Gooey Oreo Rice Krispie Treats (5 Ingredients!)
These Gooey Oreo Rice Krispie Treats are soft, chewy, extra marshmallowy, and loaded with Oreo cookie chunks in every bite. They only require five ingredients, come together quickly, and do not require turning on the oven.
Rice Krispie treats are already one of the easiest desserts you can make, but adding Oreos takes them to another level. You get the classic buttery marshmallow flavor, crispy cereal, gooey pockets of marshmallow, and plenty of cookies-and-cream flavor throughout.
And listen, I do not want a dry Rice Krispie treat. If I have to fight through it with my teeth, I do not want it. These stay soft and gooey because we use plenty of marshmallows, melt them gently, and avoid pressing the mixture too firmly into the pan.

Ingredients You’ll Need
You only need a handful of ingredients to make these Oreo Rice Krispies Treats. As always, the full measurements are written down below in the recipe card.
- Salted Butter: Butter adds flavor and keeps the treats soft. I prefer salted butter because it helps balance the sweetness from the marshmallows and Oreos. You can use unsalted butter, but add a pinch of salt to the melted marshmallow mixture.
- Mini Marshmallows: Mini marshmallows melt quickly and evenly. Part of the marshmallows are melted with the butter, while the rest are folded in at the end to create gooey pockets throughout the treats. Make sure your marshmallows are fresh. Older marshmallows can be harder to melt and may make your Rice Krispies treats firmer.
- Vanilla: A little vanilla adds warmth and enhances the cookies-and-cream flavor. Vanilla extract or vanilla bean paste will both work.
- Rice Krispies Cereal: Classic Rice Krispies cereal gives these treats their light, crispy texture. Measure the cereal carefully, as adding too much can make the finished bars dry out.
- Oreo Cookies: Roughly chopped Oreos add chocolate cookie pieces and creamy filling throughout the treats. Keep the pieces slightly chunky instead of crushing them into fine crumbs. Larger pieces give you more Oreo flavor and a better texture in every bite.
How to Make Gooey Oreo Rice Krispie Treats
1. Prepare the Pan
Line a 9 x 13-inch baking pan with parchment paper, leaving enough overhang to easily lift the treats out later.
2. Melt the Butter and Marshmallows
Melt the butter in a large pot over low heat. Once melted, add the first portion of mini marshmallows. Stir constantly until the marshmallows are almost completely melted. Remove the pot from the heat while a few small pieces remain.
3. Add the Cereal and Oreos
Stir in the vanilla, then gently fold in the Rice Krispies cereal. Once the cereal is mostly coated, add the chopped Oreos and reserved mini marshmallows. Fold everything together just until evenly combined.
Try not to overmix. You want to keep some visible marshmallow pockets and larger Oreo pieces throughout the bars.
4. Gently Press Into the Pan
Transfer the mixture to the prepared pan and spread it into an even layer. This is where many Rice Krispie treats go wrong. Do not firmly pack the mixture into the pan. Use lightly buttered hands or a greased spatula to gently press everything into place. The harder you press, the denser and firmer the treats will be.
Top with the remaining chopped Oreos and lightly press them onto the surface. Let cool and slice.
Tips for the Best Oreo Rice Krispie Treats
- Use Low Heat: High heat can overcook the marshmallows, making the treats firm. Keep the stove on low and stir frequently.
- Fold Gently: Overmixing can crush the cereal and break the Oreos into tiny pieces. Fold just until everything is coated.
- Do Not Pack the Pan: Lightly press the mixture into the pan. You are shaping it, not trying to compress it into a brick.
- Use a Large Pot: The mixture takes up more room than you may expect. A large pot or Dutch oven makes it much easier to fold the cereal and Oreos without spilling everything onto the counter. I have been there, and sticky marshmallow cereal all over the stove is not the experience we are going for.
Can I Use Double Stuf Oreos?
Yes, you can use Double Stuf Oreos in this recipe.
They will add more of the creamy filling flavor and may make the treats slightly sweeter. Regular Oreos offer a slightly more chocolatey cookie flavor, but both options work well.
You can also use another Oreo flavor, such as Golden Oreos, birthday cake Oreos, or mint Oreos.
How to Store Oreo Rice Krispie Treats
Store your Oreo Rice Krispie Treats in an airtight container at room temperature for up to four days. For the best texture, enjoy them within the first two days while the cereal is still crisp, and the marshmallow mixture is at its softest.
If you are stacking the treats, place parchment or wax paper between each layer to prevent them from sticking together. Avoid refrigerating them, as cold temperatures can firm up the marshmallows and make the bars harder.
If a treat becomes slightly firm, microwave it for about five seconds to bring back some of that soft, gooey texture.
Frequently Asked Questions
The marshmallows were likely cooked at too high a temperature or heated for too long. Pressing the mixture firmly into the pan can also create dense, hard treats.
The cereal may not have been fully coated, or the treats may not have had enough time to set before slicing. Let them cool for at least 30 to 45 minutes.
Yes. Use a 9-inch square pan for extra-thick treats. They may need a little longer to cool before slicing.
Traditional Oreos and Rice Krispies cereal are not always considered gluten-free. Use certified gluten-free crispy rice cereal and gluten-free Oreos if needed, and check every ingredient label carefully.
Absolutely. Adjust the recipe based on your desired or what you have on hand. Biscoff cookies would be amazing!

- 1 teaspoon vanilla bean paste or pure vanilla extract
- ¼ teaspoon kosher salt
- 6½ cups Rice Krispies cereal
- 24 Oreo cookies roughly chopped
Instructions
- Line a 9×13-inch baking pan with parchment paper, leaving a slight overhang on two sides for easy removal.
- In a large Dutch oven or heavy-bottomed pot, melt the butter over low heat.
- Add the entire bag of mini marshmallows and stir continuously until they are about 95% melted. Remove the pot from the heat while a few small marshmallow pieces remain, they will continue melting from the residual heat.
- Stir in the vanilla and salt.
- Add the Rice Krispies cereal and fold gently until evenly coated.
- Then add about 3/4 of the chopped Oreos and the reserved 2 cups mini marshmallows. Mix just until combined. Avoid overmixing so the Oreos stay chunky and the marshmallows remain intact.
- Transfer the mixture to the prepared pan.
- Using lightly buttered hands or a buttered spatula, gently press the mixture into an even layer. Do not firmly pack the treats, or they'll become dense instead of soft and gooey.
- Sprinkle the remaining chopped Oreos over the top and gently press them into the surface.
- Allow the treats to cool at room temperature for about 45 minutes before slicing into squares. Enjoy!
