Gather Your Ghastly Goodies: Ingredients You’ll Need
Creating these delightful monster brownies requires a mix of pantry staples and a few fun decorative elements. While the full, printable recipe with exact measurements is available at the end of this post, here’s a general overview of the key components you’ll need to conjure up your own batch of Halloween treats:
Ingredient Insight & Creative Substitution Ideas
Let’s dive deeper into the ingredients and explore some fantastic alternatives to make your monster brownies truly unique and tailored to your taste!
- BROWNIES: Our recipe prioritizes ease, so starting with an 18-ounce box brownie mix (like the Ghirardelli double chocolate mix we love for its rich flavor) is highly recommended. It guarantees a perfectly moist and fudgy base every time, leaving you more energy for the artistic part. However, if you’re a purist or have a go-to recipe, feel free to prepare your favorite homemade fudge brownies from scratch. Just ensure they are fully cooled before decorating!
- EYES: The charmingly quirky eyeballs are crafted from white chocolate-dipped Cheerios, adorned with a mini chocolate chip pupil. This method allows for a custom, slightly irregular look that adds to their monster charm. For an even quicker decorating process, readily available candy eyeballs are an excellent substitute. They come in various sizes, offering even more character options for your monsters!
- ICING: To streamline the decorating, we opt for vibrant, pre-packaged cookie icing, often found in your grocery store’s baking aisle. This royal icing-style frosting sets beautifully, providing a firm base for your decorations. If you’re feeling adventurous and want to mix your own colors, white cookie icing can be tinted with gel food coloring. For intricate details like hair, expressive eyebrows, or goofy smiles, black decorator gel is your best friend, offering precision and rich color. While royal icing is preferred for its setting properties, you could also use a slightly thinned store-bought buttercream frosting if you don’t mind a softer finish.
- DECORATIONS: This is where the real fun begins! Think outside the box and let your imagination run wild. We used a variety of colorful cereals like Cocoa Puffs, Cheerios, Captain Crunch All Berries, and Oreo Puffs for unique textures and patterns. But the possibilities are endless! Consider adding:
- Pretzels: For arms, legs, or horns.
- Mini Cookies: Crushed or whole for texture.
- Assorted Candies: Gummy worms, candy corn, mini chocolate candies, M&Ms, or even colorful sprinkles can create fantastic monster features.
- Nuts: Chopped nuts can add a craggier, more fearsome look.
- Mini Marshmallows: Cut in half for teeth or stacked for eyes.
Encourage your little bakers to experiment with different combinations to create a truly diverse cast of monster characters!
Crafting Your Creepy-Cute Creations: How to Make Monster Brownies
These detailed step-by-step instructions and accompanying photos are designed to guide you through the process of creating these delightful monster brownies. For the full, printable version of this recipe, complete with precise measurements and instructions, please refer to the recipe card at the bottom of this page.
- Prepare Your Brownie Canvas: Begin by preparing your brownie mix according to the package directions. Bake as instructed and, once done, allow the brownies to cool completely. For exceptionally clean and sharp cuts, I recommend chilling your baked brownies in the refrigerator for at least an hour. Once cooled, carefully slice off the slightly firmer edges. Then, cut your brownies into an assortment of rectangles and squares. Don’t discard any odd-shaped leftovers – these can be imaginatively cut into triangles or other irregular shapes to add character to your monster collection!
Whipping Up Wicked Eyeballs
Crafting the edible eyeballs is a crucial step to tackle early, as they require sufficient time to dry and set. This ensures they maintain their shape and stick firmly to your frosted brownies.
- Create the Glaze: In a small bowl, combine about ¼ cup of powdered sugar. Gradually add milk, starting with approximately one teaspoon and adding a few drops at a time, stirring continuously. Your goal is a thick yet dippable glaze consistency, similar to slightly runny white glue. It should be thick enough to coat the cereal but thin enough to drip off excess easily.
-
Mixing powdered sugar and milk to achieve the perfect glaze consistency for your monster eyeballs. Dip the Cereal: Gently drop a few Cheerios into the prepared glaze, ensuring they are fully coated. Using a spoon, carefully lift each glazed Cheerio, allowing any excess glaze to drip off. Place the coated Cheerios onto a cookie sheet lined with wax paper or parchment paper.
Ensuring each Cheerio is perfectly coated in the sweet glaze. Carefully placing the glazed Cheerios on wax paper to dry. -
Add the Pupils: While the glaze is still wet, place a mini chocolate chip, upside down (flat side up), directly into the center of each glazed Cheerio. Gently press the mini chip to secure it. This creates the pupil for your monster’s eye. Set the cookie sheet aside in a cool, dry place to allow the glaze to fully harden, which may take an hour or more depending on humidity.

Bringing Your Monsters to Life: Decorate the Brownies
Now for the most exciting part – transforming your brownies into a cast of zany, spooky, and sweet monsters!
- Frost Your Brownies: Using an offset icing spatula, a rubber spatula, or even the back of a spoon, generously spread your chosen cookie icing over the top of each cooled brownie. Don’t worry about perfection; uneven swirls and textures can add to the monster’s charm!
- Add Polka Dots & Textures: While the frosting is still fresh and wet, gently press an assortment of colorful cereals into the surface. These will serve as your monsters’ unique polka dots, scales, or textured skin. Working quickly ensures that the decorations adhere firmly to the moist icing.
-
Place Eyeballs & Features: Carefully lift your pre-made edible eyeballs from the wax paper using a toothpick. Gently press them onto the frosted brownies in various configurations – single eyes, multiple eyes, or even off-kilter eyes for a truly monstrous look. Now, get creative with your decorator gel! Use pretzel sticks to create quirky arms, legs, or horns. With the black decorator gel, draw on expressive eyebrows, wide grins, fanged mouths, or wild, wispy hair. Red decorator gel can add bloodshot details to eyes or gruesome mouths. Each monster should have its own personality!

