The Original Rice Krispie Treat

Rice Krispies are such a nostalgic treat that is simple and super kid-friendly. My littles love to help me in the kitchen when I’m whipping up a batch. They also love to help me make peanut butter no-bake cookies, cake mix cookies, and no-bake cornflake cookies.

Rice krispie treats have to be the easiest dessert ever. When you’re in a pinch, they are one of the best no-bake treats to have in your back pocket. They come together quickly and are both kid and adult friendly. These rice krispy treats are the BEST and the secret is to reserve some of the mini marshmallows for the end.

This no-fail recipe is so simple and requires only 3 ingredients, although you can add nut butter for peanut butter rice krispie treats. I love to whip up a batch or two if I need a quick treat to bring to a get-together. The end result is a gooey, soft, and incredibly delicious treat that is loved by all. So easy and yummy!

  • Butter: This is a smooth and velvety texture. Melted unsalted butter doesn’t take long to do in a pan. Make sure it does not overheat or burn.
  • Mini marshmallows: These take a little longer to melt together. Marshmallows will be the glue and stick everything together.
  • Rice krispies cereal: The main ingredient! The cereal will help give it structure and a delicious snack to hold.

How to Make Rice Krispie Treats

Slowly cook, stir, and mix the ingredients together in a large pot. The marshmallows are ooey gooey, while the butter makes them silky smooth, and the rice krispies cereal gives it a base and structure form. Altogether this is a delicious and yummy treat!

  1. Prepare. Line a 9×13″ (or 9×9″ for thicker bars) baking dish with foil and butter. Set aside.
  2. Melt. Melt butter in a large saucepan over low heat. Add marshmallows and stir until they begin to melt.
  3. Mix. Once the marshmallows are almost melted, stir in the cereal and the extra marshmallows. Mix until completely coated in the marshmallow mixture.
  4. Press. Add mixture to a baking dish and push down with a spoon coated in butter or wax paper.
  5. Cool. Let cool completely before cutting. I like to cut mine with a plastic knife.

Key Tips for the Best Rice Krispies

Here are some ways to make sure that you have the very best rice krispie treats! Follow these tips and you will have an easy treat in no time. These are simple to make and come together quickly!

  • Butter your Pan. Because rice krispies are on the sticky side, they tend to stick to the pan. My favorite method to avoid this is to line my baking dish with aluminum, then butter the foil. I let the foil hang a little over the edges of the dish, so that I can easily grab it and remove them from the pan.
  • Use Low Heat. In order to get that gooey and fluffy texture that makes them so delicious, it’s important to melt the butter and marshmallows over low heat slowly. It may take a little longer, but it will result in a perfectly soft rice krispie treat. If you use too high of heat, you could end up with a hard texture.
  • Mix in Extra Marshmallows at the End. What takes them from ordinary to extraordinary is to reserve about 2-3 cups of the mini marshmallows to mix in at the very end. This makes them super gooey and delicious.
  • Let Cool Before Cutting. It’s important that you let them cool completely and harden a bit before cutting. If you try to cut them while the butter and marshmallows are still warm, they won’t hold their square shape. I usually let mine cool for about 30 minutes prior to cutting. You could even stick them in the fridge or freezer for a few minutes to speed up the process. I find it works best to cut the rice krispies into squares with a plastic knife.

Recipe FAQs

How many cups are in a box of cereal?

There are about 10 to 12 cups of cereal in a 12-ounce box of rice krispies. So to make this recipe, you’ll need about half a box of cereal. If doubling the recipe, you’ll use a full box. I love to have multiple boxes on hand so that I can easily whip them up whenever I’m in a pinch!

How do you keep rice krispie treats from getting soggy?

Most rice krispie treats don’t get soggy. They usually do become dry and hard if they are not stored properly. Cover the pan with the lid or plastic wrap tightly. When ready to serve, cut the treats into squares or shapes.

What happens if you put too much butter in rice krispie treats?

In all recipes especially baking it is all about balance and ratio. You will need the perfect balance or ratio between marshmallows and butter to make this treat perfect. Too much marshmallow and butter can make the treat too sticky, soggy, or wet whereas not enough can result in a dry and hard treat.

Storage and Freezing

To keep them fresh, store them in an airtight container or zip-top bag. You could even wrap the squares in foil or plastic wrap to eliminate sticking. They will keep at room temperature for 1-3 days.

To freeze, individually wrap the squares in foil and place them in a zip-top freezer bag. Store in the freezer for up to 2 months. Let thaw at room temp for about an hour or so before enjoying.
