Instructions
This recipe is simple and comes together in just a few easy steps.
Step 1 Create Treat. Melt your butter in a large saucepan. Once the butter is completely melted, add the mini marshmallows. Continue stirring over medium heat until the marshmallows are completely melted.
Fold in the peanut butter followed by the cereal and crushed Oreos. Make sure your cereal is evenly coated in the marshmallow mixture.
Step 2: Into the Pan. Spread your mixture into a 9x9 inch dish. Let your Rice Krispie treats cool on the counter for at least 30 minutes before slicing.
Recipe Tips
- Storage: Store airtight to maintain freshness on counter or in your refrigerator for firmer texture, for up to a week. Freeze up to 2 months and allow to come to room temperature before serving.
- Use mini marshmallows: If possible use mini marshmallows. They melt faster over low heat and are easier to measure than regular marshmallows.
- Use salted butter: Balances sweetness of marshmallows and cookie pieces. If you only have unsalted butter add ½ teaspoon of salt to the marshmallow mixture.
- Crush Oreos roughly: You can crush your Oreos as much as you'd like. I like to crush them roughly so there are a variety of cookie piece sizes scattered throughout the rice krispie treats.
- Cut with a sharp greased knife: Clean slices every time.

Recipe FAQs
No, leaving some larger chunks adds texture and visual appeal.
Avoid overcooking the marshmallows and store in an airtight container.
Yes, just chop them, cut them with scissors or allow extra melting time for even consistency.
The marshmallows were likely overcooked or cereal mixture was pressed too firmly into the pan.
