Rainbows are seasonally appropriate for every season! They never go out of style.
Butter, marshmallow fluff, Rice Krispies. How could you possibly make this recipe more satisfying? Rainbows! Fruity Pebbles! I'm sure you'll all say, "Duh Ingo!" but I honestly never thought of this. Genius. I need to go to the store to stock up on cereal now. Brb.
When I was a kid, the closest I ever got to decorating my own cake was a cookie and a little tube of gel icing. I had plenty of fun with just that. Imagine how awesome it would have been if we had edible paper back then? I can't say I'm not a little jealous of kids these days.
