This was delicious! The bottom crust is like a shortbread and the plums on top are sweet and creamy. This is a very nice summer dessert. I added about half the sugar called for at the end because the plums were already very sweet.
Very good! I added some cinnamon (because we in Croatia always put cinnamon with plums, apples and poppy seeds). I had some surplus of dough so I grated it over the top. Really very good, it will become my usual season cake. Thanks!
