Melt butter and marshmallows -add food coloring.

Take off heat and add Rice Krispie cereal {I use GF}. Spread this color in a glass 9×13 buttered pan.

Repeat this process with all the colors of the rainbow!

Keep on layering! I actually just wet my {clean} hands with water and spread…so easy that way.

Hey you! 😉

The top layer is not colored, but I did add some rainbow sprinkles for a “preview” of all the fun to come when you cut in! Warning: this dessert attracts children {he,he}

How adorable are these!? Ohhhh….I don’t know what child wouldn’t smile 🙂

Off to school!
