These Frankenstein Rice Krispie Treats are one of the cutest Rice Krispies Treats for Halloween, and bonus, they are so simple to make!
I am so excited for Halloween this year! If you ask my boys what their favorite part of Halloween is they would say dressing up and going to get candy. While I do love seeing them all decked out in their Star Wars or TMNT outfits I’d have to say my favorite part of Halloween (and every holiday really) is all the fun treats I get to make.
These rice krispie treats for Halloween may just be my favorite of all the Halloween desserts I’ve made! I mean come on; how can you go wrong with Frankenstein rice krispie treats, am I right?! If you want some more information here are a few other Halloween treats we love!

Frankenstein Rice Krispie Treats
These Frankenstein treats are just a little bit spooky and a whole lot of fun! They are super easy to make and a great treat for playgroups, class parties or just because.
The nice thing about these little guys is you don’t have to have a steady hand or dip the treats perfectly into the chocolate to have them turn out cute. A little extra chocolate here or frosting there adds that much more character to these monstrous treats!
It’s also a great recipe to let the kids help make. I’ve made these 3 times now and I let my boys help me with everything except melting the marshmallows and butter (they are still a little young to be using the stove).
How to Make Frankenstein Rice Krispie Treats
Tips for Making Rice Krispie Frankensteins:
- I used the recipe for the rice krispie treats on the back of the cereal box. The only difference was I melted the butter and marshmallows together at the same time. I’ve found through lots of trial and error that this makes the finished treats more moist and ooey-gooey.
- Start with a very small amount of green food coloring and add more as you need. A little gel food coloring goes a long way.
- When using the silver spray mist be prepared to get messy; my hands looked like I was auditioning for the part of the Tin Man in Wizard of Oz after I was done.
- When finished decorating let set up in the fridge for an extra hour or so. This will help keep the eyes and screws (marshmallows) attached.
- Melt butter and marshmallows together.
- Add green food coloring.
- Add rice krispies and stir to combine, press mixture into a 9×13 pan.
- Cut rice krispie treats into small rectangles and dip tops in the black melting candy to make your hair.

Instructions
- Melt butter and marshmallows together in a saucepan over medium heat stirring constantly.

- Pour cereal/marshmallow mix into a greased 9x13 dish and spread out evenly.
- Let set in fridge for 30 minutes.
- Remove from fridge and cut into rectangles. Place on wax paper.
- In a microwave safe bowl melt half a bag of the melting chocolates in 30 second increments stirring in between. Continue to cook and stir until chocolate is smooth.
- Dip one of the smaller ends of the treat into chocolate about 1" down.
- Return to wax paper and let harden (2-3 minutes).
- Repeat with remaining treats.
- Using the black frosting as glue attach candy eyes just below chocolate "hair".
- Use the black frosting to draw mouth under eyes.
- Spray marshmallows (2 per treat) with silver color mist. Let dry for 3-5 minutes.
- Using the black frosting again as glue attach silver marshmallows to both sides of the treat.

Made these for Halloween they were a lil tuff to do but had lots of fun in the process we used melted marshmallow cream to make eyes and ears stick 😊
