Can I use a boxed brownie mix instead of homemade?

Yes! If you're short on time, a boxed brownie mix works perfectly as a base. Just stir in crushed Halloween Oreos and chocolate chips, and press a few whole Oreos on top before baking. To get that homemade feel, you can add a splash of vanilla extract or espresso powder to deepen the flavor.

Where can I buy Halloween-themed Oreos?

You’ll find Halloween Oreos in most major grocery stores, usually starting in early September. They’re also available online through retailers like Amazon, Walmart, and Target. Be sure to grab a few packs—they sell out fast during spooky season!

How do I cut brownies without smudging the Oreo designs?

Let the brownies cool completely before cutting. For extra clean lines, refrigerate them for 30 minutes. Then use a large, sharp knife—press down and lift up instead of sawing. Wipe the blade between cuts to keep those festive Oreo tops looking picture-perfect.

Can I make these brownies ahead of time?

Absolutely. These brownies keep well for up to a week in the fridge or two months in the freezer. You can even prepare the batter ahead of time and store it chilled or frozen until ready to bake.

What’s the best way to serve these at a Halloween party?

Slice them into small squares, wrap them individually in parchment or cellophane, or add them to a spooky dessert board. They're also perfect for Halloween lunchboxes, potlucks, or as gifts with a haunted twist.

Cook Mode Prevent your screen from going dark

Instructions

Preheat oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving overhang on the sides.
In a large bowl, whisk melted butter with both sugars until smooth.
Beat in eggs one at a time, then stir in vanilla extract.
Sift in cocoa powder, flour, and salt. Stir until just combined.
Fold in chocolate chips and chopped Oreos.
Pour batter into the prepared pan and smooth the top with a spatula.
Arrange whole Halloween Oreos on top, print side up.
Bake for 30–35 minutes or until the edges are set and the top is shiny with a few cracks.
Cool completely in the pan. For clean slices, refrigerate for 30 minutes before cutting.
Slice into squares using a sharp knife, wiping between cuts.

Notes

Do not overbake—check a few spots with a toothpick for doneness.
Use parchment paper for easy lifting and cleaner cuts.
Try chilling brownies for extra chewiness and intensified texture.
Place whole Oreos with spooky designs facing up before baking.
Wipe the knife after each slice for neat brownie squares.
