Ingredients
This recipe uses simple ingredients to create a festive, flavorful treat. Here’s what you’ll need, why each one matters, and some substitutions:
Marshmallows (two 12-ounce bags): The sticky, sweet base that binds the cereal and creates the spooky web topping.
Substitution: Use marshmallow fluff (about 3 cups per bag) or vegan marshmallows for a plant-based option.
Unsalted Butter (6 tablespoons): Adds richness and helps melt the marshmallows smoothly.
Substitution: Use margarine or vegan butter for a dairy-free version.
Green Gel Food Coloring: Tints half the mixture a vibrant, spooky green.
Substitution: Use natural green food coloring (like spirulina) or another color like orange.
Purple Gel Food Coloring: Creates a contrasting, eerie purple layer.
Substitution: Use natural purple food coloring (like beet juice) or swap for blue or black.
Crispy Rice Cereal (9 cups): Provides the signature crunch and structure.
Substitution: Use gluten-free crispy rice cereal or puffed quinoa for a different texture.
Semisweet Chocolate Chips (1/2 cup): Melted to pipe spider legs for decoration.
Substitution: Use milk chocolate, white chocolate, or candy melts.
Chocolate-Covered Peanuts or Black/Orange Jellybeans: Form the spider bodies for a cute, spooky touch.
Substitution: Use chocolate candies, gummy candies, or raisins.
Why These Ingredients Matter
The marshmallows and cereal create a light, crunchy treat that’s easy to eat, while the butter adds a touch of richness. The food coloring and candy decorations make these treats visually striking for Halloween, and the ingredients are affordable and easy to find. While indulgent, the small portion size (9 servings) makes them a fun treat, and you can swap ingredients for dietary needs, keeping the recipe versatile.
Instructions
Step 1: Prep the Pan
Line a 9-by-13-inch baking dish with foil, leaving an inch or two of overhang on the sides.
Spray the foil with nonstick cooking spray to prevent sticking.
Tip: Use enough foil to create a work surface for decorating later.
Step 2: Melt the Marshmallows
Divide 1.5 bags of marshmallows (about 18 ounces) evenly between two large microwave-safe bowls (about 9 ounces per bowl).
Add 3 tablespoons of butter to each bowl.
Microwave one bowl for about 45 seconds until the marshmallows start to melt. Stir well, then microwave for another 30 seconds until completely melted.
Add green gel food coloring to the first bowl and stir until vibrant and even.
Repeat the melting process with the second bowl, tinting it with purple gel food coloring.
Tip: Stir in small amounts of food coloring at first—you can always add more for a bolder hue.
Step 3: Mix in the Cereal
Add 4.5 cups of crispy rice cereal to the green marshmallow mixture and stir until fully coated.
Repeat with the purple marshmallow mixture and the remaining 4.5 cups of cereal.
Tip: Work quickly while the marshmallows are warm to make mixing easier.
Step 4: Form the Layers
Grease your hands with cooking spray or wear disposable gloves to prevent sticking.
Using one hand for green and one for purple, scoop blobs of each color mixture into the prepared pan, randomly distributing them to create a mottled, layered effect.
Once all the cereal is in the pan, press the mixture evenly to smooth the top.
Tip: Don’t overmix the colors in the pan to keep the green and purple swirls distinct.
Step 5: Cool and Cut
Let the treats cool and set completely, at least 1 hour, at room temperature.
Use the foil overhang to lift the treats from the pan. Peel back the foil edges to create a flat work surface.
Trim the edges with a serrated knife for neat squares, if desired, and cut into 9 rectangles.
Tip: Separate the cut treats slightly on the foil to make decorating easier.
Step 6: Make the Marshmallow Web
Place the remaining half bag of marshmallows (about 6 ounces) in a large microwave-safe bowl.
Microwave for 45 seconds, stir, then microwave for another 30 seconds until fully melted. Let cool slightly until just warm to the touch.
Wear disposable gloves, grab a handful of melted marshmallows, and rub between your hands. Pull your hands apart to create long, web-like strings.
Drape the strings over the treats in different directions to form a spider web pattern, scooping more marshmallows as needed.
Tip: Work quickly—the marshmallow hardens fast. If it gets too stiff, microwave for 10 seconds to soften.
Step 7: Add the Spiders
Melt 1/2 cup of semisweet chocolate chips in a double boiler or microwave at 50% power in 30-second intervals, stirring until smooth.
Transfer the melted chocolate to a piping bag with a small, plain tip (or a zip-top bag with a tiny corner snipped off).
Pipe 8 spider legs on each treat, forming a starburst shape.
Place a halved chocolate-covered peanut or jellybean, cut side down, in the center of the legs to create a spider body.
Tip: Practice piping the legs on a plate first to get the hang of it.
