Halloween Rice Krispie Treats are easy to make, fun, and frighteningly delicious! Halloween is coming and I am so excited to share these Halloween Rice Crispy Treats with you all!

I’ve been having so much fun making Halloween treats this year! I started with the Binx Black Cat cookies, then made Halloween Popcorn Balls, Monster Cookies, Spooky Spider Cookies and now these fun Frankenstein and Mummy treats!
The hardest part of making rice crispy treats is waiting for them to cool! But at least you can lick the stirring spoon and the big pot you stirred everything in- but be careful and don't burn yourself!
I love rice crispy treats and how easy it is to shape them into fun treats (Remember my Kaboom Bot Rice Crispy Treats?!). I knew I had to use them to make something for Halloween- and here you have it: Halloween Rice Crispy Treats!
For this recipe I took by amazingly delicious bakery style rice krispy treats and turned them into Halloween Rice Krispie Treats!
How to make rice crispy treats?
You can follow the recipe on the box and they will turn out fine, however, if you want the best rice crispies ever just add a little salt and vanilla, along with a little extra butter. Full instructions in the recipe card below!
How to make Halloween Rice Krispie Treats?
For these treats you will need a batch of rice crispy treats, green and bright white candy melts, candy eyes, and a little black buttercream.
I also use a few piping tips (Wilton #3 Writing Tip and Wilton #104 ruffle tip) for decorating.
How to make rice krispie Frankenstein treats:
- Make your rice crispy treats but add in green food coloring (optional but very fun!)
- Cut into squares and dip in green candy melts for the treats.
- Gently place the eyes onto the dipped treats before the green candy melts set up.
- Using a piping bag with a Wilton #3 writing tip and pipe on the hair and stitches
How to make Mummy rice krispie treats:
- Make your rice crispy treats like you would normally and cut them into squares.
- Melt your bright white candy melts and then place in a piping bag with a tip.
- Put a little bit of candy melt on the back of each eye and press onto the rice crispy treat.
- Then pipe lines using a Wilton #104 ruffle tip over the treat to mimic mummy wrappings.
Save this for later!

Other Halloween Rice Krispie Treat Ideas:
- Dracula: Pipe on some fangs, a widows peak, and add some red food gel as blood
- Spider Web: Similar to my Spider Web Brownies- pipe on a web design coming from the corner of each treat or from the center out
- Monster: Dip the treat in purple candy melts then add lots of candy eyes and Halloween sprinkles
- Pumpkin: Color the rice krispies orange then shape into balls. Add a green jelly bean for the stem and pipe on little Jack-o-Lantern faces
How to melt candy melts:
Place candy melts in a microwave safe bowl with 1 tablespoon refined coconut oil or shortening. Microwave for 30 seconds at 50% power, stir and repeat until melted.
If the candy melts are too stiff and not melting add in more coconut oil 1 tbs at a time, stir, and repeat until you get the consistency you want.
Some times I've added 4 or 6 tablespoons of coconut oil/shortening to get the candy melts liquid enough. There is a point where you've microwaved the melts too much and they burn and become crumbly and are past the point of use, that's why I recommend only microwaving for 30 second intervals at 50% power.
I've noticed different brands and even different microwaves can melt the candies differently.
Black frosting? From scratch vs store bought.
I've used both. They both work well and taste fine.
If you make black frosting from scratch simply make my dark chocolate frosting and add black food gel to it. It will make way more than you need though- so use the leftover for some Halloween Cupcakes or my Halloween Faultline Cake!
Store bought black frosting can be found in the baking aisle or the cake decorating isle and comes in a tube. You will probably need several tubes to decorate these.
You can also use some black food gel (found in the same place as the black frosting) for the stitches but just remember the edible gel doesn't harden making it have the potential for more mess.
Do I have to make rice crispy treats from scratch?
Nope. You can easily use premade store bought rice crispy treats and then just decorate them.
Homemade just tastes WAY better, but store bought is so easy. You're choice!

Halloween Rice Krispie Treats
Ingredients
- 4 Tbs butter
- 7 cups mini marshmallows
- ¼ tsp salt
- ¼ teaspoon vanilla
- 6 cups puffed rice cereal
- neon green food coloring gel optional
- 12 oz bright green candy melts
- 6 oz bright white candy melts
- 2-4 tbs refined coconut oil or shortening
- candy eyes
- black buttercream frosting* see notes on how to make or substitutions
Instructions
- Line a baking sheet with parchment paper- set aside. Butter or spray with non stick cooking spray a 9x13 baking dish- set aside.
- In a medium stock pot over medium low heat melt butter. Add in marshmallows and neon green food coloring (if using for Frankenstein treats). Stir until fully melted.
- Once fully melted, remove from heat and stir in the puffed rice cereal.
- Press the rice krispies into prepared 9x13 baking dish and let cool. Once the rice krispies are cooled and have set up cut them into 24 squares.
Frankenstein Rice Krispie Treats
- Melt the green candy melts in the microwave at 50% power. Heat for 30 seconds, stir and repeat until candy melts have completely melted. If the mixture is too thick (which I find it to be most of the time) add in 1 tbs of coconut oil or shortening, stir thoroughly and test the thickness. If still too thick add more coconut oil, 1 teaspoon at a time until it is your desired thickness. The candy melts should be fairly smooth and liquidy.
- Dip one of the broad sides of the rice crispy squares into the green candy melts and set on the parchment lined baking sheet to harden. Right after dipping the rice crispy treats place the eyes on the them.
- While the candy melts are setting up whip up a half batch up the easy black buttercream (see notes for instructions).
- Using a piping bag filled with black frosting and a Wilton #3 writing tip, pipe on the hair and scars.
Mummy Rice Krispie Treats
- Melt the white candy melts in the microwave at 50% power. Heat for 30 seconds, stir and repeat until candy melts have completely melted. If the mixture is too thick (which I find it to be most of the time) add in ½ tbs of coconut oil or shortening, stir thoroughly and test the thickness. If still too thick add more coconut oil, 1 teaspoon at a time until it is your desired thickness. The candy melts should be fairly smooth and liquidy.
- Add a little of the candy melts to the back of the candy eyes and place two in each rice krispie square.
- Place the white candy melts in a piping bag with a Wilton #104 tip and pipe on lines to look like mummy wrappings.
Notes
- To make black buttercream simply whip up a half batch of my dark chocolate frosting and add several drops of black gel food coloring. You want the buttercream to be a dark grey color. Then let it sett for 10 minutes or so and the color will darken to more of a black. Alternatively, you could buy black frosting from the store and use that.
