For the yeast dough, put 750 g flour, 100 g sugar, 2 eggs, 100 g butter, 1 packet vanilla sugar and 1 pinch of salt in a large mixing bowl. Warm the milk lukewarm. Crumble the yeast into it, dissolve and pour into the bowl. Knead everything with the dough hooks of the mixer to a smooth dough. Cover and leave to rise in a warm place for about 45 minutes.
For the crumbles 200 g flour, 100 g sugar, 100 g butter, egg yolk, 1 packet vanilla sugar, 1 pinch of salt and 1 pinch cinnamon, first knead with the dough hooks of the mixer and then work into crumbles with your hands.
Knead the yeast dough on a well floured work surface with floured hands. Form dough into a roll (approx. 75 cm long), cut into 24 slices and shape into balls. Place balls on a baking tray (approx. 35 x 40 cm) lined with baking paper. Leave to rise in a warm place for another 30 minutes.
Mix the pudding and jam separately until smooth. Spread evenly in splodges on the pods. Sprinkle with crumbles. Bake in the preheated oven (electric cooker: 200 °C/circulating air: 180 °C/gas: see manufacturer) for approx. 25 minutes. Serve dusted with icing sugar lukewarm or cold.
