Let’s talk ingredients!
In addition to the tools above, you’re going to need some ingredients to make this recipe, too! Chances are, you might already have some of them in your fridge or pantry. Scroll down to the recipe card for the full measurements and instructions.
Here’s what you’ll need:
- Crispy rice cereal — use your favorite brand! I’ve been known to make these with the whole wheat variety for my kids, but honestly, any variation is good.
- Butter — you can use salted or unsalted butter. If using salted butter, don’t add the salt listed in the recipe card. If using unsalted butter, you need a little extra sprinkle of salt. I have more details about this below so you know how much to add.
- Marshmallows — mini marshmallows melt best and easiest! Make sure they’re fresh because older marshmallows will have lost some of their moisture and not melt as well.
- Halloween Oreos — or your favorite Halloween chocolate sandwich cookie. I prefer the regular kind to the thins OR double stuffed.
- Halloween sprinkles — I prefer jimmies for this recipe, but you could use colored sugar or nonpareils if you have those on hand!
How to make Rice Krispie Treats with Oreos and Sprinkles
Prepare the pan. I like using a 9”x13” baking dish and lining it with wax paper. This will make removing the crispy rice treats easy.
If you don’t have wax paper, simply spray your pan with nonstick cooking spray, and that’ll do the trick, too!
Pro tip!
Measure out the cereal into a large bowl, and set aside. We won’t be mixing these in the bowl, but I’ve found having them measured out before our marshmallow-butter mixture is melty makes your job easier when you’re supposed to be stirring everything together.
Smash the cookies in a plastic bag. Pour these on top of the cereal, and set them aside.
Melt the butter and marshmallows in a large pot over low heat with the salt. Stir until they have melted completely.
Mix the treats. Remove from heat, and pour the cereal and smashed/chopped Oreos into the pot with the marshmallow mixture. Stir quickly until the cereal and cookies are coated.
Make the bars. Pour the mixture into the prepared baking pan. Gently spread it into an even layer with a rubber spatula. If your spatula begins sticking, spritz with the nonstick cooking spray.
DID YOU KNOW?
If you press down hard on the mixture, it will make your treats more compact and less fluffy.
Add an even layer of sprinkles to the top of the treats, and let them cool for about an hour.
Cut into rectangles with a sharp knife, and enjoy!
Erin’s Easy Entertaining Tips
I’m not saying you should host a Halloween party—but if you did, these Oreo Rice Krispie Treats would be a super cute, easy dessert to share with both kids and adults.
Why? They’re tasty, festive and fun!
If you’re planning to make them for a crowd, here are a few ideas on how to do that with less stress:
- Double the recipe. If you’re sharing these with a lot of people, make two batches. Why not just make a double batch? Because you’ll need a giant pot for that.
- Wrap them up individually. If you’re sending guests home with these, get some cute take-home bags* (affiliate link) and box these treats up to send home with your friends.
- Serve them on a platter. One of my favorite ways to serve treats is on a big platter* (affiliate link). Let guests grab them when they want a treat. Be sure to have some festive napkins alongside the platter so they can have a place to set their treats!
Frequently Asked Questions
Sure! Since Oreos make so many seasonal varieties, feel free to take this idea and transform it into whatever holiday is happening soon! Swap out the cookies and the sprinkle colors, and have fun.
Marshmallows are an integral part of krispie treats, so I do not recommend finding a substitute for them.
The treats harden as they cool, so it’ll take at least 30 minutes after they’ve been in the pan.
No. Please don’t. As marshmallows sit in the pantry, they lose moisture and their texture changes. They will have a harder time melting, and when they do, they will become more of a gelatinous blob. They run the risk of overcooking and making tougher krispie treats because you’ll need to cook them for longer.
Quick Tips and Tricks for the best crispy rice treats
- Swap out the Oreos and sprinkles for a different holiday. Yes, these were made for Halloween, but Oreos offer all kinds of seasonal cookies. Use those and your favorite sprinkles to make any type of seasonal treat.
- Use fresh marshmallows. They melt more easily and will provide a better texture for your treats. (How do I know this? I’ve attempted this recipe with older marshmallows, and they didn’t turn out quite right.)
- Make them gluten free by using GF Oreos (or other chocolate sandwich cookies) and GF crispy rice cereal. Be sure to read the labels.
- Store in an airtight container at room temperature for 2-3 days. After this point, the treats will begin to harden.
