-decker treat is basically three desserts in one – brownie, Oreo cookie, and chocolate chip cookie, all packed into a single 13×9 pan. The result is a big batch of rich, indulgent bars with plenty to share.
I’ve seen versions of this recipe floating around the internet since 2011, most made with store-bought ingredients, like boxed brownie mix and refrigerated cookie dough. I always wanted to try them but never got around to it, until now. My scratch-made version shakes things up a bit. Most recipes start with a cookie dough base, but I flipped the layers. By putting the brownie layer on the bottom, it bakes up extra fudgy, while the soften into a cake-like consistency. The cookie layer on top bakes to a crispy golden crust with a soft, chewy center – just how I like my cookies. In fact, these taste a lot like my favorite , except with a surprise Oreo cookie center.
The Brownie Layer
These Layered Oreo Brookies begin with brownies. Melt butter and semisweet chocolate together. I do this in the microwave in a big heat-proof mixing bowl, but you can do it in a saucepan on the stovetop, too. Let the mixture cool slightly, about 5 minutes.
Mix in the sugar, followed by the eggs, beating them in one at a time. Add the flour, cocoa powder, and salt. Mix until smooth and spread evenly in the pan, forming a dense foundation for all the layers above.
The Chocolate Chip Cookie Layer
With an electric mixer, beat together melted butter and packed brown sugar until smooth. Beat in eggs one at a time, followed by vanilla extract. Stir in flour, baking soda, and salt until a thick batter forms.
Mix in mini semisweet chocolate chips until they are dispersed throughout the thick batter. You could also use regular sized chocolate chips in equal amounts. This batter whipped up so beautifully – I was tempted to eat a big spoonful of the raw dough! But I didn’t. Because there’s a better (safer) recipe for that .
Assemble the Layers
Grease a 13×9 inch baking pan and line it with parchment paper that overhangs the edges. This creates a sling so you can lift the brookie sheet out of the pan easily.
Spoon or scoop the brownie batter into the greased and parchment-lined 13×9 inch pan. A trigger ice cream scoop works well – if you have one, use it! Spread it evenly to create a smooth base for the Oreo layer.
Add the Oreos
Arrange 24 Oreo cookies in a single layer on top of the brownie batter, spacing them evenly. Lightly press them in so they stay in place while baking.
Top with Chocolate Chip Cookie Dough
Again, spoon or scoop the chocolate chip cookie batter over the Oreos. Spread evenly with an offset spatula. Spread it into the corners for full coverage so the cookie layer bakes evenly over the brownies and Oreos.
Sprinkle with More Semisweet Chips
Once out of the oven, while still warm, sprinkle additional mini semisweet chocolate chips on top. The residual heat will slightly melt them, and when completely cool, they’ll stick to the top. I think this makes them look extra yummy.
Cool and Slice
Let the bars cool in the pan for 15-20 minutes before using the parchment overhang to lift them out. Allow them to cool completely before slicing into 24 bars with a sharp chef’s knife.
Because these bars have to bake for a long time, the edges will be crusty. You can trim those away and save them for ice cream toppings. But if you love a crusty edge, then just slice and serve. I recommend these with a tall glass of ice cold milk.
The combo of brownies, Oreos, and chocolate chip cookies make these Layered Oreo Brookies the ultimate dessert triple threat. Make a batch and share them with friends, bring them to a party, or stash a few away in the freezer for later (see recipe notes). If you make them, let me know how they turn out in the comments!
