I also made Rice Krispies treats in the traditional Mardi Gras colors, purple, gold and green. I used Peeps for the marshmallow and pressed the layers into a loaf pan, a super quick and fun microwave confection that the kids thought were pretty neat, although the colors weren't as bright as I'd hoped. They tasted good, too, slightly different from the traditional recipe, but just as good. I'll make some other colors for Easter, I suspect, when we will also have our annual Peeps war, where the Peeps joust in the microwave with toothpick swords.
Happy Fat Tuesday! Enjoy it while you can! :)
