I love it when a few simple ingredients can come together to create something truly delicious and I think this rice krispie treats recipe is one of those magical ingredient combinations. It’s literally four simple ingredients but together they become a new magical thing that is simultaneously melt-in-your-mouth, soft and chewy, but also light and crispy. They’re just *mwuah* perfection. I like to make my rice krispie treats a little extra soft so that sweet marshmallow melts away to the crispy rice cereal within. You won’t be cutting the roof of your mouth on these babies! Just soft, gooey, marshmallowy goodness!

Ingredients for Rice Krispie Treats

The best thing about rice krispie treats is that you only need FOUR simple ingredients. Here’s what you’ll need to make them:

  • Butter: Salted butter helps soften the marshmallows to keep them gooey and it gives these rice krispie treats that rich, melt-in-your-mouth flavor.
  • Marshmallows: Marshmallows are the sweet, soft, and gooey glue that holds the crispy rice cereal together in a sliceable bar. We use mini-marshmallows because they’re easier to measure and melt more evenly than large marshmallows.
  • Vanilla Extract: A little vanilla gives the rice krispie treats a nice creamy flavor.
  • Rice Krispies Cereal: This delicate, crispy, air-filled cereal gives these bars their classic crunchy texture. You can use generic crispy rice cereal to save some extra dollars, too. Or, experiment with different types of cereals like corn flakes, Cheerios, or even corn puffs.

What Else Can You Add?

Add-ins are my favorite part of any recipe. And with something as simple as rice krispie treats, there is so much room for customization! Here are some fun things to add to make new flavors:

  • Almond extract and rainbow sprinkles for birthday cake-flavored treats
  • Replace some of the rice cereal with golden graham cereal and add chocolate chips and more mini-marshmallows (stir in with the cereal so they don’t melt) for smores-flavored treats
  • Stir some peanut butter into the melted marshmallows and drizzle chocolate over top
  • Use cocoa pebbles in place of plain rice krispie cereal and stir cocoa powder into the melted marshmallows
  • Stir in crushed Oreo cookies for a “cookies and cream” treat
  • Add peppermint extract to the melted marshmallows and stir in white chocolate chips with the cereal for a Christmas-flavored treat

How to Keep Rice Krispie Treats Soft

There’s nothing worse than a rock-hard rice krispie treat. To make sure your rice krispie treats are pillowy soft and delicious, follow these tips:

  • Use plenty of marshmallows (if you follow the recipe below you should have no problem). Marshmallows are what keep the bars soft and chewy.
  • Use fresh marshmallows. If they’re kind of dry or stale, that will affect how soft your rice krispie treats turn out.
  • Don’t overcook the marshmallows and butter. Sugars become more hard the longer they cook. So to keep your treats soft, make sure to only cook the butter and marshmallow mixture just until the marshmallows have melted, and not longer.

How to Store Rice Krispie Treats

Rice krispie treats can be kept at room temperature for a couple of days, or in the refrigerator for about five days. OR, if you’re like me and want to make them last even longer, you can freeze them in an air-tight container for up to three months. I just take one out at a time and thaw at room temperature for 10-15 minutes before going to town. :)

Melting butter in a pot

Add 6 Tbsp of salted butter to a pot and melt over medium heat.

Once the butter is melted, add 6 cups of mini marshmallows (or one 10oz. package). Continue to stir and cook over medium heat.

Melted marshmallows and butter in the pot

When the marshmallows are fully melted and incorporated into the butter, remove the pot from the heat. Stir in ½ tsp vanilla extract.

Make sure to stir until all of the cereal is well coated in the melted marshmallow mixture.

Rice krispie treats in the dish

Line an 8×8 dish with waxed paper or foil coated lightly with oil (I put a little oil on a paper towel and wipe the inside). Press the rice krispie mixture into the dish using a lightly oiled spatula. Avoid packing it down too firmly. Allow the treats to cool at room temperature or in the refrigerator until firm, then slice them into nine pieces.

Stacked rice krispie treats

Store the rice krispie treats at room temperature for about two days, in the refrigerator for five days, or in the freezer for longer storage.

  1. I don’t know WHEN you calculated your costs for items in your rice krispie treats, but they really need an update. Have you been to the supermarket lately? You’re recipe is fine, but your costs gave me a good laugh

    1. With a library of over 1500 recipes and grocery prices that fluctuate on a daily basis, unfortunately it’s impossible for our small team to keep the prices on all recipes current. The price breakdowns can still be useful when you look at which ingredients account for a majority of the total cost, or which ingredients provide a lot of volume without adding a lot to the cost. You can use this as a guide to help make your purchasing decisions when shopping for the recipe or making ingredient substitutions!

  2. This is my go-to recipe to use to make a childhood classic. I use vanilla bean paste and they turn out great every time!
