For the buttercream, stir 150 ml milk, 75 g sugar and pudding powder until smooth. Bring 750 ml milk to the boil in a saucepan, stir in the pudding powder, bring to the boil while stirring and simmer for 1 minute. Put the pudding in a bowl, place foil directly on the surface and let it cool down at room temperature for about 4 hours. Let 500 g butter rest at room temperature for about 4 hours. For the yeast dough mix flour, salt and 125 g sugar in a large mixing bowl, add 100 g butter in flakes, bitter almond oil and eggs. Warm 250 ml milk lukewarm.
Crumble yeast into it and dissolve. Pour on the flour and knead with the dough hooks of the hand mixer to a smooth dough. Cover and leave to rise in a warm place for about 45 minutes. In the meantime melt 150 g butter in a pot. Add 200 g sugar, vanillin sugar and cream, bring to the boil while stirring. Remove from the heat, stir in flaked almonds and let cool. Knead yeast dough with floured hands, roll out in a greased fat pan of the oven (32 x 39 cm) and let it rise again in a warm place for about 20 minutes. Spread almond paste evenly on top. Let it rise again for about 15 minutes. Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for about 20 minutes. Take out, place on a grid and let it cool down. Quarter the yeast dough.
