Recipe Testing
These rice krispie treats with Oreos are based on my M&M rice krispie treats. I read that Jessie Sheehan had made rice krispie treats with sweetened condensed milk to help keep the treats soft, so that is the only main thing I changed here! You can leave out the sweetened condensed milk if you don't have it on hand though, these treats are still great without them.
Ingredients Needed for Rice Krispie Treats with Oreos
- Marshmallows: you can use regular-sized marshmallows or mini marshmallows. Make sure you're using a fresh bag, if you use an opened bag of marshmallows they might be too stale.
- Oreo Cookies: I'm using regular Oreos but you can use a different Oreo flavor like Golden Oreos, or use a fun and festive Oreo cookie!
- Rice Krispies Cereal: you can use a store-brand of rice cereal or Rice Krispies, I've tested this with both and it doesn't make a difference.
- White Chocolate Chips: I love adding white chocolate chips but you can swap them out for regular chocolate chips or leave them out altogether as I know some people don't like white chocolate!
- Sweetened Condensed Milk: this is a little trick to keep your rice krispie treats super soft! It is optional so feel free to leave it out if you don't have any on hand.

How to Make Rice Krispie Treats with Oreos
Step 1: Place the butter in a large saucepan over medium-low heat. Let the butter melt, and then it should begin to foam and sputter. Stir with a rubber spatula until you see white milk solids at the bottom. Keep cooking (you may need to decrease the heat to low if you use a gas stove) until those dairy solids turn golden brown.
Step 2: Add the sweetened condensed milk (if using), marshmallows, salt and vanilla extract. Stir over low heat until the marshmallows have melted.
Step 3: Turn the heat off and add your rice krispie cereal.
Step 4: Work quickly to stir everything together, making sure the cereal is evenly covered by the marshmallow mixture.
Step 5: Add the white chocolate chips and crushed Oreo cookies and stir until just combined.
Step 6: Pour into an 8x8 baking pan that is lined with parchment paper. Use a greased spatula to even out the top of the treats. You can sprinkle over extra Oreo cookies and white chocolate chips if you wish! Let set for 30-60 minutes, then lift out of the pan and slice.
Expert Tips & Tricks
- Oreo Cookies: to crush the Oreo cookies you can either crush them in a blender or food processor until you have a mixture of large and small chunks. Or you can place the cookies in a ziploc bag and crush them with a rolling pin. I recommend having a combination of finely crushed Oreos and then bigger chunks too!
- Work Quickly: once you add the cereal to the marshmallow mixture you'll have to work quickly before it all sets, so have your prepared pan ready as well as the Oreo cookies and white chocolate chips.
- Stale Marshmallows: you might have an old opened bag of marshmallows in the back of your pantry, but I don't recommend using those! Using stale marshmallows will make your rice krispie treats tough instead of gooey and chewy.
- Big Batch: If you need to make a big batch of these rice krispie treats, double the ingredients and use a 9x13-inch baking pan.
Recipe FAQs
I love browning my butter for rice krispie treats, like I did with these chocolate peanut butter rice krispie treats, but you can also just melt the butter instead of browning it.
If you don't have a can of sweetened condensed milk then feel free to leave it out. I like adding a bit because it makes your treats extra soft but it is optional. I've tested rice krispie treats with and without sweetened condensed milk and both work!
You can melt white chocolate and dark chocolate in the microwave and use a spoon to drizzle the tops of the treats. You can also crush more Oreo cookies on top of the treats just after you've put the mixture in the pan. You could also melt a lot of chocolate on top of the treats (like I did with my chocolate covered rice krispie treats) to create a thick layer of chocolate!
Yes, just follow my rice krispie treats recipe with marshmallow fluff and add Oreo cookie crumbs and white chocolate chips!
