- 1 batch Oreo Brownies by Baker by Nature: The fudgy, decadent base loaded with Oreo chunks that sets the stage for this treat.

- Large chef’s knife: Essential for neatly slicing the brownies to showcase the beautiful layers and Oreo surprise inside.
How to Make Halloween Oreo Cookie Boo Brownies
Step 1: Prepare the Oreo Brownie Base
Start by mixing up your favorite batch of Oreo brownies using the recipe from Baker by Nature. The batter is rich and fudgy and includes chunks of regular Oreos, which add that perfect cookie crunch throughout. Pour it into your prepared baking pan, spreading it evenly to ensure consistent baking.
Step 2: Add the Halloween Boo Oreos
Once the brownie batter is ready and before baking, gently press a layer of Halloween Boo Oreos on top of the batter. These ghost-themed cookies turn each square into a festive surprise. The contrast of the dark cookie with the white creamy filling makes every piece uniquely eye-catching, adding not only flavor but a playful vibe.
Step 3: Bake to Perfection
Pop the pan into your preheated oven and bake according to the brownie recipe’s instructions. The brownies should set while the Oreos maintain their crispness and creamy center, resulting in a fantastic textural balance. Keep an eye on the edges to avoid overbaking so that fudgy texture is just right.
Step 4: Slice and Serve
After baking, allow your Halloween Oreo Cookie Boo Brownies to cool completely. Using your large chef’s knife, slice the brownies into neat squares, ensuring each piece contains at least one Boo Oreo for maximum spooky impact. Clean cuts help keep the layers intact and showcase the delightful Oreo surprises inside.
How to Serve Halloween Oreo Cookie Boo Brownies

Garnishes
If you want to glam up your presentation, consider dusting your brownies with a light sprinkle of powdered sugar or some edible glitter for that magical Halloween shimmer. Mini white chocolate chips or ghost-shaped sprinkles can also elevate the festive feel without overpowering the brownie itself.
Side Dishes
These brownies shine brightest on their own but pairing them with a scoop of vanilla ice cream or a drizzle of caramel sauce creates a decadent experience. For a less sweet contrast, serve alongside a cup of strong coffee or steaming hot chocolate with marshmallows to keep the Halloween spirit alive.
Creative Ways to Present
For a memorable Halloween party, arrange your Halloween Oreo Cookie Boo Brownies on a themed platter surrounded by mini pumpkins, fake cobwebs, or autumn leaves. Wrapping individual squares in clear cellophane and tying them with orange and black ribbon makes for a perfect take-home treat your guests will appreciate.
Make Ahead and Storage
Storing Leftovers
These brownies stay moist and delicious when stored in an airtight container at room temperature for up to four days. Make sure to separate layers with parchment paper to prevent sticking and keep those Halloween Boo Oreos crisp.
Freezing
If you want to make these brownies ahead of time, they freeze beautifully. Wrap them tightly in plastic wrap and place in a freezer-safe container for up to three months. Thaw overnight in the fridge before slicing to preserve texture and flavor.
Reheating
To refresh your brownies, warm a slice in the microwave for about 10-15 seconds. This enhances their fudgy texture and makes the creamier parts of the Oreos delightfully melty. Avoid overheating to keep the cookies from getting too soft.
FAQs
Can I substitute the Halloween Boo Oreos with regular Oreos?
Absolutely! While Halloween Boo Oreos add a fun festive touch, regular Oreos work perfectly well and still provide that classic cookie crunch and creamy filling to complement the brownies.
Do I need to bake the Oreos on top of the brownie batter?
Pressing the Oreos onto the uncooked batter before baking helps them meld with the brownies without losing their crunch. It also enhances the visual appeal and ensures every square has a delicious Oreo surprise.
How can I make my brownies fudgier?
To get extra fudgy brownies, avoid overbaking and consider adding an extra egg yolk or a bit of melted butter to the batter. Using high-quality chocolate and not overmixing helps maintain that rich, dense texture.
Can I make these brownies nut-free?
Yes! This recipe doesn’t call for nuts, but make sure your brownies and Oreos are processed in nut-free facilities if you have allergies. Double-check ingredient labels for safety.
What’s the best way to cut brownies so the Oreos don’t crumble?
Use a sharp, large chef’s knife and clean it between cuts. Chilling the brownies before slicing helps firm them up, making it easier to achieve clean, beautiful squares without breaking the Oreos.
