My Halloween Rice Krispie treats recipe is the perfect candy-filled snack to make this weekend! Soft, chewy, and packed with candy corn and Halloween sprinkles, this no-bake dessert is an easy way to end off spooky season and use up all that candy.
Candy Corn Rice Krispie Treats
Making these candy corn Rice Krispie treats after Halloween has become a tradition at my house. We always have unused bags of candy corn amongst the other bags full of candy from trick-or-treating. So I just add them into my classic Rice Krispie treats and it makes them even better!
It only takes about 15 minutes to throw everything together, then let them set up and they’re ready for snacking. We love eating these for move nights. You can make a chocolate Rice Krispies version too for even more fun!

Wait to Add the Candy — Here’s Why
For the best texture and look, let the Rice Krispie mixture cool for 5–10 minutes before adding candy corn or sprinkles. If you stir them in too soon, the candies can melt and bleed color into the marshmallows. Waiting a few minutes keeps the treats bright and picture-perfect while still allowing the candy to stick.

Notes
- Don’t heat up the marshmallow mixture too much. If it’s too hot, your end result will be hard, instead of soft/chewy treats.
- Always stir the cereal off the heat to prevent sticky clumps.
- Don’t press the mixture too firmly, or your treats will turn out hard.
- Use parchment paper on top when pressing to avoid sticking.
- For the best color, let the treats cool for 5-10 minutes before adding candy corn or sprinkles so they don’t melt.
- For extra Halloween flair, drizzle melted white chocolate and top with more candy corn before serving.
- I’d avoid putting these treats in the fridge. They’ll get pretty hard and lose their desired consistency.
- Add a slice of bread or a few marshmallows to the storage container to keep your treats soft longer.

How to Make Rice Krispie Treats with Candy Corn Step-by-Step
Prep: Gather the short list of ingredients for this Halloween Rice Krispie Treats recipe. Line an 8×8-inch baking pan with parchment paper and set it aside.
Melt the Marshmallows: In a large pot set over low heat, melt 2 tablespoons of salted butter. Then add in 2½ cups of mini marshmallows and allow them to melt completely, stirring constantly so they don’t burn. It’s important to cook just until the marshmallows melt, then remove from heat. If they cook too long, the treats will be too hard.
Add the Cereal: Next, remove the pot from the heat, stir in 1 teaspoon of vanilla extract and 4 cups of Rice Krispies cereal.
Top and Set: Transfer the cereal and marshmallow mixture to the prepared pan, and spread it into an even layer. Wait 5-10 minutes for the treats to cool slightly to avoid melting the candies. Then top with 1 cup of candy corn and Halloween-themed colored sprinkles (if desired). Place another sheet of parchment paper on top and press down firmly to pack the rice krispies–be careful, they will be hot! Do not pack them too firmly or they will turn out hard. Set the rice krispies aside at room temperature to cool completely, about 1 hour.
Slice and Serve: Once cooled and set, slice the Rice Krispie treats into squares or bars, and enjoy!
How to Store
Store leftover Halloween rice krispie treats in an airtight container at room temperature for up to 5 days. You can add a slice of bread or a few whole marshmallows to the container to help keep them softer for longer. Do not store these treats in the refrigerator or freezer, as both will cause them to turn hard and brittle.
