How to Make Halloween Oreo Rice Krispie Treats

First add the following ingredients:

  • Butter – I use salted butter for this recipe. It adds a richness to this recipe and helps loosen up the marshmallows and make them adhere to the rice krispies. 
  • Jumbo Marshmallows – I love using jumbo marshmallows. Marshmallows are just a mixture of sugar, water, and gelatin thats whipped up into a soft but solid consistency. We will be melting the sugar in them to make that yummy glue to hold the krispies together. 
  • Halloween Style Oreos – you can use regular oreos for this but the orange center Halloween ones make for a special spooky treat. I love the color and texture that they add. Be sure to cut them into at least quarters before adding them. 
  • Rice Krispies – krispies have a snap, crackle, and pop that makes them the perfect chewy base for these easy dessert treats. You don’t need to use the main brand Kellogg cereal, feel free to use off brand krispies.

Once you have assembled your ingredients, make the Halloween Oreo Rice Krispies using the following method:

Step 1 – Melt the butter and marshmallows in a pan on the stovetop on medium heat. Make sure you stir it consistently to keep it from burning on the bottom. I recommend using a silicone spatula to stir it. Add the crushed oreos and stir to combine. 

Step 2 – Pour the rice krispies into a large bowl and pour the sticky mixture over. I like to add half the cereal then pour and add the rest so it’s easier to mix. Mix it well so everything is sticking together. 

Step 3 – Spray a casserole dish thoroughly and pour the mixture into it. Put the whole Oreos on the top of the mixture. Put some water on your hands and push the rice krispies to compact them. 

Step 4- Leave the rice krispies out at room temperature for at least 35 minutes or until set. 

Step 5 – Cut into as many pieces as you want and enjoy!  

Tips and Trips for Halloween Oreo Rice Krispies

Tip 1 – Use a non-stick pan. I use a nonstick pan when making the butter/marshmallow mixture on the stovetop. It makes it easier to clean later.

Tip 2- Add other treats. If you want to make these extra special, you can crush up other candies and add them to the sticky marshmallow mixture before you combine it with the krispies.


Can I use a different type of cereal?

Yes! These can be made with any type of cereal you want. Cereal is dry by nature which lends itself well to the gooey sugary butter and marshmallow mix. Substitute any other cereal cup for cup

How well do they keep?

If you wrap the rice krispies individually in plastic wrap they will keep at room temperature for 3-4 days. They will be softer each day you leave them.
