Rice Krispie Treats were a favorite dessert of mine growing up. In fact, it was probably one of the first recipes my mother let me cook by myself. What could go wrong? Marshmallows, a little butter, Rice Krispies cereal - so easy to throw together.

What Are Rice Krispie Treats?

Rice Krispie treats are a dessert commonly made by binding Kellogg's Rice Krispies or another crisp rice cereal together with butter and marshmallows. They were first made in 1939 at the Kellogg company as a fundraiser.

I first posted this "Rice Krispies Treats Recipe For One" a few years ago when my kids were in college. I wanted to give them an easy recipe they could make in their dorm rooms.

The photos I took for that old post made me cringe; poor lighting, out of focus, and just plain old boring. Since this recipe for rice crispy treats is a total classic, I thought it was high time to update the photos and have a little fun with creating this single serving favorite again.

With the holidays right around the corner, you might want to consider adding colorful, festive candies as a topping to your rice crispy treats.

You can even spread a layer of lemon curd on top - talk about good!!!

Expert Tips

  • Once the marshmallows have melted, remove them from the microwave immediately. If they cook longer, the marshmallows will harden and thicken.
  • Don't overstir the cereal once it's added to the marshmallows. The crispy rice cereal is delicate and over-stirring can break the cereal pieces.
  • Press the mixture into the pan gently. You don't want a firm and compact rice krispie treat - instead, you want a gooey and light cereal treat.

Frequently Asked Questions

How do I store rice krispies treats?

What size dish is used in the photos?

For this rice krispie treats recipe, I use a 5-inch baking dish, for best results use a dish of similar size.

    I am so happy I found this recipe! I love Rice Krispie treats, but since I live alone, I never make them because I don’t want to eat the whole pan myself. Now that won’t be a problem. The only possible problem I can see is I might make this recipe to often 😊

    1. Hi Laura, I love this recipe so much and for the exact same reasons you do. It’s great for portion control and with Rice Krispies treats, I have absolutely no will power. This mini size is perfect for me 🙂 Thank you so much for letting me know like the recipe.

  2. Love the concept of cooking for one. Kids grown and out of house. Ex-wife moved on. Not found of fancy foods or left overs. Have freezed extra food but except for soups things get thrown out(my dogs love leftovers.). Thanks again.

      Thank you so much! I always had to make a big batch, for the “grandkids”. But Mimi always ended up eating most of them! This is sooooo perfect. I added a little bit of vanilla after I mixed it all up.