Frequently Asked Questions & Expert Tips for Monster Brownie Mastery
Here are some common questions and valuable tips to help you perfect your monster brownie creations:
If your local store doesn’t carry the exact pre-packaged royal icing colors you’re looking for, don’t despair! You can easily purchase white cookie icing and tint it yourself with a few drops of gel food coloring. Gel colors are highly concentrated and produce vibrant hues without thinning the icing too much. However, be aware that pre-colored icings from the bag often dry with a smoother, more consistent finish, so if you can find your desired colors, that’s generally the easiest route. As an alternative, for a softer, non-hardening frosting, you can gently warm up a tub of store-bought buttercream frosting in the microwave until it’s thin enough to spread. This method is quick and easy, but remember the frosting won’t set firm, which might affect packaging. For inspiration, check out our easy decorated sugar cookies recipe which uses a similar technique.
To keep your monster brownies fresh and fabulous, store them in an airtight container at room temperature. To prevent the decorations from sticking or getting smudged, it’s best to separate layers of brownies with parchment paper. Properly stored, these delightful treats will stay fresh and delicious for up to 4 days. If your frosting is the non-hardening type, be extra careful when stacking or consider storing them in a single layer if possible.
Absolutely! You can bake the brownies a day or two in advance. Once cooled, wrap them tightly in plastic wrap and store at room temperature. For optimal cutting and decorating, it’s actually beneficial to chill the baked brownies in the refrigerator for at least an hour before slicing and frosting. This makes for cleaner edges and a firmer canvas for your monster creations.
No problem at all! The beauty of monster brownies is their versatility. Feel free to use any cereals you have on hand that offer interesting shapes, colors, or textures. Think about crushed cornflakes for a spiky monster, pretzel pieces for limbs, or even tiny marshmallows for fuzzy textures. The goal is to be creative and use what you love or what’s readily available!
Serving Your Spooktacular Sweets
Monster brownies are incredibly versatile, not just for eating but also for gifting and party presentations. Imagine wrapping these adorable, ghoulish delights in clear cellophane gift baggies and tying them with vibrant Halloween ribbons. They make fantastic, personalized party favors that guests will adore taking home!
If you’ve used royal icing (like the Betty Crocker icing mentioned in the recipe card), which hardens when dry, wrapping them in cellophane works perfectly. However, if you’ve used decorator gel for the fine details, remember that gel typically does not harden completely. In such cases, or if you prefer a more formal presentation, consider placing each brownie in a small pastry box to protect those delicate monster features. For a party display, arrange your diverse collection of monsters on a festive platter adorned with spiderwebs, plastic spiders, or autumn leaves to create a truly immersive Halloween experience.

- Pretzel sticks
- Red and black decorator gel

Things You’ll Need

Offset icing spatula or spoon
-
Toothpicks
Before You Begin
- The nutrition count on each individual brownie will vary greatly depending upon the amount of decorations you add and how large or small you cut your brownie. The nutrition facts listed here only includes a standard sized baked brownie, please refer to your individual ingredients for more accurate nutrition information.
- The number of brownies you yield will again vary depending upon the shapes you cut them in to. When I make these, I like to use two brownie mixes so I have more wiggle room to be creative.
- You can use any prepackaged cookie icing such as Great Value, Wilton, or Betty Crocker icing. It should be royal icing, not regular frosting (though you can use regular frosting if preferred).
Instructions
- Prepare your brownies and allow them to cool. I refrigerated mine so that I could get nice clean cuts. When your brownies are ready to be cut, slice off the edges. Cut the brownies into different sized rectangles and squares. I cut some of the odd shaped leftovers into triangles too.
Make the Eyes
- It’s important to do this step first (after preparing the brownies) to allow adequate time for the glaze to dry. To make the eyes you’ll need any variety of Cheerios, some mini chocolate chips, powdered sugar and a little milk. Place the powdered sugar into a small bowl. Using a spoon, stir in some milk, a little bit at a time, until the consistency is good enough for dipping. Start with about a teaspoon and add a couple drops at a time until you get it where you want it.
- Drop a few Cheerios into the glaze coating the cereal. Use a spoon to lift the cereal out of the glaze and place on a wax paper lined cookie sheet.
- Place a mini chocolate chip, upside down, in the center of each glazed Cheerio. Gently press the mini chip to set. Set aside.
Decorate
- Use an icing spatula, a rubber spatula, or the back of a spoon to spread the royal icing over the top of each brownie.
- Gently press assorted cereals into the frosted brownies for the monsters’ polka dots. Do so while the frosting is still wet so that your decorations stick.
- Lift the eyes from the waxed paper using a toothpick and gently press onto the frosted brownie. You can use pretzel sticks for arms and legs, and add eyebrows, mouths and hair using decorator gel.
Expert Tips & FAQs
- Store your brownies in an air-tight container, separated by layers of parchment paper. Keep at room temperature for up to 4 days.

The recipes on this blog are tested with a conventional gas oven and gas stovetop. It’s important to note that some ovens, especially as they age, can cook and bake inconsistently. Using an inexpensive oven thermometer can assure you that your oven is truly heating to the proper temperature. If you use a toaster oven or countertop oven, please keep in mind that they may not distribute heat the same as a conventional full sized oven and you may need to adjust your cooking/baking times. In the case of recipes made with a pressure cooker, air fryer, slow cooker, or other appliance, a link to the appliances we use is listed within each respective recipe. For baking recipes where measurements are given by weight, please note that results may not be the same if cups are used instead, and we can’t guarantee success with that method.
