Rice Krispie treats are an American classic…a tried and true favorite of millions of people. Normally, it wouldn’t be a good idea to make changes to such an iconic recipe, but that’s exactly what I did! Many, many years ago I made a few tweaks to the original recipe, and I’ve been making that version ever since.

The original recipe on the box of Rice Krispies calls for 3 tablespoons of butter, a bag of marshmallows, and 6 cups of Rice Krispies cereal. I changed those ingredients to 4 tablespoons of butter, a large container of marshmallow creme (sometimes referred to as fluff), and 8 cups of Rice Krispies. Not a huge change, but one that has a big impact on the taste and texture of the treats. 

Tips for Amazing Rice Krispie Treats

  • It takes patience, but make sure to get all the marshmallow fluff out of the jar or container. A rubber spatula works best. It’s sticky, but totally worth the effort!
  • When heating the butter and fluff, stir constantly. When it smooths out, and begins to pull away from the bottom of the pan, it’s ready. Do not overcook…it doesn’t need to be piping hot.  
  • It’s important to firmly smash down the warm cereal/fluff combination after pouring it into the 9 x 13 pan. A large stainless steel spoon works the best.

What You Need to Make Rice Krispie Treats

When my son was in high school, he was a 4-year member of the golf team. When he was a freshman, for his very first away match, he asked me to make cookies for the road trip. I made a batch of chocolate chip cookies and a batch of these rice krispie treats. The boys loved them so much that I was nominated for snack duty for the rest of his high school career! I was working full time at the school then, and believe me there were times when I was in the kitchen until 10 P.M. I loved it though, and disappointing those boys was never an option. I’ve said this before, but I so wish I could go back, and have just one of those nights when I was up until 10 p.m. making snacks. 

You really can’t get more classic than Rice Krispie Treats…or more delicious. You certainly can’t get much easier. I really hope you give these a try. Your family will think you’re wonderful!

Until next time…

    Absolutely Love these they turned out great!!!

  2. 5 stars
    To give the extra “crunch” many say is not there without the gelatin found in marshmallows, I melted in a box of soft Werther’s caramels (about 20) and super compressed the treats with a spatula. EXCELLENT.

    Wow! I love how these ended up looking. I always want extra marshmallows in my rice crispies and this recipe nailed it!! I am totally pinning this for later. I might just make it very soon

    These were AMAZING!!! I am going to make my regular rice Krispie treats like this EVERY time from now on!!! So delicious!! Thanks for the FABULOUS recipe!! YUMMY!!

  8. 5 stars
    I love that these treats taste great but aren’t as chewy. I have dentures and always have to worry about eating sticky foods. These were perfect for me.

  9. Nancy Scoble says:

    * It would be nice….
    Even outstandingly above the board, if an actual measurement of the dry cereal were given as an option.

    I made mine rice crispy bars…… I am okay with a “that should work” attitude but I, for sure, am not driving back to the grocery store for Marshmellow Fluff.

    1. Ann Drake says:

      Hi Nancy…I’m sorry, but I’m confused. I give the dry cereal measurement in the recipe as 8 cups. I’m not sure what you mean by a “that should work” attitude? Please let me know if you need anything else. Thank you, Ann

      Appreciate your simplicity without sacrificing taste! Thank You
      I had extra Nutella and peanut butter so i frosted them….
      They look delicious…..

  10. Just made these and they are great! Allows me to make rice krispy treats that are easy and vegetarian, and which I love!

  11. 5 stars
    I. Love. You. Just made these and they are awesome!!!!!!

  12. 5 stars
    Sound great. I love your recipe. It’s simple and effective. I usually eat it in the morning. It was delicious. Is it okay if I add more butter to the recipe? What do you think?

  13. Cynthia Topps says:

    I make this treat and use it as the sandwich for an ice cream sandwich.
    My mother used neopolitan ice cream but I like Vanilla chocolate swirl.
    What you do is divide your batch of krispies into two thinner batches. Then once they are set spead the ice cream on top of one and place the other on top of that. Then cut and enjoy.

