3 egg yolks
3 tsp yeast
1 tsp sugar
pinch of salt
0.5 cup milk
1 tbsp vanilla sugar
3 egg whites
Bloom the yeast with the water and sugar. Mix in the egg yolks, flour, salt and knead into a smooth dough. Allow to rest for 30 minutes.
Butter a 9-by-13 glass dish.
Whip the butter with the sugar. In a food processor grind the walnuts, then add the butter and sugar mix and the egg whites.
Roll out the dough into 0.5-inch-thick. Spread with the walnut filling and roll up. Cut into 8-12 rolls. Place into the baking sheet. Allow to rise for about 30 minutes in a warm place, until airy and puffy.
Bake in a 350F oven until light brown. Pour the milk mixed with the vanilla sugar on top and set back in the oven for a few minutes, for the milk to absorb. Serve!
