Prepare the yeast by dissolving it in a little lukewarm milk with a pinch of sugar. Let it sit for 10 minutes until foamy.
Crumble the butter into the flour, then add the proofed yeast, the remaining milk, sugar, and egg yolks. Knead the dough until it is smooth and homogenous.
Cover the dough and place it in a warm place for 1 hour to rise.
Meanwhile, prepare the filling: mix the ground walnuts with the powdered sugar, vanilla sugar, and enough milk to create a spreadable paste.
Roll out the risen dough into a thin rectangle and spread the walnut filling evenly over it.
Roll up the dough tightly, then place it on a baking sheet lined with parchment paper. Brush the top with beaten egg.
Bake in a preheated oven at 350°F (180°C) for 35-40 minutes, or until golden brown.
