Halloween desserts don’t always have to be complicated or over-the-top to make an impression. Sometimes, the simplest treats get the biggest reactions—like these Halloween Brownies. Picture fudgy squares of chocolate bliss transformed into spooky brownies with white chocolate spiderwebs and candy-eyed mummies. They’re the kind of Halloween inspired desserts that work just as well for a family movie night as they do for a full-on Halloween buffet.
I first made these during a neighborhood Halloween party, and the kids couldn’t stop giggling over the “mummy faces” staring back at them. Parents loved that it was a classic brownie base with just a playful twist. Whether you’re planning a witch themed snack spread, looking for spooky season recipes, or just need something quick to fill a Halloween traybake, this recipe brings fun, flavor, and festivity in every bite.
Halloween Brownies

Step-by-Step Instructions
Step 1: Prepare the pan
Preheat the oven to 350°F (175°C). Line a 9×9-inch baking pan with parchment paper, leaving a bit hanging over the edges for easy lifting later. Lightly grease for extra non-stick assurance.
Step 2: Bake the brownies
Prepare the brownie batter according to the package directions. Pour into the lined pan and bake as directed. Once done, allow the brownies to cool completely in the pan.
Step 3: Slice and set up
Lift the cooled brownies from the pan using the parchment paper. Place on a cutting board and slice into even squares—usually 9–12 pieces.
Step 4: Melt the white chocolate
In a microwave-safe bowl, melt the white chocolate in 30-second bursts, stirring in between until smooth.
Step 5: Decorate with spooky flair
- Transfer the melted chocolate into a piping bag (or zip-top bag with a small corner snipped).
- Pipe spiderwebs across some brownies.
- Pipe mummy “bandages” across others, then immediately press candy eyes into place.
Step 6: Set and serve
Allow the chocolate decorations to firm up at room temperature or refrigerate for a few minutes. Plate them up on a Halloween traybake platter, and watch the magic happen.
Variations, Storage & Serving Ideas
- Vampire Snacks: Drizzle red candy melts alongside the webs for a gory twist.
- Witch Themed Snacks: Top with green frosting hats or candy witches’ brooms.
- Halloween Buffet Ready: Arrange them with Eyeball Jello Shots and Pumpkin Scones for a dessert spread that wows.
- Storage: Keep in an airtight container at room temperature for up to 3 days. Refrigerate for up to 5.
For a crowd, consider doubling the recipe and using a 9×13-inch pan for an even bigger Halloween bakery treat batch.
