There are so many things to love about this super easy rice krispie treat recipe, but here are just a few things:

• It’s super family/kid friendly

Ingredients

Rice Krispie cereal: You can use the name brand cereal or any generic brand of rice cereal that you want. In my experience, they all snap, crackle, and pop equally!

Marshmallows: The stickiness of the marshmallows is what holds the rice krispies in tact and gives them their sweet flavor. I like to use mini marshmallows, but you can use the regular or large marshmallows if desired.

Butter: Adding butter to your marshmallows not only gives more flavor, but keeps the melted marshmallows from becoming too sticky. Butter is key for making gooey rice krispie treats.

Pure vanilla extract: Adding vanilla to your melted marshmallow mix gives an incredible flavor to your rice krispie treats!

Salt: A pinch of salt helps bring out the flavors of the sweet elements.

M&Ms: You can’t make gooey M&M rice krispie treats without chocolate M&M candies! Chocolate and marshmallow is an incredible combination, and the candies add a fun pop of color! This recipe uses regular chocolate m&ms, but you could also use mini m&ms too.

How To Make Homemade Rice Krispie Treats

Before you get started, prepare a 9” x 13” glass pan by lightly spraying it with cooking spray. If desired, you can line the pan with parchment paper before spraying it.

The first step in making these M&M rice krispie treats is to combine marshmallows and butter. In a large microwave-safe bowl, add the marshmallows and butter. The marshmallows will expand quite a bit when you heat them so be sure to use a large bowl.

Microwave them for 2-3 minutes total in 1-minute increments. Keep an eye on it in the microwave to make sure the marshmallows don't overflow. Once the marshmallows and butter are completely melted, remove the bowl from the microwave.

Be sure to have the rest of the ingredients ready when you take the marshmallow mixture out of the microwave. You’ll need to add them immediately before it cools down.

Promptly add the vanilla and pinch of salt to the melted marshmallow mixture and use a spatula to combine. Then, add the rice cereal and mix until fully combined. Lastly, add in the chocolate M&M candies and mix.

Use a rubber spatula to transfer the rice krispie mixture into the pan and lightly press it out to fill the pan. Continue to press the mixture until the whole pan is covered and the rice krispie treats have an even thickness throughout. Keep in mind that the more you press them down, the more dense your rice krispie treats will be.

Serve & Store

Finally, allow your M&M rice krispie treats to set up. I like to leave them on the counter covered with tinfoil for an hour or so. You can also put them in the refrigerator to firm up faster if you’re feeling impatient. 

Once they are set up, slice them into squares and enjoy! If you want to save some for later, wrap them in parchment paper and keep them in the freezer in a sealed bag or container.

Recipe Tips & Tricks

Use salted butter: I like to use salted butter when making most sweet treats to add more flavor. This is definitely the case for homemade rice krispie treats as well.

Prep the ingredients ahead of time: Have all your ingredients ready when you begin microwaving your marshmallows and butter. The melted ingredients start to solidify quickly, so you need to mix in the dry ingredients right away.

Use a 9x13 inch pan: This will give the rice krispie treats a decent thickness and also make enough for a crowd.

Rice Krispie Treat Add-Ins

One of the best things about these gooey M&M rice krispie treats is the added candy. I love making rice krispie treats with M&Ms, but here are some other add-ins you might like:
