These rice crispy treats made with marshmallow fluff (also called marshmallow creme) are such an easy and delicious no bake treat!
While I usually use mini marshmallows in my rice cereal treats, I recently made a batch of Amish pumpkin whoopie pies that called for marshmallow fluff. I was able to use the leftover marshmallow fluff to make rice crispy treats and they turned out great.
Both my kids and my husband really love rice crispy treats and I love that they are so easy to make! Who doesn’t love a tasty, no bake treat?

Some people say it is rice crispie treats, rice krispie, or rice cereal treats. Rice Krispie is the name brand of rice cereal. All are correct when referring to these yummy treats!
📋 Ingredients needed for this recipe
I love that only four ingredients are needed. For this recipe, you will need:
- Marshmallow fluff: Also called marshmallow creme.
- Rice cereal: Such as Rice Krispies. I used a store brand without any problems.
- Butter: I recommend using unsalted since salt content can vary brand to brand.
- Vanilla extract: Pure vanilla extract is best. I recommend using it whenever possible.
🍽 What type of pan is needed?
You will need a 8 x 8 inch pan for this recipe. Be sure to grease it well.
🥣 How to make (step by step guide)
In a large pot, melt your butter on low. Once your butter is melted add in the marshmallow fluff and stir well over low heat (image 1). Stir slow and on low until well combined.
Once the marshmallow fluff is melted in, turn the heat off and stir in the vanilla extract. Pour the mixture over your rice cereal (image 2). Stir it together (image 3).
Gently press it into a well greased 8 x 8 pan (image 4). Cool for at least 2 hours before cutting and serving
👩🏻🍳 Tips for this recipe

💬 Recipe FAQs
Yes, you can use marshmallow fluff instead of marshmallows in rice crispy treats. The fluff is actually quicker to melt in with the butter.
Marshmallow fluff is a great substitute for marshmallows.
Marshmallow fluff tastes similar to marshmallows. It has a similar sweet flavor.
Rice crispy treats get hard if you press down on them too much when placing them in a pan. They will also harden in the fridge so I recommend keeping them at room temperature.

I made these last week for my teenage kids and their friends and they were a hit! First time making them in YEARS! Making them again today for our pumpkin carving party! One question I have is when are we supposed to add the salt?? Last week, I just added to the vanilla but didn’t see in the recipe where it says to actually add the salt.
Audrey says
Hi Stephanie, you can add the pinch of salt when you melt the butter 🙂 I’ll update the recipe to be more clear, thanks for bringing it to my attention. I’m glad you liked them!
Dan says
Thank you for including the “Jump to Recipe” link. Other sites make it very tedious to scroll through all of their fluff in order to see the recipe. If I want to read on the history of marshmallows I’ll Google it!
Audrey says
Of course, I’m glad you got to the recipe quickly. The extra information is there if people have questions 🙂
Alex says
Taste good but mine didn’t stick together. I have no idea what I did wrong. I followed the directions exactly and let them set for over 5 hours. I’m not sure if it’s because it was too hot in my house (summer in AZ 🥵) or maybe because I used generic rice brand rice cereal 🤷🏼♀️.
Barbara says
If I wanted to add peanut butter to this recipe how much should I use?
Audrey says
I haven’t tested this with peanut butter but you could experiment. I would recommend 1/2 of a cup of creamy.
Madeline says
Can I double this recipe and use a larger pan to make them thicker?
Audrey says
Yes, you can do that.
Lisa says
I put 1/4 to 1/2 cup of pnut butter in with the butter. Stirring constantly then add the crispy. I spread it out in a buttered pan and while it’s still warm sprinkle chocolate chips randomly around the batch. I don’t recommend spreading the warm chocolates around. It can dominate the flavor of the peanut butter if you have chocolate in every bite.
Mel woodling says
I’ve made these before but this is the first time using vanilla. So good.
Jen says
Very good recipe. I had some marshmallow cream in the pantry nearing it’s expiration date so figured I’d use it somehow and found your recipe. It’s been many, many years since I’ve made rice crispy treats so I kinda felt like a kid again while making them 😅😊. I added some chocolate chips and I melted the butter and marshmallow in the microwave in a glass bowl…only took 30 seconds. Thank you for the recipe 😊
Lisa says
EDIT:Add the marshmallow stirring until MELTED in with the butter and put butter. You can omit adding vanilla!!
