Plum Cake peppered

First wash the plums, drain them, cut them in half and remove the core. Then sift the flour with mondamin, baking powder and sauce powder; Preheat the oven to 190 degrees and spread butter on a springform pan (26 cm) and sprinkle with breadcrumbs.

Separate the eggs and whip the egg whites with a pinch of salt, then set aside.

Beat the butter with the powdered sugar on the highest setting to a white-creamy mass, then gradually fold in the egg yolks. Stir in the sifted flour mixture alternately with the egg liqueur and finally fold in the egg whites (do not stir anymore, just "fold in" loosely).

Pour the dough into the prepared form and smooth it out, then "peck" the plums vertically into the dough and place the prepared cake in the preheated oven on the middle rail and bake there at a reduced temperature (approx. 170 degrees) for about 50 minutes .
