Ingredients and Substitutions
This rice krispie treats with fluff recipe requires only 5 ingredients to make and you probably already have them in your house. Make sure you have these ingredients ready to go.
- Rice Krispie Cereal: Feel free to use any rice cereal you like.

How to Make
Learn how to make Rice Krispie treats with marshmallow fluff in a few easy steps.
- Grease and line a 9 x 9 or 9 x 13 pan with wax paper or foil along the bottom and two sides of the pan. Alternatively, grease the pan really well. In a sauce pan or pot, melt the butter on low heat until the butter to begins to foam. Once it starts to foam, whisk or stir the liquid butter frequently. The butter will begin to smell nutty and very fragrant. Once the foam has subsided, the butter should have some brown, lightly toasted bits floating at the bottom. As soon as the butter has browned, add the marshmallow fluff. Stir continuously over low heat until the the fluff begins to pull away from the bottom of the pan.
- Stir in the vanilla extract and salt. Add the rice krispie cereal directly to the pan if possible. If not, make sure all the cereal is in a large bowl and pour the melted marshmallows directly into the bowl of cereal. Quickly and carefully stir the cereal and gooey marshmallow fluff together until well combined. Evenly scoop the gooey cereal treats into the prepared pan. Firmly press the fluff rice crispy treats into place.
3. Allow the treats to set for at least 30 - 60 minutes at room temperature or chill in the fridge until set. When the treats have set, then slice and enjoy.
How To Make Ahead, Store, Freeze and Thaw
- Make Ahead: Prepare the crispy treats with marshmallow fluff according to the recipe directions. Keep the marshmallow treats in the pan, fully wrap the pan in plastic wrap and store at room temperature for up to 1 day before serving for the best tasting treats.
- Store: These fluff crispy treats store well in an airtight container at room temperature for up to one week.

M’s Expert Tips

- Stir the fluff and butter constantly. Once the butter and fluff are mixed together, make sure to stir constantly. Keep the heat low and stir until the fluff begins to pull away from the bottom and edges of the pan.
- Prepare the pan. Lightly grease the pan with cooking spray or butter and line the pan with wax paper or foil before transferring cereal and marshmallow mixture into the pan.
- Fully cool the treats. For a quick cooling and setting time, transfer the treats to the fridge. Alternatively, allow the treats to cool at room temperature for an hour.

FAQs
Yes, you can make creamy and gooey crispy treats with fluff. A good ratio to keep in mind is 7 oz. marshmallow fluff is equal to about 4 cups of mini marshmallows.
This typically happens when the marshmallows or in this case, marshmallow fluff are cooked over high heat or when left on the heat source too long. Cook the fluff with the butter over low heat and only as long as needed for the fluff and butter to mix well together.
