Traditional Louisiana-style king cake has been a key ingredient of Mardi Gras celebrations for almost 150 years. The rich, moist Danish dough is glazed with cinnamon butter and loaded with sweet, sugary icing topped with carnival-colored sugars. Simply put, it's a dessert fit for a king. Hidden somewhere inside is a plastic baby (it's not edible so please be careful not to eat it) and whoever gets the slice with the baby gets to be king or queen for the day. Let the good times roll!
