Halloween Oreo Cookie Boo Brownies

These Halloween Oreo Cookie Boo Brownies are the ultimate treat for spooky season celebrations. Each brownie is extra fudgy and decadent, crowned with festive orange Halloween Oreos that melt slightly into the chocolate-studded batter and deliver a playful ghostly crunch. Chilling before serving magically turns these brownies gooier and amps up the festive look and taste.

The first time I experimented with this batch was after my son spotted those seasonal Oreos at the store and insisted they would make brownies even more fun. He was right this combo is now in our permanent October rotation.

Ingredients

• Butter: for a melt in your mouth brownie texture use real unsalted butter and let it soften fully
• Sugar: for sweetening and chew regular granulated sugar works best
• Eggs: for richness and binding choose large eggs at room temperature for the glossiest batter
• Flour: for structure avoid overpacking your cup to keep brownies tender
• Cocoa powder: for deep chocolate flavor opt for Dutch process if possible
• Chocolate chips: for melty pools and added bite use semi sweet or dark for balance
• Crushed and whole Halloween Boo Oreos: the star ingredient these bring seasonal flair and creamy crunch so pick the brightest most intact seasonal packs you can find
• A pinch of salt: to intensify the chocolate never skip it

Instructions

Prepare the Pan:

Line your nine inch metal baking pan snugly with parchment paper so the brownies lift out in one piece making cleanup and slicing much easier

Mix the Brownie Batter:

Combine melted butter with sugar and eggs and whisk vigorously until it looks pale and glossy which gives dense chewy brownies then fold in flour cocoa and a generous handful of chocolate chips being careful not to overmix

Layer the Batter:

Scrape the thick brownie mixture into your prepared pan and use a spatula to smooth the surface fully edge to edge so everything bakes evenly

Decorate with Oreos:

Press whole Halloween Boo Oreos gently on top with the designs facing up then break a few more into chunky pieces and tuck them here and there making sure every bar bakes up with a bit of spooky orange and black peeking through

Bake to Perfection:

Slide the pan into a preheated oven and watch for visual cues rather than just the timer the surface should turn shiny with a few thin cracks and the edges should look set if testing with a toothpick it should come out with a few moist crumbs for a fudgy finish

Cool and Set:

Once baked rest the pan on a rack and let the brownies cool at least two hours in the pan which sets the texture and prevents the Oreos from getting mushy during slicing

Slice Cleanly:

Remove the brownies using the parchment to lift them out then use a large sharp chef knife cleaning it between cuts and pressing down to get those bakery style sharp edges

Optional Chill:

If you want extra chew pop the sliced brownies into the fridge for at least an hour which also deepens the chocolate and Oreo flavors and firms up the texture for perfect snack bars

My favorite part has got to be sneaking the chewy corner pieces with melty chocolate and extra Oreo chunks. Growing up my sister and I always competed for the crispiest edge this recipe sparked that friendly rivalry all over again. I love seeing my kids claim their favorite bars.

Storage Tips

Store sliced brownies in an airtight container at room temperature for up to four days though they rarely last that long in my house. For longer storage freeze individually wrapped bars and thaw as needed for quick treats or lunchbox surprises. If you like chewy brownies keep them chilled and serve straight from the fridge.

Ingredient Substitutions

You can swap in gluten free flour for an allergy friendly treat just measure carefully and check doneness as it may need an extra minute. Try chocolate sandwich cookies if you cannot find the Halloween Oreos just stack your own with colored frosting for fun. Add a handful of white chocolate chips or peanut butter chips for even more flavor twists.

Serving Suggestions

Serve these at a Halloween party with cold milk or alongside a pitcher of spooky punch for kids. Cut brownies into spooky shapes with a cookie cutter for a festive lunchbox snack. Top each brownie with a little whipped cream and Halloween sprinkles for extra flair.

Enjoy making and sharing these gooey festive brownies — they will vanish in a flash and become a new Halloween favorite for your family and friends.
