Pour 500 g flour into a bowl and press a depression into it. Warm 100 ml milk lukewarm. Crumble yeast into the hollow, add 40 g sugar and milk and mix with some flour from the rim to a thick mash.
Cover the pre-dough and let it rise in a warm place for about 15 minutes.
Melt 150 g butter, add 100 ml milk and warm up lukewarm. Add 35 g sugar, milk mixture, eggs and salt to the pre-dough and knead to a smooth dough with the dough hooks of the hand mixer.
Cover the dough and let it rise again for about 30 minutes.
Knead 100 g butter, 25 g sugar, 75 caramel spread, 200 g flour and chopped nuts into crumbles with the dough hooks of the hand mixer.
Wash, stone and quarter the plums. Knead the dough again and divide into about 20 pieces. Roll out half of the dough pieces slightly oval on a floured work surface (approx. 5 x 10 cm).
Line a baking tray with baking paper and place dough pieces on top. Spread 1 tsp. caramel spread on each of the dough pieces. Place plum quarters on top and spread crumbles on top. In the preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: see
manufacturer) bake for approx. 25 minutes, remove from oven and allow to cool. Do the same with the second half of the dough. Whipped cream tastes good with it.