    1. Ann Drake says:

      Sounds delicious Cynthia…thank you for sharing!

    I tried this recipe today. I only used half of the ingredients because I only had 7 ounces of marshmallow creme and they turned out great! Light and fresh. My family loved them. Thank you

  15. 5 stars
    Easy and quick! I used 1 cup less cereal to make the treats extra gooey.

  16. marlene jones says:

    I made these and they just crumbled when I tried to get them out of the pan. The fluffy is lovely but it think they need the structure of the marshmallows to kind of glue them together. Thanks for recipe though.

    1. Ann Drake says:

      I’m sorry! It’s important to really smash the rice krispies down firmly in the pan…I have made these literally dozens of times and that has never happened.

  17. Amanda Smith says:

    Just now making them my hour is up at 9 … I’m so ready they do look delicious 😋

  18. marlene jones says:

    Oh yes yes yes. I made these today. But i go a bit crazy and make my own fluff. Its so airy and wonderful. But i didnt have this recipe to know i needed extra cereal in the treats. So mine are quite loose. Ahhhh live and learn. I have always added extra butter anytime i have made these either with marshmallows or the fluff. Its so nice to give my family a tasty treat that has ingredients in it that I know wont harm them. Thank you so much for taking the time to give us wholesome recipes.

  19. I made these yesterday but they did not set. When you try to cut them or pick some up the fall apart in your hand. What did I do wrong?

    1. Ann Drake says:

      Hi Mitzi…I am sorry! This has never happened to me. It does take a while for the pan to set up…probably at least an hour or two. They are very soft, but they should not fall apart. I hope this helps!

  20. Rice Krispie treats. Yum yum yum. Hated melting the marshmallows. Very clever to use fluff. Tomorrow is shopping day and these will be added to my list. I am thrilled.

  21. I always add 1/2 cup of peanut butter to mine. That way I can say it’s healthy because of the protein.

  22. This makes my mouth water just reading about it😍 Definitely trying this out!

  23. Kittyluvr says:

    Love this story!!! My husband played high school and college golf…I am sure he would have shot an even lower score had he been fortified with these yummy goodies! I am making some this afternoon. I have always hated melting the marshmallows and stirring forever. This sounds great!

  24. My husband is the chief rice krispy maker in our home and he always has used marshmallows. I will suggest the marshmallow creme for the next batch. Not sure how it is in your home but we still have a debate on whether this candy should be more crunchy or more soft. How about you?

  25. Carole Strawn says:

    I love Rice Krispie Treats and I haven’t been a kid for 60 years! I’ll have to try your recipe. Certainly seems easy enough. Yum!

  26. I made these yesterday and they are hard and crispy. I am wondering what could have went wrong. Do you think I melted the marshmallow cream at too high heat or I even thought of using less rice krispies. I am going to try again.

    1. Ann Drake says:

      Hi Sara…honestly, I’m not sure. I have made these dozens of times and they turn out every time. The marshmallow cream only needs to be melted…it doesn’t have to be very hot to still mix up well. Once they set up, they are definitely firm but still sort of chewy.

  27. I only had one small jar of marshmallow fluff so I halved the recipe and it turned out well. Also you should try it with the chocolate Rice Krispies… amazing!

    1. KittyLuvr says:

      What a great idea!!! YUM!!!

  28. Thanks for the recipes, Ann

    Pink Hugs,

  29. Mila Bassett says:

    My 4 year old and I just watched the video and decided that’s what we are going to be making for our treat tomorrow. She figured out what the steps and the ingredients are. Can’t wait to get started!

  30. Thank you so much, your site is awesome, so many great ideas. I belong to a ladies homemaker group and we are always looking for inspiration.

  31. Quick question, about how many servings does this recipe provide??

    1. Ann Drake says:

      It fills a 9 x 13 pan so it depends on how big you cut the squares. At least 12 but if you made the squares smaller there would be more. I usually cut mine into 12. Thanks for stopping by!

