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.
Rainbow Rice Krispie Treats Recipe
Rainbow Rice Krispie Treats
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 1/2 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

These are so fun! Pinning for sure! 🙂
these are amazing and I know 2 little kids who would LOVE to eat the rainbow!
So colorful! Great for St. Patrick’s Day and summer!
The rice krispie treats are really cute. They would have been so perfect for a themed birthday party I just did for my daughter
I love your treats! So fun! Thanks for linking up with me for Friday Favorites. I’m featuring you this week!
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!
An also How many bags of mini Marshmallows??
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.
These will be beautiful for Pride celebrations. Thank you so much!
Yes! So perfect! Have fun!
Hi! Which brand of puffed rice do you recommend?
I use Millville from Aldi
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!
Great! I made them today for my boys.
Came out pretty.
