Burger King is no stranger to breakfast cereal based shakes. While having already released Froot Loops and Lucky Charms shakes in the past, the Cinnamon Toast Crunch shake is next on the docket.  Featuring vanilla soft serve, Cinnamon Toast Crunch cereal pieces, Sweet Cinnamon flavored syrup, and a whipped cream topping the Cinnamon Toast Crunch shake makes for one sweet treat. A standard sized shake packs 113 grams of sugar and 780 calories.
