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!

Yield: 16 servings
Serving Size: 1 piece


  • 2 tbsp light butter spread, I used Smart Balance Light

  • cooking spray


  • Spray a 9x12-inch pan with cooking spray and set aside.
  • Heat a large saucepan on low heat.
  • 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.
  • Add Rice Krispies to the melted marshmallows, and stir until completely combined (this is the hardest part, do this quick before the marshmallows cool).
  • Press into the buttered pan with wax paper and cut them into 16 pieces.

  1. I made these for Halloween, cut them out with cookie cutters, and lightly dusted with colored sugar! They were yummy and festive! 
    I am wondering if you have ever tried to make a light version of Nutella Rice Krispies? I would love to see your skinny version!!

    Yes I did make recipe. Very light and scrumptious. I have Chrons and it one of the only desserts I can have.

  3. Made these tonight. Used a 10 oz bag of Mini Marshmallows. According to the nutritional information on the bag, this amounts to 6 cups not 4 cups (2/3 cup per serving x 9 servings per bag).  So I wasn’t sure whether to measure 4 cups of marshmallows or use the whole 10 oz bag. Decided to use the whole bag, and they turned out great!  Was I correct?

  4. I just wanted to comment that I made this recipe with coconut oil instead of margarine and they came out great! I sprayed my casserole dish (9×6” I think?) with Pam spray and cut into 12 squares. Fantastic! They are not rubbery or hard, just perfect. Thank you for the light recipe! Will make again 🙂

  5. I did make them & they were delicious!!!! I highly recommend them. I am a weight watchers & I love marshmallows. I made them to bring to a music festival/camping trip & they were great to have a great without paying big money for something I’d feel sorry for eating. Thank u, skinnytaste!! Getting ready to make another tray now.

  6. I made these yesterday. I still can’t get my head round the fact that they are so low calorie. As for the butter-v-marge debate. I used Tesco Butter Me Up Light spread and they were not at all rubbery or soggy, just crispy, light, sweet and delicious. I also added a few sultanas. May add some choc drops next time.

    Oh, I love you! I’m about to try those Rice Krispy sushi I saw on Pinterest by, and the original Rice Krispy’s recipe in its site warns not to use light or diet butter.  I was googling what would happen if I did (it’s all I have in my house!) and saw my beloved Skinnytaste in the results! 

    What?!?! She’s done those too??  I’m getting ready to see if they work out!  If they don’t work out well for rolling sushi, It’ll be like he majority of my Pinterest attempts and we will laugh and laugh, and know that it’s because I have 10 thumbs, zero patience, and the attention span of a 2 year old.

    Anyway, back to work for me. I have a birthday party to put together!

    Thanks again!

    If you are vegetarian, you can use a jar of marshmallow fluff in stead of
    wholee ones, always works for me

  10. OMG, These are sooooo GOOD! I was a little, ok a lot lol, hesitant about making these after I read a few comments about these coming out soggy. Boy am I glad I made these! I used Smart Balance spread, I made sure I also sprayed the sides of the pan I heated the Smart Balance and marshmallows in with cooking spray, and also the spatula I used to mix, etc. Easy to make, No mess, and taste great!

    Btw, I'm one yr post-op (Gastric Bypass) so there's a lot I can't eat (well I could but would make me sick so I choose not to be sick!), I was able to eat this without any problems, Therefore not depriving myself of a treat. Thank you for this recipe 🙂

      That's great!!! So glad you liked them and that you didn't let other people's experiences stop you from trying! Awesome

  11. I've actually never made rice krispy treats but needed to use up a bag of marshmallows so I went looking for how to make the treats and found this recipe. They turned out perfect. No problems, not soggy, just yummy. Thanks.

  12. Tried them with the sultanas & cherries, substituted 1 spoon of the spread for 2 of runny honey & added some dessicated coconut – heavenly!!
