Ingredients

  • Butter: This recipe calls for 1/2 tablespoon of salted butter. If you only have unsalted butter, add a pinch of salt during the melting process. Avoid using margarine for optimal taste.
  • Marshmallows: You’ll need either 1 cup of miniature marshmallows or 8 large ones. If you have leftovers, treat yourself to a luscious Mini S’mores Dip or a bowl of Ambrosia.
  • Crispy Rice Cereal: Use 1 cup of Kellogg’s Rice Krispies or any crispy rice cereal of your choice to achieve that classic crunch.

Recipe Variations

  • Chocolate Drizzle: Elevate your treat by drizzling warm, melted chocolate over the top. This adds a luxurious chocolatey layer that beautifully complements the crispy base.
  • Crunchy Nut Addition: For a textural contrast, mix in a handful of your favorite chopped nuts, such as almonds, pecans, or walnuts. This introduces a delightful nutty crunch that pairs perfectly with the soft marshmallows.
  • Fruity Twist: Stir in dried fruits like cranberries, raisins, or even chopped apricots for a burst of fruity flavor. This not only adds a chewy texture but also a natural sweetness and a pop of color.
  • Colorful Sprinkles: Add a playful touch with colorful sprinkles. This is perfect for special occasions or to simply brighten up your rice krispie treat, making it visually appealing and fun to eat.
  • Peanut Butter Swirl: Add a spoonful of peanut butter to the warm marshmallow mixture for a classic chocolate and peanut butter combo.

Making A Rice Krispie Treat

  1. Melting Marshmallows and Butter: In a microwave, heat the marshmallows and butter together for 30 seconds. This softens them for easy mixing.
  2. Mixing with Cereal: Once melted, stir in the rice cereal until it’s fully coated with the marshmallow mixture.
  3. Setting in Dish: Transfer this mixture into a buttered baking dish, spreading it evenly.

Creating a small batch Rice Krispie Treats is an easy and quick process, resulting in a delightful snack with minimal effort.

As the holiday season approaches, consider enhancing your individual Rice Krispie Treats with vibrant, festive candy toppings for a cheerful touch.

For an extra zesty flavor, try spreading a layer of lemon curd on top – it’s a deliciously tangy addition!

Expert Tips

For a perfect Rice Krispie Treat, follow these tips:

  • Prompt Removal of Marshmallows: As soon as the marshmallows are melted, take them out of the microwave. Overcooking can cause them to harden and thicken, affecting the texture of the treat.
  • Gentle Stirring: When combining the cereal with the marshmallows, stir lightly. Crispy rice cereal is fragile, and vigorous stirring might break the pieces, altering the treat’s texture.
  • Soft Pressing into the Pan: Press the mixture into your pan softly. The goal is to have a gooey, light treat, not one that’s overly firm and compact.

Frequently Asked Questions

How do I store Rice Krispies treats?

Store up to 3 days at room temperature in an airtight container.

Can I freeze Rice Krispies treats?

Yes! Place the treat in an airtight container and freeze for up to 6 weeks. Let stand at room temperature for 15 minutes before eating.

Can I double this recipe to make extra Rice Krispie Treats?

Absolutely, just double the ingredient amounts and use a larger dish.

  1. Thanks so much for this and all your recipes Joanie, my 6 and 8 yr old boys love making one for each of them and they get to be decorate them with any kind of sprinkle they want. We usually split each into two servings, so dessert two nights in a row, yay! Love these!

    1. I’m absolutely thrilled to hear that your boys are having a blast making their own Rice Krispie Treats! The idea to decorate them with their choice of sprinkles is just genius. It’s like a mini art project with a delicious outcome. Splitting each treat into two servings for dessert two nights in a row is a smart move! More to enjoy and it makes the fun last longer.

  2. Just made this tonight with unsalted butter. I really appreciate the nutrition facts as I recently had to go on a renal diet and it has helped me find some fun things to cook and still eat appropriately. Especially since I rarely enjoy leftovers. Thanks Joanie. ❤

  3. Simple, easy and super satisfying! I had the three simple ingredients on hand and am grinning from ear to ear with happiness over the satisfying taste and crunch! Boy have I missed Rice Krispie treats! I’ll be making again!

  4. This was great and simple too. My 7 year old grandson was over and was able to make this. (Yes, I oversaw his efforts.) I buy those variety packs of cereal and we used one of those bags. (32 grams/1.12 ounces) It was a scant cup but worked fine. We used Cocoa Puffs. Next we’ll try Golden Grahams and throw in some mini-chips.

  5. Add a tsp of peanut butter to the marshmallow mix while melting then add rice cereal-gives it some flavor. To get really crazy throw in a tblsp of mini chocolate chips after it’s all mixed but not too hot. Press into dish as usual.

  6. 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.

  7. 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.

    1. 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.
