This Polish Plum Cake is a delicious coffee cake made with a very simple batter, fresh plums, topped with crumble and icing. It’s made with Italian Prune Plums, sometimes called Empress plums, prune plums or Węgierki in Polish. These European plums are small, dense, and egg-shaped, with blue or purple skin and yellow, firm and juicy flesh. Their pits separate easily from the flesh. These plums are perfect for baking and are usually available at local markets in late summer, from the end of August to early October.
A 12-inch tart baking pan works best for this recipe, but a springform will do as well. Alternatively, you can use a 9-inch deep dish pie pan. In this case, the batter will be spread in a thicker layer and rise higher during baking. To make sure that the cake is baked through, adjust the baking time by adding about 10 more minutes to the original baking time and make the toothpick test before taking it out of the oven.

- Take cake out of the oven and let cool down completely. Prepare the icing by stirring confectioners’ sugar with boiling hot water until you get the desired consistency and the icing is creamy and shiny. Using a spoon, pour icing over cake. Let the icing set before serving.
