Ingredients in Weight Watchers Rice Krispie Treats
- 4 oz Zero-sugar marshmallows
- ½ tsp Vanilla extract
- 3 tbsp Light butter substitute
- 2 ½ cups Rice Krispies or other crispy rice cereal
- 2 oz Optional: Lily’s dark chocolate baking chips to melt for garnish (adds 1 WW point per serving)

Instructions for making Weight Watchers Rice Krispie Treats
- Place a pan over medium heat on the stovetop and gently melt the butter. Add the vanilla extract and the marshmallows.

2. Continuously stir the mixture to melt the marshmallows completely.

3. Turn off the heat and add the Rice Krispie cereal. Fold the mixture to coat the cereal entirely with the marshmallows and butter.

4. Working quickly, transfer the Rice Krispie mixture into a greased 8 x 8 baking dish and use a rubber spatula to press it into the pan. You want it to be very compact so that it doesn’t crumble when you cut it.
5. If using chocolate, melt it in the microwave in short 10-second spurts until smooth. If it seems too thick, you might need to add a small dash of vegetable oil. I personally like to transfer the melted chocolate to a small piping bag so I can drizzle on lines rather than try to spread the thick chocolate with a knife.
6. Decorate the Rice Krispie treats with the chocolate garnish and then place them in the refrigerator for about 15 minutes so that they can firm up and the chocolate can harden. If they seem crumbly around the edges, you can put them in the freezer to firm them up even more before you remove them from the pan.

Variations and Substitutions
- Zero-sugar vs. Regular Marshmallows: If you can’t find a sugar-free option, you can certainly use regular or mini marshmallows. Depending on the type you use, it will likely increase the Weight Watchers points by one or two points per serving.
- Using Real Butter: I like to use “I Can’t Believe It’s Not Butter, Light” because it still has a buttery taste even though it is lower in points. However, you can also use real butter instead of a butter substitute. You’ll need to adjust the recipe using the Weight Watchers recipe builder to see the WW points amount.
- Rice Krispies with Sprinkles: My suggestion is to scatter sprinkles on top after you press the treats into the pan. In my experience, if you mix in the sprinkles too early, they will melt from the heat and discolor the Rice Krispie treats. So, if you want them mixed in, just be gentle and wait until the last minute.
- Other Variations: feel free to mix in some peanut butter or use a different flavored extract rather than vanilla extract. There are plenty of ways that you can switch this recipe up. You can also garnish it with chopped nuts, toasted coconut, or white chocolate rather than dark chocolate.
- 9 x 13 Pan: Double the recipe to make this in a 9 by 13 pan. This will give you 15 to 18 servings depending on how you want to cut it.
Tips and Tricks for Making Weight Watchers Rice Krispie Treats
- If you don’t mind the Weight Watchers points increase, you can add more marshmallows for chewier Rice Krispie treats. I personally love the texture of these, as they are soft and chewy but also firm enough to hold their shape!
- Don’t use high heat. When heating the butter and marshmallows, just use low to medium heat, and don’t try to rush the process. They melt down quickly anyway. You don’t want to risk burning the marshmallows and giving your Rice Krispie treats an unpleasant taste.
- Make sure to press the Rice Krispies treats firmly into the pan. One of the most important things is making sure that the Rice Krispie treats are compact. Otherwise, they will fall apart when you try to lift them.
