This classic treat is even easier using marshmallow fluff. Anyone can make this and even the kids can help. If you love simple desserts like we do, this is a must try no bake recipe.

Not only is it so easy but it is frugal and tastes amazing. If you love Rice Krispie Treat Recipe, try this version with marshmallow fluff. The original recipe calls for mini marshmallows but I think you will love this version too.

What is marshmallow fluff?

Also known as marshmallow crème, it is a marshmallow spread used in place of marshmallows. The texture is different and does not provide the same gooey results as traditional marshmallows. Growing up, we love to make a fluffernutter sandwich with creamy peanut butter and marshmallow fluff.

However, it is just as delicious and so easy to use. We have a recipe for homemade marshmallow fluff if your store does not carry it. It is actually easy to make.

Ingredients

Ingredients for recipe: rice krispies cereal, butter, marshmallow fluff.

Variations and Additions

  • Mini Chocolate Chips. Fold in chocolate chips to make this classic recipe loaded with chocolate flavor. You can also melt the chocolate and drizzle over the bars.
  • Sea Salt. Sprinkle a pinch of salt on the bars.

How to make rice krispie treats with marshmallow fluff

  • Step 1. First, put the butter and marshmallow fluff in a small saucepan. Use medium high heat and stir constantly. Keep stirring until the butter is melted and the mixture is smooth. Remove from heat.

Step 2. Get out a large mixing bowl. Pour the cups of Rice Krispies into the bowl. Then pour the marshmallow creme mixture on top. Mix together until well coated.

Step 3. Finally, pour the crispy rice cereal mixture into a 9X13 prepared baking dish. I suggest spraying wax paper, parchment paper or the back of a spoon with non-stick cooking spray and using it to press the mixture into an even layer in the pan. You can also use a rubber spatula. Allow to sit at room temperature for about 30 minutes to 1 hour so the bars can solidify. Then just cut and serve these homemade rice krispie treats.

Storage

I recommend not storing this crispy treats recipe in the refrigerator as the bar will become dried out and not as gooey. Place inside an airtight container and allow the bars to stay at room temperature up to 5 days.

Expert Tips

  • Don’t overheat the mixture or they will be crumbly instead of gooey. This is very important to making sure the bars stay together after cut.
  • The mixture will need to be pressed down firmer than regular rice krispie treats made with regular marshmallows to pack the mixture in the pan. They definitely need more pressure applied.
  • You can also heat the marshmallow fluff mixture in the microwave. Place the butter and marshmallow fluff in a large microwave safe bowl. Heat in 30 second intervals, stirring between each interval until the mixture is melted and combined.
  • If you need a different size, you can also half this recipe for rice crispy treats. Just place the bars in an 8X8 or 9X9 baking pan if you prefer to make a smaller amount of Rice Krispie treats.
  • Add chocolate chip morsels to the top for a change. I like the mini ones. You can just sprinkle them all over the top after you put the marshmallow mixture into the pan.
  • Sprinkles make everything fun. Enjoy this treat for holidays, birthdays and special occasions by adding sprinkles on top. You can choose any color or type you like.
  • Cereal. You can substitute cocoa krispies or seasonal rice krispies to jazz this recipe up. Red and green make a fun substitution at Christmas.
