What You'll Need

This recipe comes together in no time, but let's quickly chat about some of the key ingredients and tools you'll need.

Ingredients

Unsalted butter - I always recommend baking with unsalted butter, not salted. That way, you have more control over the total amount of salt in the recipe.
Mini marshmallows - Mini is key here! If you use the big ol' marshmallows, it'll take a lot longer for them to melt, and they might burn on the bottom of the pan.
Rice Krispies - I always use Rice Krispies when making this recipe, but any kind of crispy rice cereal will work.
Graham crackers - We'll crumble up a few graham crackers to sprinkle on top of the rice krispie treats.
Milk chocolate - To mimic that classic s'mores flavor, I used Hershey's chocolate for this recipe, but feel free to use whatever chocolate you like. Semisweet or dark chocolate would also work here.

Equipment

Large pot - This recipe calls for a lot of marshmallows and cereal, so it's important to use a large pot. I like to use my Le Creuset dutch oven because it's so easy to clean.
Heatproof spatula - To keep the marshmallows from sticking to the bottom of the pot, you'll want to stir them constantly with a heatproof spatula. I personally like to use silicone spatulas since they're so flexible and durable.
9 x 13-inch pan - Using a 9 x 13-inch pan, this recipe yields 12 large squares, but feel free to cut them into whatever size you'd like.

Tips to Make This Recipe

Want to know the secret to making perfect rice krispie treats? Here are some of my best tips that I've learned over the years:

After pouring in the Rice Krispies, be sure to mix everything as quickly as possible. This step is crucial! Once you pour in the Rice Krispies, if you don't mix quickly enough, the melted marshmallows will start to solidify and won't distribute evenly throughout the mixture. Be sure to stir as quickly as possible and scrape the bottom of the pot well.
Press the mixture into the pan using a butter wrapper. If you've made rice krispie treats before, you know just how sticky they are. Luckily, your butter wrapper is here to save the day! Use it to press the mixture into the pan to avoid getting your hands sticky.
Let them cool for at least an hour before cutting into squares. If you try and cut these treats when they're still warm, you'll have a huge mess on your hands. It's best to let them cool for at least an hour before slicing.

Common Questions About This Recipe

You've got questions... I've got answers! If you have a question about this recipe that isn't answered below, feel free to leave it in the comments, and I'll jump in there to help you out.

How long does it take rice krispie treats to harden?

I recommend letting rice krispie treats cool in the pan for at least an hour before cutting them into squares.

How do you remove rice krispie treats from the pan?

Before pouring the mixture into the pan, be sure to generously spray it with nonstick cooking spray or grease it with butter. Then, when you're ready to remove the rice krispie treats from the pan, you can gently run a knife around the edge of the pan, and they should pop right out.

Should you refrigerate rice krispie treats?

Nope, you don't need to! You can let them cool and store them at room temperature. If you're in a rush, you can pop them in the fridge briefly to let them cool down, but it's not necessary.

How to Store & Freeze

To store: Cover and store leftover treats at room temperature for up to 3 days. When storing, place in layers between sheets of parchment or wax paper.

To freeze: While you can freeze these rice krispie treats, I don't recommend doing so because it can affect the texture. It's best to store these treats at room temperature and enjoy them within 3 days.
