For the brioches with poppy seeds, put flour in a bowl and mix with yeast, sugar and salt. Add milk, eggs and butter and knead everything into a smooth yeast dough.
Cover the dough and let it rise until it has doubled in volume. Then form the dough into a roll and divide it into 20 portions.
Form a large and a small ball from each portion. Press a small indentation in the large ball and place the small ball there.
Brush the brioches with the beaten egg yolk and sprinkle some poppy seeds on top. Bake in a preheated oven at 200 °C for about 20 minutes. Remove the brioches with poppy seeds and let them cool on a cooling rack.
Preparation Tip:
Enjoy the brioches with poppy seeds for example with lemon curd or powidl jam.
