The gooey, sticky texture and rich, sweet flavor of these Halloween Rice Krispie Treats will make them a standout addition at your spooky celebration.
These Monster Rice Krispie Treats are Perfect for Your Next Halloween Party!
When it comes to creating the Halloween food I’ve come to be known for, my goal is always to make things that TASTE as good as they look.
This seems obvious, but it’s not always the case with themed food recipes you’ll find online. A lot of them are designed to LOOK really cute (or creepy), but the flavor was clearly an afterthought.
What sets this Halloween Rice Krispie Treats recipe apart is my attention to FLAVOR detail, down to a few grains of salt. Yes, a pinch of salt balances the sweetness of the marshmallows and creates a more nuanced flavor.
The taste and texture of these adorable treats will make them a standout addition to your spooky celebration.

Halloween Rice Krispie Treats Ingredients

- unsalted butter – used to help melt the marshmallows.
- mini marshmallows – these provide the signature stickiness for these Frankenstein rice krispies treats.
- Rice Krispies cereal – the classic choice for that crispy texture. Use generic “crispy rice cereal” at your own risk. I go name brand all the way here!
- kosher salt – not traditional in all RTK recipes, but I like to add a pinch of salt to mine to balance the sweetness in a really nice way.
- green food coloring – for the Frankenstein look for these Rice Krispie Halloween treats! You can use liquid or gel coloring. More info on this under “Home Chef Tips.”
- chocolate chips – we’ll be melting these to create the sticky base for Frankenstein’s “hair.”
- chocolate sprinkles – sprinkling these over the chocolate complete the hair look. You can also melt candy melts for this, but I think the flavor of chocolate chips is much better.
- candy eyeballs – these bring your monsters to life!
- mini peanut butter cups – for the neck bolts on the monster. Look for a bag of Reese’s Minis Unwrapped.
- black writing gel – for making the monster mouths and drawing on some stitches.
- red writing gel – an optional additional to add some “blood” as decoration. Writing gels should be available in the baking aisle of your local grocery store.
How to Make Frankenstein Rice Krispie Treats
1. MELT. In a large pot, melt the butter, then add the marshmallows, salt and enough food coloring to make everything bright green. Stir until smooth, then assess the color and add more food coloring if needed.
2. CEREAL. Remove the marshmallow mixture from the heat, then add the Rice Krispies and stir until the cereal is fully coated in the marshmallow mixture.
3. PRESS. Press the mixture into a baking pan greased with cooking spray, using a piece of parchment paper to flatten the mixture into the pan. Let stand at room temperature for 15 minutes to cool.
4. CUT. Turn the treats out onto a cutting board and cut rectangle in half lengthwise. Then, cut each half into 5 pieces crosswise.
5. DIP. Melt the chocolate chips in the microwave until smooth. Dip one end of each treat in the melted chocolate and place on parchment paper.
6. SPRINKLE. Immediately after dunking in chocolate, cover the chocolate with sprinkles.
7. FINISH. Use the remaining melted chocolate to attach the candy eyes and mini peanut butter cups as neck bolts for the Frankenstein rice krispie treats. Use black writing gel to add mouths and stitches, and red writing gel to add a bit of “blood,” if desired.
Halloween Rice Krispie Treats Recipe Home Chef Tips
- Make sure your marshmallows are fresh! A brand new bag, if possible. This is key to a perfect texture in the final treats.
- I do not provide an exact measurements for the green food coloring because there are so many different varieties of food coloring available these days (classic liquid food coloring, squeeze gel, gel in little tubs, oil-based dyes, etc.). Add as much as you need to make a vibrant green color.
- Press the cereal mixture firmly into the pan, but don’t press it TOO hard. Packing it too tightly can make your fun Halloween treats really dense and hard.

Rice Krispie Halloween Treats FAQs
Yes, definitely! Rice Krispie treats are one of the best make-ahead desserts because they hold their shape and texture so well. Just make sure you store them in a really airtight container, and keep them at room temperature.
While you technically can use stale marshmallows, it’s really not recommended. Stale marshies don’t melt as smoothly as fresh ones, so you might end up with a lumpy texture and hard treats. For best results, use a fresh bag of marshmallows.
To prevent sticking, lightly spray your spatula or spoon (or hands!) with nonstick spray before pressing the mixture into the pan. Or, my favorite trick is to use a piece of parchment or wax paper to press the mixture down. My hands stay clean!
