Made using just three ingredients, they’re a simple, no bake treat that’ll have everyone reaching for just one more slice.

What are Rice Krispie treats?

Rice Krispie Treats, also known as Rice Krispie Squares, are a sweet, no bake slice made using butter, marshmallows and rice cereal. Here in Australia, Rice Krispies are called Rice Bubbles and these treats are packaged as LCM’S at our local supermarket. Confusing right?

tips for making the BEST rice krispies

  • Use a fresh, unopened box of Rice Bubbles or Rice Krispies
    Ever had a stale or soggy Rice Krispie Treat? Even if you’ve only opened a box a few days before, don’t be tempted to use it. For the perfect, crispy treat, I highly recommend using a brand new box of cereal for maximum freshness.
  • Use a baking scale to measure your ingredients
    The perfect Rice Krispie Treat requires the perfect ratio of butter to marshmallow to rice cereal. Too much marshmallow and butter can make a super sticky, wet or soggy slice, while too little makes a hard, dry or crumbly one. I recommend using a baking scale for my recipe to get the ratio JUST right, creating the perfect chewy but crispy Rice Krispie Squares.
  • Spray your spatula with oil or wet your fingers
    Melted marshmallow = sticky mess. But don’t worry, I’ve got a couple of tricks up my sleeve to help! Once you mix together the melted marshmallow and rice cereal, pour the mixture into a baking pan you have lined with parchment or baking paper. Then lightly spray your spatula with oil. You should be able to use it to press the mixture down without it sticking. Then, wet your fingers and use them to press down any lumps and bumps and neaten up the edges.
  • Don’t press down too hard
    While you do need to press the mixture into the pan, try not to press it down super hard. It’ll just make your Rice Krispie Treats hard and dense. You still want them to be light and chewy.

How to make Rice Krispie treats

  1. In a large mixing bowl, measure out your rice cereal and set aside. Use a baking scale if you can!
  2. Add butter and marshmallows to a medium saucepan. Place on a low heat. Stir gently while butter and marshmallows melt. Mixture should be creamy and smooth.
  3. Once the marshmallows have completely melted, pour over rice cereal and mix straight away. Mixture will be sticky, but keep mixing as best you can, until cereal is completely coated.
  4. Pour mixture into a baking pan lined with baking or parchment paper. Lightly spray a spatula with oil and use it to gently press down mixture, getting right into the corners. Wet your fingers with water to smooth over any large gaps or holes.
  5. Leave to set for at least two hours. Then slice into squares to serve. Rice Krispie Treats are best kept at room temperature in an airtight container. While they will keep for a few days, they are best enjoyed on the day they are made.

Commonly asked questions

Can I use mini marshmallows?

Yes you can. But if you do, I recommend using a baking scale to weigh them so you use the exact right amount.

Can I make these using a microwave?

Yes. You can melt the butter and marshmallows in the microwave, just make sure you stop and stir regularly – every 20 to 30 seconds. Stop when the marshmallows are almost melted and stir by hand until smooth. If the mixture is very hot, let it cool for a minute or two before adding to the cereal. But don’t wait too long or the marshmallows will start to set.

Do I have to add butter?

Yes I highly recommend it. You’ll get a more flavourful slice with a nice gooey texture.

Why are my squares dry and hard?

Make sure you don’t press down too hard when putting them in the baking pan. Also check your measurements (using grams if you can) to make sure you didn’t add too much rice or too little marshmallow.

Why are mine so sticky?

This recipe uses plenty of butter and marshmallows for flavour. Both also give the bars their ‘chew’ and gooey texture. Once you’ve added the melted marshmallow, make sure you stir the mixture really well so the cereal is evenly coated. Also make sure you leave the bars for at least 2 hours for the marshmallow to set.

Mix it up

While I really wanted to share a recipe for Classic Rice Krispie Treats, you can get creative with the toppings. Consider dipping them in chocolate, or adding a handful of chocolate chips or sprinkles on top before they set. Swap the butter for peanut butter or use coloured marshmallows for a festive treat.

Notes

Rice cereal: It’s important to use a fresh, unopened box of cereal for maximum crunch and chew. Stale rice cereal will go soggy and taste, well, stale!

Marshmallows: I tested this recipe using Pascall’s regular marshmallows. You can use mini marshmallows if you prefer, butI recommend using a baking scale to weigh them so you use the exact right amount.

** Any brand is fine, but be sure the cereal you use is fresh. Stale cereal will make for stale-tasting Rice Crispy Treats. To make a half-batch of Rice Crispy Treats, simply divide all ingredients in half and use an 8×8-inch baking pan.

That's largely due to the supply chain crisis affecting the food industry as a whole, Market Realist shares. But the way it's affecting Rice Krispies specifically has to do with the supply of barley malt extract, one of the main ingredients in the cereal.

Why are Rice Krispies Treats good for you? ›

The treats are low in fat and protein yet high in carbs, meaning they are easy to digest and are unlikely to cause GI distress. They can provide the body's muscles with the easily accessible carbohydrate they need to perform at a high level.

Can I leave homemade rice crispy treats out overnight? ›

Store the treats at room temperature for up to 3 days.

Store the container on the counter, in a cupboard, or anywhere that will stay room temperature. Room temperature can fall anywhere between 64 to 73 °F (18 to 23 °C). After 3 days, you should throw away the old rice crispy treats and just whip up a new batch!

What is a substitute for marshmallows in Rice Krispies? ›

The substitute breaks down like this: combine an inverted sugar (like syrup or honey) with a nut or seed butter to create a sweet adhesive for your Rice Krispy treats. Not only does this sticky mix work as a proper swap for marshmallows, but it also brings its own unique flavor to your crunchy bars.

Do homemade rice crispy treats go bad? ›

Unlike perishable food items, Rice Krispies treats do not go bad. They can be stored for long periods of time without becoming unsafe to eat. However, as previously mentioned, they may become stale or lose some of their flavor over time.

What to do if my Rice Krispie treats is too dry? ›

If the marshmallows cook too long, the texture of the sugar changes and your treats will turn out hard and dry. Cooking them in the microwave allows you to control the temperature better and cooks it at a low heat. Another tip for keeping your crispy rice treats soft and chewy is to use fresh bags of mini marshmallows.

How to keep melted marshmallows from getting hard? ›

To avoid this, it's important to melt them slowly over a low heat. Use a larger pan than you think you'll need, as the marshmallows will expand as they warm through.

How do you cut Rice Krispie treats without sticking? ›

To make cutting the treats a breeze, spray a knife or cookie cutter with non-stick cooking spray beforehand. This will prevent the marshmallow from sticking to the knife. If you have fun cookie cutter shapes, this is a great non-cookie use for them.

Why are my Rice Krispie squares so sticky? ›

Melting marshmallows heats the gelatin within, causing it to act as a sticky binder that holds the Rice Krispies together once cooled. Gently pressing the mixture into the pan, rather than compacting it firmly, ensures the treats remain airy, light, and crisp.
