Ingredients You’ll Need

The beauty of this recipe lies in combining classic brownie ingredients with fun frosting colors and playful decorations. I always recommend using good-quality chocolate—it really makes a difference in the final taste. And for the frosting colors, gel food coloring works best because it won’t thin out your buttercream.

• All-purpose flour: Use fresh flour for a tender crumb.
• Unsweetened cocoa powder: Gives deep chocolate intensity; I prefer Dutch-processed for smoothness.
• Granulated sugar: Balances the cocoa’s bitterness.
• Unsalted butter: Melted for rich flavor and smooth texture.
• Dark chocolate: Melts into the batter for extra fudginess.
• Large eggs: Bind the batter and add moisture; room temperature eggs work best.
• White chocolate chips: Add sweet pockets of creamy contrast.
• Dark chocolate chips: More rich chocolate bites throughout.
• American buttercream frosting: The base for all your colorful frostings.
• Cocoa powder (for frosting): Adds chocolate flavor to the black frosting.
• Milk (for frosting): Helps achieve the right frosting consistency.
• Gel food coloring: Black, teal, yellow, red, purple, pink—use sparingly for vibrant colors without thinning.
• Liquorice roll: Perfect for spooky monster “hair” and “legs.”

Variations

I love to tailor the Monster Mash Halloween Brownies (Kids Recipe) Recipe depending on who’s joining in on the fun. Sometimes, my kids and I get creative with the frosting colors or swap out liquorice for gummy worms to add more “creepy-crawlies.” Feel free to make it your own! Experimenting is half the joy.

• Gluten-Free Version: I once made this with a gluten-free flour blend, and while the texture changes slightly, it still delivers on flavor and festive fun.
• Dairy-Free Option: Substitute butter and chocolate chips with plant-based versions to accommodate allergies without losing that fudgy goodness.
• Spooky Flavor Add-Ins: Add a pinch of cinnamon or espresso powder to deepen the chocolate flavors—my husband’s favorite twist!
• Alternative Decorations: Instead of liquorice, try pretzel sticks for “bones” or edible candy eyes to personalize your monster faces.

How to Make Monster Mash Halloween Brownies (Kids Recipe) Recipe

Step 1: Prep Your Frostings

Before you dive into the brownies, I always start with frosting. Split your American buttercream into seven portions and tint each with the little drops of gel food coloring as instructed. This step helps streamline decorating later — plus, it’s fun to watch vibrant colors come to life. For the black frosting, mix cocoa powder with milk and black gel for that rich, spooky shade. Don’t forget to save a portion plain white to add contrast later on.

Step 2: Mix the Brownie Batter

Heat your oven to 175°C (340°F) fan forced and prep a 32×24 cm baking tin with non-stick spray and parchment paper — this makes lifting the brownies out a breeze. Melt the butter and dark chocolate carefully in the microwave, stirring after each 20-second blast until smooth. Mixing by hand here instead of the microwave’s “defrost” setting prevents burning. Stir in the sugar, then whisk in the eggs one at a time — this keeps your batter silky. Fold in your cocoa powder and flour gently to avoid overmixing, then stir in both white and dark chocolate chips. Yum!

Step 3: Bake and Chill

Pour your batter into the prepared tin and bake for about 30 minutes, or until a pick inserted comes out with moist crumbs (not wet batter). This is key for fudgy brownies. I’ve learned the hard way that overbaking can dry them out, so keep an eye on that timer! After baking, let them chill at room temperature for 1 hour, then pop them in the fridge to set for another hour — this firms the brownies up making them easier to cut and decorate.

Step 4: Cut and Decorate Your Monster Mash

Using a 2½-inch square cookie cutter, cut out 12 frozen brownie squares. Now the magic begins! Pipe your green frosting squares around six brownies for Frankenstein, add little monstrous faces with black, yellow, and red frostings, and finish with liquorice “bolts.” For the mummy brownies, use light yellow frosting in thin lines to create the wrapping look, and spooky eyes with yellow and black frosting. Purple frosting frames three for the spider monsters, complete with red fangs and liquorice “legs.” Last, decorate the remaining by piping a widow’s peak with black, filling in white, and adding vampire eyes and mouth details. Watching each unique monster come to life is a total blast for me and my kids.

How to Serve Monster Mash Halloween Brownies (Kids Recipe) Recipe

Garnishes

I keep things simple but fun by using liquorice sticks—sometimes cutting them into little pieces for “stitches” or long legs. Edible candy eyes from the craft store add an extra spooky touch! If you want some sparkle, a tiny amount of edible glitter dusted over the frosting gives it a subtle magic glow that kids adore.

Side Dishes

These brownies pair perfectly with Halloween-themed fruit like candied apples or a simple glass of cold milk to balance out the rich chocolate. For a party spread, think popcorn tossed with pumpkin spice or pumpkin seed brittle—it complements the monster vibe and satisfies everyone’s sweet tooth.

Creative Ways to Present

When we hosted a Halloween party last year, I arranged the brownies on a black platter lined with fake spider webs and scattered mini plastic spiders around. It made for such a showstopper centerpiece! Wrapping individual brownies in clear bags tied with orange and black ribbons makes a great party favor too. Your kids might love turning the decorating into a contest too—best spooky face wins!

Make Ahead and Storage

Storing Leftovers

Once decorated, I store these Monster Mash Halloween Brownies in an airtight container in the fridge for up to three days. Before serving, I let them sit at room temperature for about 30 minutes to take the chill off and soften the frosting slightly—makes them just like freshly made.

Freezing

I’ve frozen undecorated brownies before with great results—wrap them tightly in plastic wrap and foil. When you’re ready to enjoy, thaw overnight in the fridge, then frost and decorate fresh. This really saves time if you want to prepare in advance without compromising freshness.

Reheating

To warm up leftover brownies without melting the frosting, I place them on a plate, cover lightly with foil, and heat in the microwave for 15-20 seconds. This refreshes the fudgy texture without messing up the decorations. Perfect for a quick after-school snack!
