German Plum Cake (Pflaumenkuchen) vs Traditional Dorset Apple Cake

Both cakes lean on butter, sugar, egg and cinnamon, but they deploy them in opposite ways. The Pflaumenkuchen rubs cold butter quickly into flour for a thin shortcrust base, then crowds it with halved plums baked cut-side up under a dusting of sugar and cinnamon, so the fruit turns tender and juicy over a golden edge. The Dorset apple cake creams softened butter and sugar into a moist, springy crumb, folding diced tart apples and lemon zest through the batter and finishing with crunchy demerara on top. One is fruit-forward and sheet-baked; the other is a tender, cinnamon-spiced cake studded with apple.
