Gather This
You only need a few simple ingredients to make this fun monster rice krispie treats dessert. A full list of ingredients with measurements for this recipe is available in the printable recipe card below.
- Salted butter – While we usually use unsalted butter for baking recipes, since there is no other salty addition, you can use salted butter for this recipe.
- Large marshmallows (or mini marshmallows) – Either size will work, but it may be helpful to tear larger marshmallows into smaller pieces so that they melt more quickly.
- Rice Krispies cereal – You can use the brand name or a generic store version.
- Candy melts – Use equal parts of magenta, lime, and orange candy melts. Or, choose your own favorite colors.
- Candy eyeballs – You can find fun candy googly eyes at a grocery store or craft store — or look for them online. Get them all in one size, or get a variety and alternate between small and large candy eyes when decorating.
- Black frosting (with pen tip) – Use this to decorate your treats after frosting. Or, you can also melt black candy melts and drizzle or pipe it over the treats.
Perfect Pairings
These fun Halloween monster rice krispie treats are fantastic snacks all on their own, or you can serve them with a big glass of cold milk or hot chocolate. You can also serve them with ice cream or chocolate pudding or drizzle them with melted chocolate, white chocolate, chocolate sauce, or salted caramel.
If you’re trying to keep things fun and festive, you can serve them with things like Mummy Oreo Cookies, Ghost Cookies or even Monster Bark.
Variations
There are lots of ways to jazz up these cereal treats. These are just a few ideas.
- Fluff – 7 ounces (1 ½ cups) of marshmallow fluff can be swapped for the marshmallows
- Cutters – Use cookie cutters to make fun shapes.
- Nuts – Fold in crushed nuts for some added texture and flavor.
- Dried fruit – Stir small pieces of dried fruit into the Rice Krispies for a pop of color and sweetness.
- Coloring – For a fun twist, try adding food coloring to the marshmallow mixture before adding the Rice Krispies. Try using green for some fun Frankenstein Rice Krispie treats.
- Nut butters – Add creaminess and nutty flavor by stirring in peanut butter or almond butter.
- Chocolate chips – Mix mini chocolate chips in with the Rice Krispies.
Common Questions About Monster Rice Krispie Treats
If you heat the marshmallow and butter mixture too quickly or at too high of a temperature, the treats can become hard. Instead, cook the mixture at a lower temperature and give the mixture time to melt and become smooth.
Rice Krispie treats can be stored in the refrigerator, but they can be stored on the counter in an airtight container, too.
When making sweets, it’s important to be precise when you measure. Using too much butter can result in Rice Krispie treats that may not stay together and have a wet texture
No—you can use store-bought squares or homemade; both coat and set the same.
