A classical German cake in autumn is the plum cake. It is basically a must to eat it with whipped cream.
Mix all ingrediences (besides the plums...) and let it grow for about 30-40 minutes in a warm place, covered by a wet towel. Probably it won't grow really high, but that is normal.
Half the plums, take the stone away and wash them
Roll the dough onto a baking tray, and place the plums over it. Place them somewhat standing and overlapping.
Put it into the Oven in around 200 (C) degrees for 25-35 minutes, until the plums are getting soft and brown.
Take it out and sprinkle sugar over it. Depending on the sweetness of the plums, you need different amounts...
Serve it with whipped cream
