Lavender Ombre Cake with Petal Icing

Like all great show-stopper bakes, this cake requires some time and commitment to get the sponge colours and layers just so, and to pipe the icing in a way that is neat and level. Of course, if you don’t have the patience for this simple ‘petal’ icing technique, then just spread your cake with the frosting, pile some blueberries on top and dust with icing sugar.
