Essential Tools for Your Brownie creations
Before you start your spooky baking adventure, having the right tools and ingredients will make the entire process smoother and more fun. These key items will help you create perfect Halloween brownies every time.
- The Perfect Pan: A reliable pan is the foundation of any great brownie. We love the Wilton Perfect Results 9×13 Inch Brownie Pan because its non-stick surface ensures your brownies come out cleanly every time, making them easy to cut and decorate.
- A Fudgy Foundation: While homemade is great, a high-quality mix saves time and delivers consistent results. Ghirardelli Double Chocolate Brownie Mix is our go-to for an intensely rich and chewy base that holds up well to frosting and decorations.
- Creating Spooky Shapes: For perfectly uniform brownie bites, use a Wilton Halloween Metal Cookie Cutter Set. The ghost, pumpkin, and bat shapes are perfect for cutting out cooled brownies before decorating.
- Bringing Treats to Life: The easiest way to add personality to your creations is with edible eyes. A container of Wilton Edible Candy Eyeballs is a must-have for instantly turning your brownies into cute monsters, mummies, and spiders.
- For Ghoulish Details: To draw fine lines, webs, or faces, a set of Wilton Decorating Icing Pouches in black and white is incredibly useful. The attached tips give you great control for detailed work.
- Spooky Sprinkles: A festive finishing touch can make all the difference. The Wilton Halloween Sprinkles Assortment offers a fun mix of bats, ghosts, and colorful jimmies to add texture and flair to your brownies.
With these tools in your kitchen, you’re all set to bake and decorate a batch of truly unforgettable treats.
The Perfect Base: Your Ultimate Fudgy Brownie Recipe
Every great Halloween brownie starts with a fantastic base. You can use your favorite box mix (we highly recommend the {Ghirardelli Double Chocolate Brownie Mix}) or this simple, foolproof from-scratch recipe that guarantees rich, chewy results.
Ingredients:
- 1 cup (2 sticks) unsalted butter, melted
- 2 cups granulated sugar
- 4 large eggs
- 1 teaspoon vanilla extract
- 1 cup all-purpose flour
- 3/4 cup unsweetened cocoa powder
- 1/2 teaspoon baking powder
- 1/4 teaspoon salt
- 1 cup semi-sweet chocolate chips (optional, for extra fudginess)
Instructions:
- Prep Your Pan: Preheat your oven to 350°F (175°C). Grease and flour your {Wilton Perfect Results 9×13 Inch Brownie Pan}, or line it with parchment paper, leaving an overhang on the sides to easily lift the brownies out later.
- Mix Wet Ingredients: In a large bowl, whisk together the melted butter and granulated sugar until well combined. Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
- Combine Dry Ingredients: In a separate medium bowl, whisk together the flour, cocoa powder, baking powder, and salt.
- Mix Together: Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix! Overmixing can lead to tough, cakey brownies. Gently fold in the chocolate chips if you’re using them.
- Bake: Pour the batter into your prepared pan and spread it evenly. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out with moist crumbs attached, but not wet batter.
- Cool Completely: This is the most important step for decorating! Let the brownies cool completely in the pan on a wire rack. If you try to cut or decorate warm brownies, they will fall apart. For best results, let them cool for at least 2 hours.

6 Spooktacular Halloween Brownie Decorating Ideas
Now that you have your perfectly cooled brownies, it’s time for the fun part! Here are six simple yet impressive ways to transform them into spooky masterpieces.
1. Mummy Brownies
These might look detailed, but they are one of the easiest and most popular designs. The messy “bandages” are very forgiving for beginners.
How to decorate:
- Cut your cooled brownies into rectangles.
- Melt white candy melts or prepare a batch of white buttercream frosting.
- Place some of the melted candy or frosting into a piping bag with a small, flat tip, or use a plastic sandwich bag with a tiny corner snipped off.
- Drizzle the white icing back and forth across the brownie, creating layered, overlapping strips that look like mummy bandages. Leave a small gap open for the eyes.
- Before the icing sets, place two {Wilton Edible Candy Eyeballs} in the gap. Let the icing set completely before serving.

2. Graveyard Brownies
Turn your entire pan of brownies into a spooky cemetery scene. This is a fantastic centerpiece dessert that’s great for a party.
How to decorate:
- Frost the entire pan of cooled brownies with a layer of chocolate frosting.
- Crush a package of Oreo or other chocolate sandwich cookies into fine crumbs. Sprinkle these “dirt” crumbs generously over the frosting.
- Use oblong cookies, such as Milano cookies or shortbread fingers, as “tombstones.” Use a {Wilton Decorating Icing Pouch} with black icing to write “RIP” or draw a cross on each cookie.
- Press the cookie tombstones into the brownies at various angles to create the graveyard scene.
- For extra flair, add gummy worms crawling out of the “dirt” or pipe little white frosting ghosts peeking out from behind the tombstones. You can even crumble some green-colored coconut flakes for “moss.”

3. Spiderweb Brownies
This elegant and spooky design is incredibly simple to create and looks very impressive. You can make these on individual brownies or across a whole pan.
How to decorate:
- Cut your brownies into squares or circles.
- Frost each brownie with a layer of dark chocolate frosting.
- Using a Wilton Decorating Icing Pouch with white icing (or melted white chocolate), pipe 3-4 concentric circles on top of the chocolate frosting.
- Take a toothpick and, starting from the center circle, drag the tip outwards to the edge of the brownie.
- Wipe the toothpick clean and repeat this action every inch or so around the brownie to create the web effect.
- For an extra touch, you can create a spider in the corner using a brown M&M for the body and piped chocolate legs.

4. Ghost-Topped Brownies
These adorable ghosts are a simple and cute way to decorate. This method uses marshmallows for a fun, 3D effect.
How to decorate:
- Cut your brownies into squares.
- Place one large marshmallow on top of each brownie.
- Put the brownies on a microwave-safe plate and microwave for just 5-10 seconds. The marshmallow will puff up and get soft.
- Remove from the microwave and, while the marshmallow is still warm and pliable, use your fingers or a spoon to gently stretch and shape it into a ghostly form.
- Alternatively, you can drape a piece of white fondant over the brownie.
- Once the ghost shape is set, use a black edible marker or a tiny dab of black icing to draw on two eyes and a spooky, open mouth.

5. Monster Mash Brownies
This is the perfect design for letting your creativity (and the kids’ creativity) run wild. There are no rules for these monstrously fun Halloween brownies.
How to decorate:
- Frost your brownies with brightly colored frosting—think neon green, electric purple, or bright orange. You can use a mix of colors and swirl them together for a tie-dye effect.
- While the frosting is still wet, go crazy with decorations. Cover them in a festive Wilton Halloween Sprinkles Assortment.
- Give your monsters personality by adding one, two, three, or even a whole cluster of Wilton Edible Candy Eyeballs.
- You can use different colors of icing to pipe on silly hair, pointy horns, or a goofy, toothy grin. Every brownie can be a unique monster!

6. Pumpkin Patch Brownies
Celebrate the harvest season with these cute and easy pumpkin patch brownies. They are less spooky and more festive, perfect for any fall gathering.
How to decorate:
- Frost your brownies with chocolate frosting and sprinkle with crushed chocolate cookies to create “dirt.”
- You’ll need pumpkin-shaped candies, like Mellowcreme Pumpkins, which are widely available in the fall.
- Arrange the pumpkin candies on top of the brownies to create your “patch.”
- For the vines, use a Wilton Decorating Icing Pouch with green icing to pipe squiggly lines connecting the pumpkins. You can even add a few little leaves coming off the vines.
