Mix yeast, 2 tablespoons of sugar and 50 ml milk until smooth. Leave in a warm place for about 10 minutes. Mix 375 g flour, salt and 50 g sugar in a bowl. Add yeast dough, remaining milk, egg and 50 g softened butter.
Knead everything with the dough hooks of the hand mixer for about 4 minutes to a smooth dough. Leave to rise in a warm place for approx. 30 minutes. Mix 50 g flour, grated coconut, vanillin sugar and baking powder.
Add 100 g butter in flakes and briefly work everything into crumbles with the dough hooks. Keep cold. Knead the yeast dough again. Form dough into a roll and divide into 8-10 equal pieces.
Shape dough portions into oval talers (approx. 8 cm Ø) with lightly floured hands. Spread on two baking trays lined with baking paper. Spread jam on top. Sprinkle the coconut crumbles over it.
Let it go again for about 5 minutes. Bake in the preheated oven (electric cooker: 175 °C / convection oven: 150 °C / gas: level 2) for approx. 20 minutes until golden brown. Remove and let cool on a cake rack.
Semi-stiff whipped cream tastes good with it.
