Step‑by‑Step Instructions for Oreo Brookies
Step 1: Preheat the Oven
Begin by preheating your oven to 350℉ (175℃). While the oven heats up, prepare a 9×13-inch baking dish by buttering it generously or lining it with parchment paper for easy removal. This step is crucial for achieving that perfect chewy texture in your Oreo Brookies.
Step 2: Prepare the Brownie Layer
In a microwave-safe bowl, melt the milk chocolate chips and butter together in 30-second intervals, stirring after each until smooth. Allow the mixture to cool slightly before mixing in granulated sugar, eggs, cocoa powder, all-purpose flour, vanilla extract, and salt. Finally, fold in broken Oreo pieces for that delightful crunch, ensuring they’re evenly distributed throughout the batter.
Step 3: Make the Cookie Dough Layer
In a separate mixing bowl, cream together softened butter, brown sugar, granulated sugar, egg, and vanilla extract until light and fluffy. Gradually mix in the baking soda, salt, all-purpose flour, and chocolate chips until just combined. This cookie dough layer, when layered with the brownie mix, will create the ultimate Oreo Brookies sensation.
Step 4: Assemble the Brookies
Using a spoon, drop alternating dollops of the brownie batter and cookie dough into the prepared baking dish. Fill gaps as necessary, but ensure there’s room for the dough to spread during baking. The marbled layers will create a beautiful, swirled design in your Oreo Brookies as they bake.
Step 5: Add Extra Oreos
For an extra punch of flavor and texture, top the assembled Brookies with additional Oreo cookie halves, gently pressing them into the batter. This not only enhances the flavor but also provides an attractive finish to your completed dessert, inviting everyone to indulge.
Step 6: Bake to Perfection
Place the baking dish in the preheated oven and bake for 30-35 minutes. Start checking for doneness at the 25-minute mark; the cookie layer should be golden but not too dark. If necessary, cover the dish with foil to prevent over-browning. Once done, let the brownies cool in the pan to set before cutting into bars.
Step 7: Serve with Love
Once the Oreo Brookies have cooled for at least 15 minutes, slice them into generous squares. Serve them warm, perhaps with a scoop of vanilla ice cream on top, to fully enjoy the delightful combination of flavors and textures. Your family and friends will be delighted with this heavenly treat!

Oreo Brookies Recipe FAQs
What type of Oreos should I use for the best flavor?
Absolutely! Original Oreos are perfect, but feel free to get creative! You can use flavored variants like Halloween or Mint Oreos for a fun twist. Just keep in mind, using different flavors will slightly alter the overall taste of your Oreo Brookies.
How should I store my Oreo Brookies to keep them fresh?
I recommend storing your Oreo Brookies in an airtight container at room temperature for up to 3 days. If you want them to last longer, place them in the refrigerator where they can stay fresh for up to a week. Just be sure to let them come to room temperature before serving, as the flavor truly shines when they’re slightly warm.
Can I freeze Oreo Brookies for later enjoyment?
Yes, absolutely! To freeze, first, wrap individual bars tightly in plastic wrap, then place the wrapped bars into a freezer-safe bag. They will stay fresh for up to 3 months. When you’re ready to indulge, simply thaw them at room temperature for a few hours or pop them in the microwave for a few seconds to bring back that delicious gooeyness.
What should I do if my brownie layer is too thin or burns on top?
Very! To avoid a burnt top, keep an eye on your Brookies after about 25 minutes of baking; cover them with aluminum foil if they seem to be darkening. If your brownie layer ends up too thin, double-check the measurements next time. Using quality ingredients, such as fresh eggs and proper cocoa powder, can make a big difference in texture.
Can I make Oreo Brookies gluten-free?
You sure can! To make a gluten-free version, simply substitute the all-purpose flour with a gluten-free flour blend. Just be sure to adjust the baking time as needed. For optimal results, look for a blend that includes a bit of xanthan gum to help with the texture.
Are Oreo Brookies suitable for pets or anyone with allergies?
No, it’s best to keep these delicious treats away from pets, especially chocolatey treats like these! Additionally, if you have guests with allergies to eggs or gluten, it’s great to make alternative recipes specifically tailored to their dietary needs or inquire with them before serving these decadent bars.
