How to Make Oreo Krispies
Prepare the Dry Ingredients
In a large mixing bowl, combine the Rice Krispies cereal, crushed Oreo cookies, and 1 cup of the mini marshmallows.
Mix gently so the Oreo pieces are evenly distributed throughout the cereal.
Melt the Marshmallows
In a large saucepan over medium heat, melt the butter completely.
Add the remaining 8 cups of mini marshmallows along with the salt. Stir continuously until the marshmallows are fully melted and smooth.
Tip: Keep the heat at medium or slightly lower to prevent the marshmallows from becoming tough.
Combine Everything
Pour the warm marshmallow mixture over the cereal mixture.
Using a rubber spatula, gently fold everything together until every piece of cereal and Oreo is coated.
Work quickly before the marshmallow mixture begins to set.
Press into the Pan
Transfer the mixture to a lightly greased 9-inch square baking pan.
Using the spatula or lightly buttered hands, gently press the mixture into an even layer.
Avoid pressing too firmly, as this can make the bars dense instead of soft and chewy.
Cool and Slice
Allow the Oreo Krispies to cool at room temperature for about 30 minutes.
Once set, cut into squares and serve.

Tips for Success
- Use fresh marshmallows for the softest, chewiest texture.
- Crush the Oreo cookies into medium-sized pieces instead of fine crumbs for more texture.
- Stir gently to avoid crushing the cereal.
- Lightly grease your spatula to prevent sticking.
- Don’t overheat the marshmallows, as this can make the treats hard.
- Let the bars cool completely before slicing for clean edges.
Equipment Needed
- Large mixing bowl
