Warm milk in a pot lukewarm. Dissolve yeast in it. Put flour and sugar in a mixing bowl and make a depression in the middle. Pour yeast milk into the flour bowl and mix with some flour.
Cover the pre-dough and let it rise in a warm place for about 15 minutes. Melt the fat, add the egg and salt to the yeast pre-dough and work into a smooth dough. Let it rise for another 15 minutes.
Divide the dough into 12 equally sized pieces. Shape 6 pieces into rabbit bellies. From the remaining pieces of dough form two ears, head and rabbit feet. Brush formed dough with water. Put together as a bunny on a floured baking tray.
Let it go for another 15 minutes. Decorate with pine nuts and peppercorns. Brush with whisked egg yolk. Bake in the preheated oven (electric: 200 °C/ gas: level 3) for about 20 minutes.
Tastes best when fresh.
