The secret to the swirls is relatively simple. As Cake Journal demonstrated in a handy tutorial, the look is achieved by kneading together two or more complementary colors of fondant. Et voila! It yields an ultra-sophisticated cake, like this complex, marbleized glaze from Sydney bakery es.Z Cake Design.
Not only is the result Instagram-ready, the marbleized appearance makes slicing into these cakes look like a Sword and the Stone-style magic trick. And if it tastes as flawless as it looks, this trend could become a wedding-reception mainstay. We certainly wouldn't complain.
