Low Fat Rice Krispy Treats

This post may contain affiliate links. Read my disclosure policy.

These low fat Rice Krispy treats will satisfy your sweet tooth, and your kids will enjoy them too! I replaced the butter with Smart Balance Light and used half of the required amount. I’m not a big fan of making sticky things, and I’m not sure if it gets stickier than melting marshmallows and combining them with puffed rice, but it’s so worth the getting your fingers sticky for this low fat, low point dessert. No baking required!

  • Spray a 9x12-inch pan with cooking spray and set aside.

  • Melt butter spread being sure to coat the bottom of the pot to prevent sticking.
  • Add marshmallows and melt on low flame.
  • Stir until completely melted, then remove from heat.

  1. I used a low fat olive spread & also added sultanas & chopped glace cherries for added sweetness & texture. They were delicious – ate far too many. Made them to take to work & sprinkled with white choc chips before chilling.

  2. Wow. I made a batch last night and everyone loved them! They were crunchy and soft at the same time. Not soggy at all! Thanks for sharing!

  3. I made it with gluten free rice crispies, low calorie/fat margarine and used a little less marshmallows =) yummy!
    Not hard at all. Delish!

  4. Friendly FYI – marshmallows are not vegetarian, they're made with gelatin. Just in case someone makes this for a veg friend!

  6. Just made these and they came out DELISH!! I added two cups of fiber one (no marshmellow adjustments or anything) and they came out soft, not soggy at all. I pressed them into a sprayed pan with wax paper, and then cut them into 20 pieces. It came out to 2 points each piece. Bigger than the WW bars, but just as many points!

  7. Made these with my 4 and 6 year old. They loved them 🙂 thanks for remining us wevcan still enjoy junk by modifying recipes w/ lighter options. 🙂

  8. Umm this is the normal way of making them. unless all you normally eat is super fat butter. lol…

  9. Made these and the bangin shrimp at my good friends house tonight (she's a fellow weight watcher). Her 2.5 year old daughter helped me make these and she had so much fun. They were so good and easy to make. My friend's husband didn't even realize they were "light" – he said they were the best he had because they weren't too gooey but just perfect. Definitely will be making again!

  10. These were absolutely delicious and SO EASY! I've always been hesitant to make them because they sound so crazy, but they were really great!

    I subbed in brown rice crisps that I found at Whole Foods and they were amazing! I added them into my Weight Watchers calculator and it came out to 3+ but I still totally love these!

  11. My kids WILL NOT go back to packaged rice krispy treat after making these. We are making these about once a week because now my husband is eating them all:) Family favorite and I actually have my 6 and 8 yr old make them while I supervise.

  12. I made these with Fleischmans margarine (with olive oil) and so did my own calculations for calories as I also used the large m.mallows and may have put in a bit extra. I came up with 107 per piece but oh what a good piece it was! I truly did not notice the missing butter. So soft and gooey! My son and I ate them right after so I don't know how they'll taste tomorrow….hmm I may never find out! thanks for ANOTHER successful recipe!

  13. I can't believe I did this. I added Better than Peanut Butter instead of the Smart Balance. My kids loved it! Should be the same points too.

  14. Just made these tonight and they taste just as delicious as if you were using the real recipe with butter! I just joined weight watchers and came upon your site, I love all of your recipes and cannot wait to cook for superbowl and trick all the males with your low fat recipes! This diet will be manageable thanks to you!

  15. I have been making these for months. I love them. Too many marshmellows are way over rated. I am going to pass this recipe onto some of my friends trying to watch their weight.

  16. Just made them … DD loves them! I used Land O'Lakes Light Butter (not in a stick) and they came out great!

    I might try the canola oil trick from one of the posters up above sometime.

    Thanks Gina! I don't know if you realize how much we talk up this site on the WW Newbies message board! 😀
