Microwaveable Rice Krispies Treats. Use this recipe to make Rice Cereal Treats in the microwave instead of on the stovetop.


Units Scale
  • 4 cups mini marshmallows or 40 Large Marshmallows (10 oz. bag)
  • 3 Tablespoons of Butter*
  • 6 cups of Rice Krispies (plus a little maybe?)
  • Non-stick butter spray
  • *can be omitted for a fat-free snack...but a little butter never hurt anyone, right?


  1. Pour the marshmallows into a microwave safe bowl - add 3 cut-up tablespoons of butter (be sure to mix the butter in so that marshmallows cover it up).
  2. Microwave for about 1 minute. Stir. Microwave for another minute. Stir again. If it's still not a very thin, melted consistency (like here in my marshmallow fondant), repeat at 30 second intervals until it's all melted and smooth.
  3. Stir in Rice Krispies until they're evenly coated. If they're too gooey, add alittle more cereal*. I like to use a silicone spatula to do's easy clean up!
  4. Next, spray a 9"X13" dish with non-stick butter spray or coat the pan with butter.
  5.'s a fun tip!  Also, take a spatula with a very flat turner and coat the underside with butter or butter spray - that way the cereal won't stick to it when you're spreading it out! Pour the cereal mixture into the dish, then take the back (flat) side of the spatula and spread the cereal and flatten it.  It works beautifully!
  6. At this point you can (if you must) let this 'set' for a few minutes and cool...OR you can eat warm, sticky, yummy Rice Krispie treats right away! All in all, this takes less than 10 minutes (more like 5), and if you wash your bowl immediately, the clean up is SUPER easy!


*I'm not sure if different brands of marshmallows melt differently or what, but sometimes the mixture seems gooier than other times. When this happens, I add an extra half a cup of cereal to stiffen up the mixture. If that's not enough, I do it again.
