What Ingredients You Will Need
This recipe uses simple, pantry-friendly ingredients to deliver bold flavor and satisfying texture. Here’s what you’ll need:
- Marshmallows: One 10-ounce bag of mini marshmallows for maximum gooeyness.
- Unsalted Butter: 4 tablespoons, melted (adds richness).
- Crispy Rice Cereal: 4 cups for that classic crunch.
- Oreos: 15-20 cookies, crushed into chunks (don’t pulverize them—you want some texture).
- Vanilla Extract: 1 teaspoon to enhance the flavors.
If you’re missing an ingredient, don’t worry! You can swap out Oreos for your favorite cookies or use flavored marshmallows for a fun twist.
Equipment Needed

- Large Saucepan: For melting the butter and marshmallows.
- Mixing Spoon: A sturdy spoon for combining the ingredients.
- 9×13-inch Pan: For spreading and setting the treats.
- Parchment Paper: To prevent sticking.
- Rolling Pin or Ziplock Bag: For crushing the Oreos.
If you don’t have a 9×13-inch pan, you can use any similarly sized dish or even a baking sheet—just adjust the thickness accordingly.
Preparation Method
- Start by preparing your pan. Line a 9×13-inch pan with parchment paper and set it aside.
- In a large saucepan, melt the butter over low heat. Once melted, add the marshmallows and stir continuously until they’re completely melted and smooth. This should take about 5 minutes.
- Remove the saucepan from the heat and stir in the vanilla extract.
- Add the crispy rice cereal to the melted marshmallow mixture and mix until well coated. Work quickly before the marshmallows start to set.
- Gently fold in the crushed Oreos, making sure they’re evenly distributed throughout the mixture.
- Transfer the mixture to your prepared pan. Use a piece of parchment paper or a spatula to press the mixture evenly into the pan. Don’t press too hard—keeping it a bit loose ensures maximum gooeyness!
- Let the treats cool for at least 30 minutes at room temperature before slicing them into squares.
- Store in an airtight container for up to 3 days (if they last that long!).
Cooking Tips & Techniques
- Don’t Overheat: When melting the marshmallows, keep the heat low to avoid scorching. Burnt marshmallows won’t taste good—trust me, I’ve learned the hard way!
- Prep Your Oreos: Crush them into chunks rather than crumbs to maintain that signature Oreo texture in every bite.
- Work Quickly: Marshmallow mixtures can set fast, so have everything prepped and ready before you start.
- Use Parchment Paper: This makes spreading the mixture into the pan much easier and prevents sticking.
- Customize the Crunch: If you prefer softer treats, use a little less cereal. For extra crunch, add a bit more cereal to the mix.
Variations & Adaptations
- Gluten-Free Version: Use gluten-free crispy rice cereal and gluten-free chocolate sandwich cookies instead of regular Oreos.
- Seasonal Twist: Swap Oreos for holiday-themed cookies (like peppermint bark Oreos for Christmas or pumpkin spice cookies for fall).
- Flavor Adjustments: Add a pinch of sea salt for a sweet-and-salty combination or drizzle melted chocolate on top for extra indulgence.
- Dairy-Free Option: Substitute the butter with a plant-based alternative and use dairy-free marshmallows.
I’ve even tried adding crushed pretzels to the mix for a salty crunch—it was a hit with my family!
Serving & Storage Suggestions
These treats are best served at room temperature, cut into squares and stacked high on a plate. Pair them with a tall glass of milk or a creamy hot chocolate for the ultimate indulgence.
To store, place the treats in an airtight container and keep them at room temperature for up to 3 days. For longer storage, wrap them individually in plastic wrap and freeze for up to a month. When you’re ready to enjoy, let them thaw at room temperature for about 30 minutes.
If you love your treats extra gooey, reheat individual squares in the microwave for about 5-7 seconds—it’ll feel like they’re fresh off the stove!
