Ingredients
Here’s what you’ll need to bring these spooky treats to life:

1 (10 oz) bag mini marshmallows
3 tablespoons unsalted butter
Green gel food coloring
Candy eyeballs
Semi-sweet chocolate chips or black candy melts (for hair)
Black decorating gel or icing (for scars and mouth)
Optional: mini marshmallows or chocolate chips for Frankenstein “bolts”
Tools You’ll Need
Large pot or microwave-safe bowl
Spatula (greased or silicone)
9×13 inch baking dish
Parchment paper
Sharp knife
Small piping bag or zip-top bag for decorating
Microwave or double boiler (for melting chocolate)
Additions and Substitutions
Cereal: Swap Rice Krispies with cocoa-flavored cereal for a chocolatey twist.

How to Make Frankenstein Rice Krispie Treats
Step 1: Prepare Your Pan
Line a 9×13-inch baking dish with parchment paper and lightly grease it. This makes removing the treats super easy!
Step 2: Make the Base
In a large pot over low heat, melt the butter. Add marshmallows and stir until completely melted and smooth. Remove from heat and stir in a few drops of green food coloring until you reach your desired Frankenstein shade.
Step 3: Add the Cereal
Stir in the Rice Krispies cereal, mixing until everything is fully coated. Press the mixture into your prepared pan, smoothing the top with a greased spatula or wax paper. Let cool for about 20 minutes.
Step 4: Cut Into Rectangles
Once set, lift the mixture from the pan and cut it into even rectangles—these will be Frankenstein’s heads!
Step 5: Decorate
Melt the chocolate chips or candy melts and dip the tops of each rectangle to create “hair.” Immediately add candy eyeballs before the chocolate sets. Use the black decorating gel to draw a mouth and a stitch or scar on the forehead. Add bolts to the sides using mini marshmallows or chocolate chips, if desired.
Step 6: Let Set and Serve
Allow everything to set for about 15–20 minutes or until the chocolate hardens. Then serve and enjoy the smiles!
What to Serve with Frankenstein Rice Krispie Treats
These make the perfect centerpiece for a Halloween dessert table! Serve alongside:
Halloween punch or apple cider
Candy corn or mini chocolate bars
Mummy hot dogs or spooky deviled eggs for a full party spread
Pumpkin cookies or ghost cupcakes for a sweet variety
Tips for Perfect Frankenstein Treats
Grease your spatula: This prevents sticky messes when pressing the cereal mixture.
Use gel food coloring: It gives a bolder color without watering down the mix.
Work quickly: Rice Krispie treats firm up fast—have everything ready before you start.
Cool before decorating: Warm treats can melt your chocolate and icing details.
Storage Instructions
Store your Frankenstein Rice Krispie Treats in an airtight container at room temperature for up to 4 days. If you need to stack them, place a piece of parchment between layers to avoid smudging the decorations.
Avoid refrigerating, as that can make them hard and chewy.

Frequently Asked Questions
Can I make these ahead of time?
Absolutely! These treats can be made 1–2 days in advance and still taste great.
How do I get the color just right?

Can I use store-bought Rice Krispie treats?
Yes! Buy a box, cut them to size, and just decorate if you’re short on time.
Are they gluten-free?
Rice Krispies cereal is not gluten-free due to malt flavoring, but you can substitute with a certified gluten-free crispy rice cereal.
What if I don’t have candy eyeballs?
Get creative! Mini M&Ms, chocolate chips, or hand-piped icing dots can work in a pinch.
