My sister and her family started making single serving Rice Krispie treats so they wouldn’t have a whole pan of dessert sitting around tempting everyone all week. I thought it was such a great idea, and now this little microwave version has become one of our favorite late-night treats after the kids are in bed.
And when you do need enough to share, our classic gooey Rice Krispie treats are the way to go. Or go all out with our brown butter dulce de leche Rice Krispie treats.
Why You’ll Love This Single Serving Rice Krispie Treat
- No whole pan of leftovers. It’s perfectly portioned for one sweet craving.
- Almost no cleanup. Mix it and eat it right from the mug.
- So gooey! Enjoy it warm and extra gooey or let it cool for that classic chewy texture.
- Easy to customize. Add chocolate chips, M&M’s, peanut butter or your favorite cereal.
Ingredients You’ll Need
Here’s everything you’ll need:
- Butter: Adds richness and keeps the melted marshmallows smooth. Salted or unsalted butter will work.
- Marshmallows: Mini marshmallows melt fastest, but regular marshmallows work too. For the smoothest, gooiest results, use fresh marshmallows.
- Crispy rice cereal: Rice Krispies give you the classic crunch, but other crispy rice cereals work too.

How to Make a Rice Krispie Treat in the Microwave
Grab a microwave-safe mug and you’re ready to go!
- Melt the butter and marshmallows. Add them to a microwave-safe mug and microwave until the marshmallows puff and soften.
- Stir until smooth. Stir the melted butter and marshmallows together until completely combined.
- Add the cereal. Quickly fold in the Rice Krispies while the marshmallow mixture is still warm and gooey.
- Enjoy! Eat it warm and extra gooey, or let it sit for a few minutes if you prefer a firmer Rice Krispie treat.
Tips for the Best Rice Krispie Treat for One
- Use fresh marshmallows. Older marshmallows don’t melt as smoothly.
- Don’t overheat them. Microwave just until the marshmallows are puffed and soft, then stir.
- Work quickly. Stir in the cereal while the marshmallow mixture is still warm.
- Use a microwave-safe mug with room to spare. Marshmallows expand dramatically as they heat.
- Grease your spoon if needed. A little nonstick spray or butter makes the sticky mixture much easier to stir.
- Eat it warm for maximum gooeyness. Let it cool for a few minutes if you want it to hold together more like a traditional bar.
Rice Krispie Treat Variations
The classic version is delicious, but it’s also fun to change things up! Try adding:
- Mini M&M’s
- Butterscotch chips
- Cinnamon chips
- Sprinkles
- Freeze-dried strawberries
- A pinch of cinnamon
- A pinch of flaky salt
Peanut Butter: Stir a spoonful of peanut butter into the melted marshmallow mixture.
Chocolate: Add mini chocolate chips after stirring in the cereal.
S’mores: Use Golden Grahams in place of some of the crispy rice cereal and add mini chocolate chips.
Can I Use a Different Cereal?
No Rice Krispies? No problem! Several other cereals work great in this single serving treat:
- Cheerios (any flavor)
- Chex (any flavor)
- Cocoa or Fruity Pebbles
- Crispix
- Honey Bunches of Oats
- Golden Grahams (add some chocolate chips and thank me later!)
- Another flavor of Rice Krispies (the cinnamon ones are so good!)
Rice Krispie Treat for One FAQs
Yes! Regular marshmallows work just fine, though they may take slightly longer to melt.
The marshmallows were most likely overheated. Microwave them just until they’re soft and puffy, then stir until smooth.
Yes. You can substitute coconut oil or your favorite dairy-free butter.
Yes, but you’ll need to use a crispy rice cereal specifically labeled gluten-free. Standard Kellogg’s Rice Krispies contain malt flavoring, so they aren’t considered gluten-free.
It’s buttery, gooey, crunchy and sweet! This Rice Krispie treat for one is exactly what you need for that late night craving! Now grab a mug, hide from the kids and enjoy every gooey bite! 😉 And if you make one, tag us on social media so we can see!
