How to make Frankenstein Rice Krispies
STEP 1: MELT THE MARSHMALLOWS
Add the marshmallows and butter to a large bowl and microwave to melt. Make sure to thoroughly mix the butter into the melted marshmallows. Use a rubber spatula to scrape along the sides and bottom of the bowl to get it all. See directions for melting the marshmallows and butter on the stovetop in the recipe card below.
Tip: cut the butter into four pieces so that it will melt faster and require less melting time.

Then, add the vanilla extract, salt and green food coloring and stir until the mixture turns green. Start with one teaspoon of food coloring and add more as you'd like.
STEP 2: ADD THE RICE KRISPIES CEREAL
Add the rice krispie cereal to the bowl and gently mix it in so that all the cereal is coated in green melted marshmallows. Then, transfer the rice krispies into a baking dish sprayed with non-stick cooking spray.


Very gently press the rice krispies into the baking dish. You can use your rubber spatula to do this, but I find the easiest way to do it is to lightly wet your hands and then use them to gently press the rice krispies into the pan. You only want them to be slightly wet, but the small amount of water will help prevent the rice krispies from sticking to your hands.
STEP 3: DECORATE!
After letting the rice krispies firm up for an hour or two, cut them into equal squares.
To decorate, start by melting the almond bark and dipping the top of each rice krispie treat in the melted chocolate. Let them harden on a piece of wax paper as you draw on the rest of his face.

Tip: Use a small bowl for the melted chocolate to create depth, which will make it easier when dipping in the rice krispie treats!
I like to place the candy eyes on first, securing them to the rice krispie treat with a dot of icing on the back of each eye. Then, use the icing to draw on the scar and smile, and finally to attach the marshmallow bolt!

Substitutions & Variations for Frankenstein Decorations
- Substitute black candy melts for the chopped almond bark. Both are designed to melt easily and be used for similar purposes. You could also use a chopped dark chocolate bar or chocolate chips.
- I like the convenience of a store-bought mini tube of icing, but you can also a black gel or add melted chocolate or black frosting to a piping bag fitted with a small round tip to pipe on Frankenstein's face.
- Use Rolos, mini Reese's cups, pretzels, or candy corn for Frankenstein's neck bolt!


Frankenstein Rice Kripsie Treats
Ingredients
- 12 ounce package of mini marshmallows + 18 mini marshmallows divided
- 4 tablespoons unsalted butter cut into 4 pieces
- 1 teaspoon green food coloring
- 1 teaspoon vanilla extract
- 1 ⁄4 teaspoon salt
- 5 cups rice krispies cereal
- 1 cup chopped chocolate almond bark
- 9 pairs of candy eyes
- Black icing
Instructions
- Lightly coat a 9 x 9 baking pan with non-stick cooking spray. Set it aside for now.
- Add a 12-ounce package of mini marshmallows to a large microwave-safe bowl and top with the squares of butter. Microwave for 1 ½ minutes. Then, stir with a rubber spatula until it's a smooth buttery marshmallow mixture. Make sure to fully incorporate the melted butter into the marshmallows.
- Then, add the vanilla extract, salt and green food coloring to the melted marshmallows. Start with 1 teaspoon of green color and add more as desired. Stir again until the gooey marshmallow mixture is a uniform shade of green. Make sure to scrape the bottom and sides of the bowl!
- Stir in the rice krispies cereal making sure that all the cereal is fully coated with the green marshmallow mixture. Then, use your spatula to scoop the rice krispies into the prepared pan.
- Lightly wet your hands and gently press the rice krispies into the pan, making the top layer even as possible. Don't press too hard because you want the rice krispies treats to stay soft and gooey! Let the Frankenstein rice krispies treats sit in the pan for about one to two hours to cool and firm up.
- When you're ready to decorate, slice the rice kripsies into equal squares.
- Add the chopped almond bark to a small bowl and melt for one minute in the microwave. Stir, microwave for another 30 seconds, and then finally stir until it's smooth.
- Lay down a piece of parchment paper or wax paper to set the rice kripsies on after dipping them in the chocolate. To make Frankenstein's hair: dip the top ½-3/4 inch of each rice krispie into the melted chocolate, letting the excess chocolate fully drip off before setting it down. Let the chocolate harden.
- Dab the back of each candy eye with a small dot of icing to secure them to Frankenstein's face. Use the icing to draw on a smile below them, and a scar going diagonally across his forehead. Then, use the icing to glue two mini marshmallows, one on the bottom of each side of the treat, to create the bolt in his neck.
Notes
- Microwaves vary in power. You may need a little more or less time to melt the chocolate.
- To melt the marshmallows on the stove: Add the marshmallows and butter to a large pot over medium-low heat, stirring occasionally. Once the mixture is melted and smooth, remove it from heat. Stir in the vanilla extract, salt, and food coloring to the melted marshmallows in the pot. Then add the rice recipes to the pot, stirring to coat them. Scoop the rice kripsies into the baking dish and proceed with the original recipe instructions.
STORAGE
Keep these Frankenstein treats stored in an airtight container on the counter at room temperature to keep them soft and gooey. They should keep for about two days, maybe one or two more if properly stored. I like to use a baking dish that comes with a fitted lid, like this one, or use plastic wrap to securely cover it - just make sure it isn't smooshing Frankenstein's face!SUBSTITUTIONS
