125 g butter
vanilla
flour (as needed to make a dough)
Filling:
150 g caramelized sugar
1 cup milk
150 g confectioner`s sugar
vanilla or 1/4 cup rum
150 g butter

Make a dough out of sour cream, butter, vanilla and flour. Knead a medium soft dough. Let rest for a half hour, then divide into 9 equal parts. Roll each part into round sheets the size of the baking pan. Bake the sheets one by one, after pricking them with a fork. In the meantime, caramelize 150 g sugar in a small pan. In another pan, place the milk, 150 g sugar, vanilla (or rum) and the butter. Add the caramelized sugar, mix and let come to a boil. Spread this mixture on 8 of the sheets. Break the 9th sheet into little pieces and sprinkle on the last sheet with cream on it. Serve this cake the following day after preparation.
