Ingredients
- Rice Krispie Cereal – Any brand of puffed rice cereal will work.
- Mini Marshmallows – These melt more quickly and evenly than large marshmallows. If using large ones, just cut them into pieces first.
- Butter – Unsalted butter works best so you can control the flavor.
- Green Candy Melts – These give the signature Frankenstein look. If you can’t find green candy melts, use white candy melts and add green food coloring.
- Edible Googly Eyes – Available in the baking aisle or craft stores. If you don’t have them, small chocolate chips or candy dots work as substitutes.
- Black Icing – Use decorating icing in a piping tube for easy control. You can also use melted chocolate or black candy melts piped from a small plastic bag.
- Black Sprinkles – These create Frankenstein’s “hair.” Chocolate sprinkles or crushed chocolate cookies can be used if you don’t have black sprinkles.

Instructions
Step 1: Grease or spray a 9x13 glass baking dish. (If using a metal baking sheet, I like to line it with parchment paper.) Over medium heat, melt the butter in a large pot. Add the marshmallows to the pot and stir until melted. Add in the rice krispie cereal and stir until the cereal is fully mixed with the marshmallows.
Step 2: Transfer the rice krispie mixture into the 9x13 dish and press down until the top is flat. Allow the rice krispie treats to set for 30 minutes.
Step 3: Remove the rice krispie treats from the baking dish and cut into 12 even sized rectangles.
Step 4: Melt the green and black candy melts according to the package. It can be done in a double boiler or microwave. Dip the top of each rice krispie treat into the melted green candy.
Step 5: Next dip the top of the green part of the treat into the sprinkles to make it look like hair.
Step 6: Add two candy eyeballs for the eyes then use the black icing to draw a crooked mouth that looks like stitches. Allow to set fully before serving or transferring to an airtight container. To store arrange in a single layer then use wax paper or parchment paper before topping with another layer of treats.
Hint: Be sure to use fresh Rice Krispies so the treat doesn't have a stale taste and texture.
Variations
- Swap the Candy Color – Use purple or orange candy melts instead of green to create other Halloween characters like monsters or pumpkins.
- Change the Hair – Try crushed chocolate cookies, chocolate sprinkles, or even shredded coconut tinted black instead of black sprinkles.
- Different Faces – Use red icing for a scar, white icing for teeth, or add candy corn noses for a silly twist.
- Cereal Swap – Use Cocoa Krispies or Fruity Pebbles for a different look and taste while still decorating them like Frankenstein.
Equipment
You don’t need much equipment to make these Frankenstein Rice Krispie Treats. A large pot is essential for melting the butter and marshmallows, and a 9x13 pan works perfectly for pressing the mixture into shape.
Wax or parchment paper helps prevent sticking, especially when layering for storage. You’ll also need a microwave-safe bowl for melting the candy melts and a small piping bag or plastic bag for the icing details. A sharp knife makes it easy to cut the treats into even rectangles for decorating.
Storage
Store Frankenstein Rice Krispie Treats in an airtight container at room temperature for up to three days. If stacking, place a sheet of wax or parchment paper between layers to keep them from sticking together.
You can also wrap the treats in clear cellophane bags for easy sharing.
Top Tips
- Press the rice krispie mixture into the pan gently so the treats stay soft and chewy rather than dense.
- Use fresh marshmallows for the best texture since older marshmallows don’t melt as smoothly.
- Grease your spatula or hands lightly with butter or nonstick spray before pressing the mixture to prevent sticking.
- Melt the candy melts slowly in the microwave in short intervals, stirring often, so they don’t seize or burn. Check out these tips for How to Melt White Chocolate in the Microwave for full instructions.
- Let the rice krispie base set fully before cutting and decorating to keep clean edges.
- Add the eyes and icing while the candy coating is still slightly tacky so the decorations stick well.
