Lucky Charms Rice Krispies Treats

We love holidays around here, even the smallest ones! National Taco Day? Count me in! Earth Day? Right on!

It’s March 1st and that means St. Patrick’s Day is right around the corner. We don’t make a huge deal over it at home, but we still like to do some fun stuff with Jed and get in the spirit.

I wanted to bake something, but I wanted it to be simple and also not be so “in-your-face” St. Patrick’s Day. Rainbows and pots of gold provide endless activities you can do with your kids without the shamrocks and abundance of green (which is totally okay too)! We just opted for rainbows and lots of color this year!

Lucky Charms immediately came to mind and I thought “how easy and fun would it be to make rice krispies marshmallow treats but with Lucky Charms instead?” And that’s exactly what I did and am sharing on the blog for you today!

By far the easiest dessert I’ve ever made and ‘magically delicious’. Takes no more than 10 minutes to prepare and then the rest is letting it harden! It’s a great activity to do with your kids and provides gooey marshmallow-y breakfast cereal bars for a few days after if stored well! Yes, they are not the healthiest but that’s okay. Balance is great and providing an unexpected treat like this every now and then keeps life fun!
