Step‑by‑Step Instructions for Oreo Brookies
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While the oven heats up, grab a 9×13 inch baking dish and either butter and flour it generously or line it with parchment paper for easy removal later. This preparation ensures that your Oreo Brookies will have a perfect, beautifully baked edge.
Step 2: Make the Oreo Brownie Batter
In a microwave-safe bowl, combine the milk chocolate chips and butter. Melt them in 30-second intervals, stirring until smooth. Once melted, mix in the granulated sugar until well combined, then add in the eggs and egg yolk. Gradually stir in the cocoa powder, flour, vanilla extract, and salt, and finally, fold in the broken Oreo pieces, creating a rich and fudgy brownie batter.
Step 3: Prepare the Chocolate Chip Cookie Dough
In a separate large bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy. Beat in the egg and vanilla extract, ensuring everything is well mixed. Next, add in the baking soda, salt, and flour, mixing just until combined. Finish by folding in the chocolate chips to create a luscious cookie dough that will complement the brownie layer.
Step 4: Assemble the Brookies
Now it’s time to assemble your Oreo Brookies! Begin by spooning 2-tablespoon drops of cookie dough evenly across the bottom of the prepared baking dish. Fill any gaps with the brownie batter, ensuring you’re creating a delightful mix of both textures. For an extra treat, sprinkle additional Oreo pieces on top to enhance the flavor and presentation.
Step 5: Bake to Perfection
Slide the assembled baking dish into the preheated oven and bake for 35 minutes. Keep a close eye on your creation, checking for doneness at the 25-minute mark. If the top is browning too quickly, cover it loosely with foil to ensure the interior stays moist and gooey.
Step 6: Cool and Serve
Once baked, remove the Oreo Brookies from the oven and allow them to cool in the pan for at least 15-20 minutes. This cooling time helps them set properly. Afterward, cut them into squares to serve. The moment you cut into them, you’ll see the beautiful layers of brownie and cookie, ready to be enjoyed!

Storage Tips for Oreo Brookies
Room Temperature: Store your Oreo Brookies in an airtight container at room temperature for up to 3 days to maintain their delicious texture and flavor.
Fridge: For longer freshness, keep them in the refrigerator for up to a week. Just be sure to seal them well to prevent any unwanted moisture.
Freezer: If you want to save some for later, freeze your Oreo Brookies in a freezer-safe container or wrap them tightly in plastic wrap for up to 3 months.
Reheating: To enjoy, simply thaw at room temperature or microwave for a few seconds to warm them up, bringing back that gooey, fudgy goodness in each bite!
Expert Tips for the Best Oreo Brookies
Quality Matters: Use high-quality chocolate and cocoa powder for a rich, indulgent flavor that elevates your Oreo Brookies.
Cool Before Mixing: Allow the melted chocolate mixture to cool slightly before adding eggs to prevent scrambling; this step ensures a smooth batter.
One Bowl Trick: For convenience, you can mix both batters in one bowl; just make sure to clean the bowl thoroughly in between to maintain flavor integrity.
Bake Wisely: Ovens can vary, so keep an eye on your Oreo Brookies after 30 minutes. Check doneness with a toothpick; it should come out with a few moist crumbs, not wet batter.
Freeze for Future Treats: If you have leftovers (which is rare!), these Brookies freeze well for up to three months. Just thaw before enjoying!

Oreo Brookies Recipe FAQs
How do I choose the right Oreos?
Absolutely! For the best flavor and texture, I recommend using classic Oreos in this recipe. Look for packages that are intact, without any dark spots or signs of damage. If you’re feeling adventurous, try different flavored Oreos, like mint or peanut butter, to add a unique twist to your Brookies!
What is the best way to store leftover Oreo Brookies?
Very easy! Keep your Oreo Brookies in an airtight container at room temperature for up to 3 days. If you’d like them to last longer, refrigerate them for up to a week. Just remember to place parchment paper between layers to prevent sticking!
Can Oreo Brookies be frozen?
Indeed! To freeze your Oreo Brookies, first, allow them to cool completely. Then, cut them into squares and place them in a single layer on a baking sheet to freeze for about 1-2 hours. Once frozen, transfer them to a freezer-safe container, layering them with parchment paper, and store for up to 3 months. When ready to enjoy, just thaw at room temperature or microwave for a few seconds to bring back that yummy gooeyness.
What do I do if the brownie layer is overcooked?
Don’t fret! If you suspect your brownie layer may be overcooked, you can slightly underbake them next time, checking for doneness at the 30-minute mark instead. The center should be just set with a few moist crumbs on the toothpick when poked. If they seem dry after baking, you can also consider adding a scoop of ice cream on top to enhance the dessert experience.
Are there any allergies I need to be aware of while making Oreo Brookies?
For sure! This recipe contains common allergens such as eggs, milk, and wheat. If you’re baking for someone with these allergies, consider using egg substitutes (like applesauce or flaxseed meal), gluten-free flour, and dairy-free chocolate options. Always double-check the labels of your ingredients to ensure safety for those with dietary restrictions.
How long can I keep Oreo Brookies in the fridge?
You can store your Oreo Brookies in the fridge for up to a week! Keep them in an airtight container, and they should retain their delicious taste and texture. Just be sure to let them come to room temperature before serving for the ultimate experience!
