So easy to make right in your microwave and decorated with halloween colored candies and chocolate, they will disappear right before your eyes! These are also great to make and send to school with your children for their holiday celebration with their classmates.
To make this recipe you will need: Microwave, Marshmallows, Butter, Green Food Coloring, gumdrops, halloween colored jelly beans, and pretzels.
The first time I made these rice krispie treats was for a Grown-up Halloween Party that I hosted with my former daughter in law. She is a huge fan of Halloween and what more fun can you have with your family than to throw a fun Halloween party!
If you follow me on Instagram and Facebook, then it is likely you have seen that we are in the midst of kitchen renovation! I finally have a sink, oven and microwave, but still don’t have a working cooktop yet. So, since I wanted to make these little treats, I needed to use the microwave.
Use the microwave to make these Frankenstein Rice Krispie Treats super quick and easy to make!
I don’t make rice krispie treats too often anymore. Mainly because we are trying to eat healthier. I pretty much leave the sugar alone, but I know when I make them going forward I will always use the microwave. It is less mess and so quick!
When do you add the food coloring?
Always add the food coloring to your marshmallow mixture after microwaving the first two minutes. You may not need to microwave any additional time if your marshmallow and butter melted completely enough to combine (mine only took 2 minutes). Once you stir the food coloring in, it should look like the photo above.
I like to use an 8×8 glass pan for rice krispie treats. I like to make them thicker and an 8×8 pan will do just that! Once you have added the rice krispies to the marshmallow mixtures, you will transfer them to a well buttered pan and pat them down with a spoon that you have coated with butter Be sure to press down to pack the treats into the pan. Once they have been packed and scored, go ahead and refrigerate them so they will firm up before decorating.
Candy I used when making Frankenstein Rice Krispie Treats.
- small spice gumdrops
- Monster Mash Jelly Belly Jelly Beans (black color for eyes). I cut the end of each jelly bean off to make a small black eye.
- dark melting chocolate (for the hair and drawing the mouth)
If you don’t have these candies, that is fine, you can improvise! Back when I first made these for our adult halloween party, I painted the face on and didn’t use candy. For the ears I used pretzels and mini marshmallows.

PIN IT! Frankenstein Rice Krispie Treats! (Microwave Method)
Frankenstein Rice Krispie Treats made in the microwave with the traditional rice krispie treat recipe! Halloween is a whole lot of fun with Franken Treats!
- 40 Large Marshmallows
- 3 tablespoons salted butter
- 6 cups rice krispie treats
- green food gel coloring
- assorted Halloween candy for decorating
Butter an 8x8 pan. Set aside.
Place marshmallows and butter in large microwave safe bowl.
Measure out six cups rice krispies and place in bowl, set aside.
Microwave marshmallows and butter for 2 minutes. Remove from microwave and stir. Add food coloring. I did not measure the food coloring, I added it and adjusted to bring it to the green I wanted. I may add more food coloring if I were to make this again to make the treats greener.
If your marshmallow mixture needs to be microwaved longer, place back in microwave and cook for another 60 seconds.
Remove from microwave and stir in rice krispies until coated with marshmallows.
Turn rice krispies mixture out into prepared 8x8 pan and press down to pack into pan with a spoon. Coat the back of the spoon with butter to prevent sticking.
Score the rice krispie treats (12 pieces) and refrigerate until firm.
Remove treats from refrigerator and decorate with chocolate and candies as desired.