  32. Thank you so much for this recipe! Our 3 year old daughter is allergic to beef (aka gelatin, aka marshmallows) as a result she has never had rice krispy treats. I am super excited to make these for her. Thankfully marshmallow cream doesn’t have gelatin.

    1. Ann Drake says:

      This makes me so happy Stacy…thank you for taking the time to tell me. I never in a million years thought about it being an answer to an allergy issue. Have fun making them for your daughter!

  33. Stacey Haralson says:

    I make my husband Rice Kripsy treats every year for Valentine’s day and we have been together 23 years. I really don’t like to make Rice Kripsy treat with the marshmallows because if they are old the treats get hard the next day and it is hard to get all of the treats out of the pan. I was excited to see this recipe because I didn’t want to go buy marshmallows and I had to jars of marshmallow cream. They turned out excellent and so much easier and I think quicker. Thank you so much for sharing this recipe.

    1. Ann Drake says:

      Hi Stacey! I’m so glad you liked my version of RKT. They really are so much creamier and I agree they are easier too. Thanks for taking the time to let me know! ~Ann

  34. I’m back after making these last night and tasted them this morning. WOW! They are the best ever!! Will never make them any other way. Thanks so much for this recipe!!! The basketball players are gonna love them!

  35. Just made these and they look wonderful! My daughter is a cheerleader and each week we make treats for the basketball players. I spotted this recipe with the marshmallow fluff and decided to try. I also made a batch for us. Big difference with how much nicer it was to work with and the appearance is just great! This will be the only way I will make them from now on. Thank you!! I know they will be hit!

  36. These look great! How long do they stay soft/fresh?

    1. Ann Drake says:

      Hi Kerri! Honestly, my family always ate them so quickly they never had time to get stale! If you keep them in an air tight container they should stay fresh for several days. At least 3 and probably more. Thanks for stopping by!

  37. Sometimes I put a small box of strawberry jello in the marshmallow and stir until it dissolves. That tastes really good too. Use different flavors of jello. Yummy

  38. Crystal Wonitoy says:

    I always add a teaspoon of Madagascar Vanilla to mine – yum!

  39. Do you spray the 13×9 pan?

    1. Ann Drake says:

      Hi Dawn! No I don’t. Once the cereal set up the squares come right out. Thanks for stopping by!

  40. Funny, I add a heaping tablespoon of marshmallow cream to mine but never thought to use only marshmallow cream. Now I will. Thanks and happy Saturday!

  41. Hi there. How many cups of marshmallow cream do you think would be in the container you use. Where I’m from we only have one sizethat looks to be about one and a half to two cups of marshmallow cream.do you think that would be enough? I really want to try your version – it sounds delicious! Thank you so much!

    1. Ann Drake says:

      The container I use is 13 oz. A little more or a little less won’t make a difference. Enjoy!

      1. I have made the rice krispie treat like on the box. Then put half of the Krispie mixture in the pan then spread the marshmallow Creme on top of the krispies and then spoon the rest of the Krispie mixture on top of that. That also makes a fun creame sandwich.

  42. You say margarine, but the picture shows butter. Which do you use?

    1. Ann Drake says:

      The recipe says butter or margarine. It really doesn’t matter. I use butter because that’s all I buy. Thanks!

  43. Ricki Jill Treleaven says:

    My 16 year old loves these…they’re her favorite treat, so you’re her favorite blogger of the moment. ;P

    Thanks, Ann!

  44. Ashley@AttemptsAtDomestication says:

    Oh I love Rice Krispies treats! Now I really wish I had some to snack on!

  45. Making these for my grandkids tomorrow since they have the holiday off. Water heater died yesterday. Thank goodness my daughter lives nearby.

  46. I haven’t made rice krispie treats in so long! I love them. My youngest son isn’t a fan of them if you can believe that. That’s probably why I haven’t made them in so long. You’re right though, they are such a classic. I love eating them warm right after they’ve been spread in the pan. Yummy!

