Ingredients
- Butter: 4 tablespoons of salted butter to add rich flavor and help melt the marshmallows smoothly.
- Mini Marshmallows: 8 cups of soft marshmallows that create the chewy, sticky base binding the ingredients.
- Rice Krispies Cereal: 6 cups for crispy texture and the familiar puffed cereal crunch you love.
- Oreo Cookies: 1 cup of whole Oreo cookies crushed for maximum chocolatey, creamy cookie goodness in every bite.
- Salt: A pinch to balance sweetness unless you use salted butter, enhancing overall flavor.
Instructions
- Melt Butter and Marshmallows
-
In a medium saucepan over medium heat, gently melt the butter until bubbly. Add the mini marshmallows and salt, stirring continuously until the mixture becomes smooth and creamy. This creates the sticky, chewy binder that holds everything together.
- Combine Cereal and Crushed Oreos
-
Transfer the Krispie cereal and crushed Oreo cookies into a large mixing bowl. Mixing the crunchy cereal with Oreo chunks ensures every bite bursts with flavor and texture variations.
- Mix Marshmallow Mixture with Dry Ingredients
-
Pour the warm marshmallow mixture over the cereal and Oreo cookie mixture. Gently fold with a spatula to evenly coat all pieces without crushing the Oreos, achieving a balanced texture throughout.
- Press Mixture into Pan
-
Grease a 9-inch square pan and transfer the mixture into it. Press down evenly with a spatula or wax paper to compact the treats, helping them hold shape after cooling.
- Cool and Cut into Squares
-
Allow the pressed mixture to cool at room temperature for about 30 minutes. Once firm, use a sharp knife to cut into 16 bite-sized squares perfect for serving or packing as a snack.
- Use salted butter unless otherwise noted, to enhance the sweetness and flavor richness.
- For best texture, avoid overmixing so Oreos stay chunky instead of pulverizing.
- Fully cool before cutting to ensure clean edges and prevent crumbling.
Storage Tips
Store Oreo Krispies in an airtight container at room temperature for up to 3 days to maintain crispness. For longer storage, freeze in a sealed container for up to one month and thaw before serving.
Serving Suggestions

- Use mini marshmallows for even melting and better texture binding.
