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.
Green and purple are a good color match. Of course if you want to get into the full tertiary you could add some orange to round things out but I think this is looking pretty nice. Do you care? No? Either do I. Just eat it!
