Rice Krispie treats with marshmallow fluff are an easy, no-bake recipe that uses marshmallow fluff instead of traditional marshmallows, making the process even easier.

I don’t know why I didn’t think to use marshmallow fluff to make rice krispie treats, sooner!
It was a habit to make classic rice krispie treats using marshmallows but saving a step of melting the marshmallows, makes so much sense. Plus, the marshmallow creme makes them extra soft and gooey!
Marshmallow fluff remains soft and spreadable at room temperature, so it blends with butter perfectly, allowing for a deliciously chewy treat that holds together without becoming too firm or sticky.
Whether you’re making these for a party, easy dessert after dinner, or just to satisfy a sweet craving, they come together in under an hour and are loved by everyone.

Tip: Don’t press the mixture too much – Pressing the mixture down in to the pan too much, will make the treats dense instead of light and chewy.
Recipe Tips
- Use Fresh Marshmallow Fluff: Older fluff can become hard, or really stiff, so this would make stiff, hard, rice krispie treats.
- Control the Stickiness: Use wax paper to press the treats down in to the dish, or lightly wet hands with water or nonstick cooking spray before pressing down the treats to prevent the mixture from sticking to your hands.
- Allow to Fully Cool: Allowing the treats to fully cool will help make sure that the treats don’t fall apart.

Storage Tips:
Important: Storing these improperly will cause the treats to dry out and they’ll no longer be soft and chewy.
Place the marshmallow fluff treats in an airtight container or bag for best results when storing.
