Rice Krispie Treats 

Before we dive into the recipe, it’s a good idea that we look at what we need to know about Rice Krispie treats first. Here’s some of the most important information you’ll need to know before you start out on your cooking journey.

What Are Rice Krispie Treats?

Rice Krispie treats are a popular dessert or snack option. Typically, these treats are made by using Kellogg’s Rice Krispies (or another brand with the same product) and blended together with margarine or butter, along with marshmallows.

Generally, they are only made at home, but you can now buy some store-made Rice Krispie treats. Mostly, these treats are made using the same ingredients and following the same recipe. 

Do I Need To Use Butter?

Of course this is the crux of the entire guide. You don’t have to use butter at all, and this could be for dietary purposes, maybe you’re running low on supplies or maybe for ethical considerations. 

However, while making Rice Krispie treats without using butter is a basic and easy modification, it’s not without its flaws. As there is no fat in the recipe, you notice some clear differences in the taste and the texture.

Generally, making these treats without butter will be much more messy than usual, so not only could this be a little annoying in terms of having sticky hands – but the pan will suffer as a result.

Therefore, you’re going to need to use something like a non-stick cooking spray onto the pan and the baking dish (unless you already have non-stick surfaces. If so, do not use cooking spray as it can ruin the pan/dish). 

In terms of taste, butter is one of the major reasons you get such a luscious flavor. So, a great fat-free and dairy-free substitute is honey. It has the sweetness that you’re looking for and conforms to your fat-free requirements. 

Will The Modification Make A Difference In Calories?

You may find that the substitutes you’re using reduce the overall caloric value of the treats – but this will depend largely on the rest of your ingredients, and of course, the serving size. If you want to reduce the calories further, consider sugar substitutes as well.

Okay, so now we understand a little bit about these treats, let’s dive into the recipe you’re hoping for. We hope you enjoy making these gorgeous treats! 

Complete Guide: Fat-Free Rice Krispie Treats Recipe Without Butter


  • 1 packet (283 grams) of marshmallows 
  • 2 tablespoons of honey (42 grams)
  • 6 cups of puff rice cereal (180 grams)
  • ¼ teaspoon of salt (1 gram) 

Note: you can use any “Rice Krispies” for this recipe, so we’ve labeled it as puff rice cereal. You may find the named brand has a better taste, but that’s for you to decide!


Start by preparing a 9×13 baking dish and spray it lightly with nonstick cooking spray. You may decide to use oil for this, but remember that oil might have a very small amount of fat in it. The same applies for butter or margarine – and this would be counterintuitive. 

Then, with a large saucepan, check to see if it has a nonstick pan. If it does, then there is no need to use any cooking spray or oil here as it can damage the pan. However, if it does not have a nonstick pan – then spray some nonstick cooking spray onto it.

Now, melt some honey over a low heat and mix in marshmallows and salt. Stir all of these ingredients until they are completely melted. 

Remove the pan from the heat and right away, stir in the puff rice cereal until you’ve completely coated them. 

Finally, pour in the mixture to a dish that you have prepared and then, using the back of a spoon, push the mixture down and allow the now flat mixture to cool for at least half an hour. After the mixture has cooled, you can then slice it into your chosen serving sizes.

Then all you have to do is store them into airtight containers – or eat them right away of course! 

Important Notes 

When it comes to using the microwave, simply use a heat-proof bowl and coat it with nonstick cooking spray. Microwave your marshmallows on a high setting for about 30 seconds at a time and stir thoroughly. 

To totally melt the mixture like this, it takes about two and a half minutes – and then you have to combine this with the syrup, puffed rice cereal and salt. 

Remember also, that without the use of butter – the mixture will be incredibly sticky, so cooking spray and/or oil is going to be essential. 

Finally, when you are cutting the finished and cooled treats, consider using a hot knife. You can do this by running the knife under hot water (then drying it) first – or holding a knife blade over steam (like from a kettle). Just be careful not to burn yourself in the process.