  47. Jane @ Cottage at the Crossroads says:

    Ann, I am drooling on my laptop! These look so good. Would you believe that I have never made these! I’ve eaten plenty, though, and substituting the marshmallow creme sounds like such a good idea. I’ll have to make these for the grandgirls when they visit so I’m pinning the recipe!

    1. Ann Drake says:

      Oh those girls will eat the whole pan! They could probably make them on their own if you are there to supervise. lol. Thanks for stopping by!

  48. Michele/Finch Rest says:

    Yum, I love these treats. I also add vanilla to mine – and usually add sprinkles on top to make them festive.

    May have to make these soon, haven’t since waaaay before Christmas.

    Have a nice weekend, Ann.

    1. Ann Drake says:

      I will have to add the vanilla next time. Thanks for stopping by Michelle! Hope you are keeping warm…Ann

  49. Grace @ sense and simplicity says:

    Isn’t that funny, but I never thought of using the marshmallow creme to make the squares. I can believe they are creamier. Thanks for the tip.

  50. We are huge RKT fans here and I can’t wait to take your recipe for a spin. Yum!!

  51. Sharon @ The Blue Willow House says:

    Yum, I’m going to try your recipe.

  52. I sometimes make them this way!

  53. Kathleen G says:

    I used to make fudge with the marshmallow cream. This sounds scrumptious. Making them for your son after a day of work does not surprise me. You sound like a loving mom. Have a nice weekend. Kathleen in Az

    1. Ann Drake says:

      You too Kathleen…enjoy your weekend. I would bet that your weather is a whole lot better than mine!

  54. That’s how I make them too :)

  55. Chloe Crabtree says:

    Thanks for sharing this interesting idea for adjusting this old standard. I will have to try this. I can certainly relate to you about the willingness to go back to those days when the house was full of teenagers and they all wanted homemade cookies. It warms me a little bit inside when my son who is all grown up and lives in New York City tells me he would really like some of my homemade snickerdoodles. I am more than happy to oblige and send them off in the mail.

    1. Ann Drake says:

      Oh my son loves snickerdoodles too. Thank you for taking the time to leave such a nice comment!

  56. Hi, THIS is the recipe my Mom made as I was growing up in the 50s & 60s…I didn’t even know some people used marshmallows!! Glad I didn’t or I would have wasted a lot of time & energy.
    Have you tried versions using peanut butter, or chocolate chips. Easy and the kids love them.

    1. Ann Drake says:

      I have never used choc. chips but have made the peanut butter ones with the chocolate layer on top. My kids, given the choice, would always choose the plain old basic ones!

  57. Angie Lawson says:

    Oh boy these look delish!! Thanks for sharing the recipe, I am FOR SURE trying it. All of my kids go gaga for rice krispie treats, and they are super easy. That’s a neat story about your son! My oldest is a freshman, and maybe I can make these for some of his games!☺

    1. Ann Drake says:

      Enjoy the high school years with your son. Be careful though. Blink and they will be over!

  58. My family loves Rice Krispies Treats, including myself and I will definitely try your version. I made egg salad yesterday and followed your method for boiling the eggs, and they turned out perfectly. Thanks so much!

    1. Ann Drake says:

      Hope your family likes these as much as mine. Egg salad sounds wonderful. I am getting pretty bored with my same old lunches so I may make some to switch things up a bit! Have a good weekend Deni!

  59. Thanks for sharing your cooking secrets. I know what you mean about going back to those fun memories with our children. On to making more memories …

    1. Ann Drake says:

      Yes that’s what I keep telling myself. Don’t look back. Look ahead. Have a lovely weekend Janice!

  60. Pamela Gordon says:

    This is a nice switch on the recipe and sounds good. I have a bag of marshmallows that need to be used up soon so guess I could make the original recipe if I buy a box of the cereal. We just don’t eat too many of these treats and I haven’t made them in years! Enjoy the weekend.

  61. We LOVE making Rice Krispies treats at the Hines’ house!!
