Ingredients for Frankenstein Rice Krispie Treats

This recipe makes about 12 monster treats. You’ll need:

• 3 tablespoons unsalted butter
• 1 (10-ounce) bag mini marshmallows
• 6 cups Rice Krispies cereal

Step-by-Step Instructions for Spooky Frankenstein Rice Krispies

Step 1: Make the Base Treats

In a large saucepan, melt the butter over medium heat. Add mini marshmallows and stir continuously until fully melted and smooth. Remove from heat.

Step 2: Add the Monster Hue

Stir in green food coloring until you reach your desired Frankenstein shade. Mix thoroughly to ensure even coloring.

Step 3: Combine with Cereal

Add the Rice Krispies cereal and stir gently to combine with the marshmallow mixture. Be careful not to crush the cereal too much.

Step 4: Shape and Cool

Transfer the mixture to a greased or parchment-lined 9×13-inch pan. Press down gently with a greased spatula or wax paper. Let it cool completely.

Step 5: Cut and Stick

Once set, cut the treats into rectangles. You can insert popsicle sticks at the bottom for a cute “Frankenstein on a stick” effect.

Step 6: Add the Hair and Eyes

Melt the chocolate chips in the microwave in 30-second intervals, stirring between each. Dip the top third of each treat into the melted chocolate to create Frankenstein’s hair. Place two candy eyeballs on the chocolate section before it sets.

Step 7: Draw the Face

Once the chocolate has hardened, use black gel or edible marker to draw scars, smiles, and monster frowns. Have fun with the expressions!

Frankenstein Rice Krispie Treats can easily be made ahead and stored for convenience:

Serving and Display Ideas for Halloween Party Treats

Presentation makes all the difference at a Halloween party:

• Wrap in individual treat bags and add printable tags for classroom parties
• Stand them upright in a carved pumpkin bowl
• Add edible “graveyard dirt” (cookie crumbs) for a spooky effect

Common Mistakes to Avoid When Making Spooky Snacks

• Overheating marshmallows can cause treats to harden too quickly
• Using too much food coloring can leave a bitter aftertaste
• Not pressing the mixture evenly can cause uneven sizes and shapes
• Applying gel on wet chocolate causes it to smear

For a cleaner alternative to decorating, try using Vegan Halloween Cupcakes with Chocolate Skulls for pre-piped toppers.
