Brookie Bars with Oreos at the Table

Oreo Brookie Bars are the standout dessert mash-up, combining rich brownie batter, chewy cookie dough, and crunchy Oreo cookies into one indulgent bite. Whether you’re making them for a party or just treating yourself, these bars are guaranteed to disappear fast.

What Are Brookie Bars?

Oreo brookie bars take the classic brookie to the next level by layering crushed Oreos into the mix. Traditional brookies blend brownie batter and chocolate chip cookie dough to create a dessert that’s part brownie, part cookie. But with Oreos added to the equation, you get even more chocolatey crunch and silky sweetness in every bite.

The beauty of these bars is their texture — fudgy, chewy, and just the right amount of crackly on top. They bake up with distinct layers but come together into an irresistible combination. Whether you love brownies, cookies, or Oreos, these bars bring them all together in one simple recipe.

Ingredients You Need

Brownie Mix – We love using a boxed brownie mix for convenience. It keeps this recipe speedy and simple while still delivering rich, chocolatey flavor.
Chocolate Chip Cookie Dough – Store-bought dough makes this recipe even simpler, but if you have time, from-scratch cookie dough adds a personal touch and extra chewiness.
Oreo Cookies – Crushed Oreos add crunch and extra layers of chocolate flavor. Use classic Oreos or switch it up with your go-to variety.

How to Make Oreo Brookie Bars

Prepare the brownie batter. Follow the instructions on the brownie mix box, stirring until smooth. Pour the batter into a parchment-lined baking pan.
Make the cookie dough. If using from-scratch dough, cream the butter and sugars together before mixing in the dry ingredients and chocolate chips. Otherwise, take your store-bought dough out of the fridge and let it soften slightly.
Layer the ingredients. Crumble the cookie dough over the brownie batter, making sure to leave some gaps so the brownie layer can peek through. Sprinkle crushed Oreos on top for extra crunch.
Bake until set. Keep an eye on the bars as they bake — once the top is golden and the brownie layer is firm, they’re ready to come out of the oven.
Cool and slice. Let the bars cool completely before cutting to ensure clean slices and the finest texture.

Variations

Cookies – Try using different flavors like peanut butter, birthday cake, or mint Oreos for a fun twist.
Cookie Dough – Swap the chocolate chip cookie dough for peanut butter, sugar cookie, or white chocolate macadamia nut dough.
Mix-Ins – Stir in chopped nuts, marshmallows, or extra chocolate chips for more texture and flavor.
Sauce – Drizzle caramel or hot fudge over the top before baking for a melty, indulgent touch.
Topping – Sprinkle crushed pretzels or toffee bits over the top for a salty-sweet combination.
Miniature – Bake the batter in a muffin tin for individual brookie bites reliable for snacking.

Can I Store Leftovers?

If left at room temperature, these bars stay soft and chewy for a couple of days, but the Oreos may lose their crunch over time.

For longer storage, keep them in an airtight container in the fridge for up to 1 week.

To freeze, wrap the individual bars in plastic wrap and store them in a freezer-safe bag for up to 3 months. Let them thaw at room temperature before serving.

Common Questions About Oreo Brookie Bars

What makes a brookie different from a regular brownie?

A brookie combines two types of dessert — brownies and cookies — so it has a fudgy brownie base with a chewy cookie layer on top. This version adds Oreos for extra crunch and chocolate flavor.

Can I use from-scratch brownie mix instead of boxed?

Absolutely! If you have a go-to brownie recipe, feel free to use it instead of a boxed mix. Just make sure the batter is thick enough to hold up against the cookie dough layer.

How do I know when brookie bars are done baking?

The edges should be firm and golden, and the center should no longer look wet. You can insert a toothpick into the brownie portion — if it comes out with just a few tender crumbs, they’re ready.

Can I make these bars ahead of time?

Yes! These bars actually taste even better the next day as the flavors meld together. Just store them in an airtight container at room temperature or in the fridge.

Notes

*We use Betty Crocker brownie mix, but any boxed variety that calls for a 13×9 baking dish wil work great. To freeze, transfer the bars to an airtight container or sealable bag. Store in the freezer for up to 2-3 months. Let them thaw in the fridge overnight and come to room temperature before serving.
