Step‑by‑Step Instructions for Halloween Oreo Cookie Boo Brownies
Step 1: Prep the Pan
Start by preheating your oven to 350°F (175°C). Then, line a 9×9 inch baking pan with parchment paper, ensuring it hangs over the edges for easy brownie removal later. This little step will help create clean edges and perfect squares for your Halloween Oreo Cookie Boo Brownies!
Step 2: Melt the Butter
In a medium saucepan over low heat, melt ½ cup of butter until completely liquid, stirring occasionally for an even melt. Once melted, remove the saucepan from heat and let the butter cool slightly, ensuring it remains liquid and easy to mix into your gooey batter.
Step 3: Mix Dry Ingredients
In a mixing bowl, whisk together 1 cup of all-purpose flour, 1 cup of sugar (preferably brown), and ½ teaspoon of salt until well combined. This step is crucial as it ensures that your dry ingredients are evenly mixed, which will contribute to the fudgy texture of your Halloween Oreo Cookie Boo Brownies.
Step 4: Combine Wet Ingredients
Slowly pour the melted butter into the mixed dry ingredients, stirring until fully incorporated. Next, crack in 2 room temperature eggs, blending them into the mixture until smooth. This will form the rich, gooey base that makes these brownies irresistibly chewy.
Step 5: Incorporate Dry Ingredients
Gradually fold the dry mixture into the wet mixture using a spatula, mixing until just combined. Be careful not to over-mix, as this can lead to cakey brownies instead of the desired fudgy texture you’ll want with your Halloween Oreo Cookie Boo Brownies.
Step 6: Add Oreos and Chips
Gently fold in 1 cup of crushed Halloween-themed Oreo cookies and ½ cup of chocolate chips until evenly distributed throughout the batter. Make sure to reserve a few whole Oreos for sprinkling on top to add a spooky touch to your brownies!
Step 7: Bake
Pour the brownie batter into the prepared pan, smoothing it out evenly. Sprinkle the reserved whole Oreo pieces on top for that festive flair. Slide the pan into the oven and bake for about 32 minutes, keeping an eye out for the edges to become set and the center still slightly soft—this ensures your Halloween Oreo Cookie Boo Brownies remain fudgy.
Step 8: Cool & Slice
Once baked, remove the brownies from the oven and let them cool in the pan for at least 10-15 minutes. Once cooled, lift the brownies out using the parchment overhang and transfer to a cutting board. Slice into squares, making sure to admire the spooky Oreo designs before serving!
Expert Tips for Halloween Oreo Cookie Boo Brownies
- Avoid Overbaking: Check your brownies at the 30-minute mark. They should be set around the edges but slightly soft in the center for that perfect fudgy texture.
- Use Room Temperature Eggs: This helps the batter mix evenly, ensuring your Halloween Oreo Cookie Boo Brownies turn out super smooth and well-blended.
- Measure Flour Accurately: Too much flour makes brownies cakey. Use a spoon to scoop flour into the measuring cup, then level it off for the best results.
- Reserve Oreo Pieces: Keep some whole Oreos for topping the brownies; this not only adds visual appeal but enhances the festive theme.
- Cool Before Cutting: Allow the brownies to cool adequately in the pan before slicing. This ensures clean cuts and helps maintain their fudgy center.
Make Ahead Options
These Halloween Oreo Cookie Boo Brownies are perfect for meal prep, allowing you to enjoy more time with your loved ones during spooky celebrations. You can prepare the brownie batter up to 24 hours in advance, storing it in an airtight container in the refrigerator to maintain freshness. To do this, simply follow the recipe through Step 6, then cover the bowl tightly and refrigerate. When you’re ready to bake, let the batter sit at room temperature for 15-20 minutes before pouring it into the prepared pan and baking as directed. This way, the brownies will turn out just as delicious and fudgy, ensuring a delightful treat for your gatherings!
Storage Tips for Halloween Oreo Cookie Boo Brownies
Room Temperature: Keep the brownies in an airtight container at room temperature for up to 3 days to maintain their fudgy texture.
Fridge: For longer-lasting freshness, store in the fridge for up to a week—this will preserve the moistness of your Halloween Oreo Cookie Boo Brownies.
Freezer: Wrap the brownies in plastic wrap and then in aluminum foil, storing them in the freezer for up to a month. Enjoy them chilled for a delightful treat!
Reheating: If you’ve frozen the brownies, let them thaw at room temperature or microwave for a few seconds to warm them slightly before indulging.

Halloween Oreo Cookie Boo Brownies Recipe FAQs
What type of Oreos should I use?
Absolutely! I recommend using Halloween-themed Oreos to add that festive touch to your brownies. They not only enhance the flavor with their chocolate crunch but also bring a spooky vibe perfect for the occasion. If you can’t find them, regular Oreos will work just as well.

Then, wrap them again in aluminum foil or place them in a freezer-safe container. They can be stored in the freezer for up to a month. When you’re ready to indulge, simply thaw them at room temperature or microwave them for a few seconds to warm them up!
What should I do if my brownies turn out too cakey?
If your brownies end up cakey, it might be due to overmixing or using too much flour. Next time, be sure to gently fold the ingredients together just until combined. Also, double-check your flour measurement—scoop it into your measuring cup and level it off without packing it down for the right amount.
Are these brownies safe for pets?
Very! While the Halloween Oreo Cookie Boo Brownies are a delightful treat for humans, they aren’t suitable for pets, especially since chocolate can be toxic to dogs and cats. Always keep these scrumptious goodies out of their reach to ensure everyone enjoys them safely!
How can I make these brownies gluten-free?
If you’re looking to make these delicious Halloween Oreo Cookie Boo Brownies gluten-free, simply substitute regular Oreos with gluten-free Oreos and use a gluten-free all-purpose flour blend in place of the all-purpose flour. This way, everyone can indulge in the spooky fun without worry!
