Rainbow Rice Krispie Treats

If you're looking for a fun but simple treat for St Patrick's Day, look no further.  These Rainbow Rice Krispie Treats require absolutely no baking, take less than 30 minutes to make, and turn out super cute.  The kids loved them, and I did too! Rainbows make everything so pretty!

I like to use gel food coloring because it's vibrant and a little goes a long way.  This Wilton Gel Food Coloring set has all the colors you need and then some.

Ingredients

  • 12 tablespoons butter divided
  • 9 cups mini marshmallows divided
  • 12 cups puffed rice cereal
  • Food coloring in rainbow colors

Instructions

  • Butter the inside of a 9"x13" baking dish.
  • Place 2 tablespoons of butter and 1 ½ cups mini marshmallows in a medium mixing bowl.
  • Microwave on high for 1.5-2 minutes, until butter is melted and marshmallows are soft.
  • Add your first food color (I used the traditional rainbow order: red, orange, yellow, green, blue, purple) and whisk together quickly.
  • Fold in 2 cups rice cereal.
  • Spread mixture into the bottom of your prepared baking dish, using a greased spatula to spread. I also used a piece of wax paper to help spread the layers flat without a sticky mess.
  • Repeat steps 2-5 for the remaining colors of the rainbow.
  • When all the layers are prepared, allow to cool. Then cut into squares for serving

        Depends on the type of food coloring. Just add until it reaches the desired level of color.

    Do you mean 12 cups of mini marshmallows? Or less than 2 cups each time? The math doesn't add up. Thanks

      I'm so sorry! Thanks for pointing that out. It should 1 1/2 cups each time, to make 9 cups total! I fixed the recipe now.

    I made these today as a tester to use at my wedding sweety table next august and they look amazing! I ve left them in the fridge for about 4 hours but they are still abit sticky, I m worried about cutting them incase they fall apart. Are they suppose to remain sticky or go abit harder? Not sure if I messed up somehow!

      I'm glad they turned out pretty for you! As far as texture, they'll be a bit sticky because of the marshmallow, but they should hold together. I cut mine up and transferred them straight to a plastic baggy and none of them broke apart at all. Let me know how it goes, and if there's issues, I'll be happy to troubleshoot with you 🙂

    Hi, I am planning to make this recipe for a birthday party next week.
    Can you tell how many boxes of cereal did you use for 12 cups?
    Thank you in advance!

        June 21, 2017 at 9:12 am

        You'll need 2 bags of marshmallows, too. There's about 6 cups in a normal sized bag.

      I remember it being a little over 1 box, so definitely grab 2.

    Hi,

    Can you all tell me which brand of cereal you use? I can't use Rice Krispies because they have malt in them.

    Thank you.

      Hi Lacy! I actually didn't know that! I just went and looked at the box I have in my pantry. It's Aldi-brand, and it doesn't have any malt in it. So if you have one near you, maybe check there! We love Aldi! Their food is high quality, and I can always find stuff without sketchy ingredients there!

    Just made these and they were great! The only thing I had to adjust was the microwaving time. My microwave's sweet spot was 35 seconds for each bowl. Thank you!

    I just made these, but have yet to cut and taste. I loved the picture so much!! I was using fluff so was guessing on measurements, but would love to know the measurements of fluff for the future? Thanks!!

    How long will these keep? I’m assuming an airtight container at room temperature for storing them?!

      Treats will stay crispy and fresh, if stored in an airtight container or zip-top bag at room temperature, for up to a week if you use salted butter.
