Make Monster Rice Krispie Treats for Halloween!
These Monster Rice Krispie Treats crack me up every year. They’re just regular Rice Krispies dipped in chocolate with candy eyes, but somehow, once we stick those goofy eyes on, they turn into the stars of the Halloween spread.
I usually make these Monster Rice Krispie Treats with the kids right before trick-or-treating. It’s messy fun, takes about ten minutes, and everyone ends up sneaking at least one before the chocolate sets. They’re fun, low-effort, and just the right kind of silly for Halloween.
Happy Cooking!

Monster Rice Krispie Treats Ingredients
- Rice Krispies cereal: Other puffed cereals like Cocoa Krispies or Fruity Pebbles work, too. You can use puffed rice cereal, but the treats will be chewier and not as crispy.
- Marshmallows: Any large marshmallows will do. If you’re feeling adventurous, try flavored marshmallows! Mini marshmallows also work, but they might melt quicker, so keep an eye on the pot. One large marshmallow equals about 10–12 mini marshmallows.
- Butter: I recommend unsalted butter so you can better control the amount of salt in the recipe, but salted works, too.
- Chocolate candy melts: They’re easier than regular chocolate, especially if you’re baking with kids. But you can also melt the same amount of chocolate with a tablespoon of coconut oil.
- Candy eyeballs: They’re usually easy to find at the store around Halloween. Or, you can make homemade eyes with white chocolate and a dot of dark chocolate.

Monster Rice Krispie Treat Recipe
Monster Rice Krispies treats are fun to make with puffed rice cereal and marshmallows to form the Rice Krispies treat that is then dipped in chocolate and decorated with candy eyes.
Ingredients
- 6 tablespoons unsalted butter
- 40 large marshmallows Jet-Puffed work best
- 6 cups Rice Krispies cereal
- 16 ounces chocolate candy melts
- 32 large and small candy eyeballs
Instructions
- Line a 9-x-13–inch baking pan with parchment paper. Leave excess on at least two sides so you can easily remove the treats after they set.
- Add the butter to a large pot and set it over medium heat. Once it melts, the butter will begin to foam. Keep a close eye on it and cook for about 5 minutes more, or until you see brown specks on the bottom of the pot and the mixture smells nutty.
- Reduce the heat to low and add the marshmallows. Cook, stirring constantly, until the marshmallows melt.
- Remove the pot from the heat and stir in the cereal, working quickly to make sure everything is well-combined.
- Scrape the mixture into the prepared pan. Using a nonstick spatula, press the mixture into an even layer. Let it sit for at least 30 minutes.
- Once set, remove the treats from the pan using the parchment paper as a sling. Cut into 16 equal bars with a sharp knife.
- Melt the chocolate melts per the package instructions. Place a stick in the middle of each treat, then dip it in the melted chocolate. Shake off any excess chocolate. Press the candy eyes into the treats and let them sit for 10 minutes.
Equipment
- Decorative Sticks
Notes
- My Top Tip: Keep an eye on the marshmallows while they melt. Stir constantly so they melt evenly, don’t get too gooey, and don’t stick to the bottom of the pot.
- Storage: Store the Monster Rice Krispies in an airtight container. If you stack them, put a piece of parchment paper between each layer so they don’t stick to each other. The treats will stay fresh at room temperature for up to 5 days, or in the fridge for up to 1 week.
- Freezing: Wrap the individual Monster Rice Krispies in plastic wrap, then place them in a zip-top freezer bag. They’ll last in the freezer for up to 3 months. Thaw at room temperature and enjoy.

Recipe Variations
- Add vanilla extract. After the marshmallows melt, stir in ½ teaspoon vanilla extract for a hint of sweetness.
- Make colorful monsters. Add dye-free food coloring to white candy melts and make orange, purple, or green Rice Krispie monsters.
- Get creative with edible decorations. Try licorice strings for hair or candy corn for monster teeth!
Recipe Tips
- Keep an eye on the marshmallows while they melt. Stir constantly so they melt evenly, don’t get too gooey, and don’t stick to the bottom of the pot.
- Stir the cereal into the melted marshmallows quickly. You want to evenly coat the cereal. This makes it easier to spread out in the pan before the mixture sets.
- Press the mixture into the pan gently, not firmly. If you press it too much, the treats might get hard and dense. Press only until it holds its shape.
- Use a cup with tall sides for the candy melts. This makes it easier to dip the treats halfway into the chocolate.
- Cool the treats in the fridge. If you’re short on time or eager to dig in, put the pan in the fridge for about 10 minutes to set the treats quicker.
