Crumble the yeast into lukewarm milk, add a little sugar and flour, then mix. Let it stand in a warm place for 10 minutes, until it starts to foam. TIP: Use fresh yeast, as weak yeast will not raise a rich dough!
In a large bowl, mix together the flour, remaining sugar, salt, and vanilla sugar. This will be the dry base of the dough.
Add the egg, melted butter, and yeast mixture. Mix well, then add 100 g of mashed, cooled sweet potato and knead into a smooth, slightly soft dough.
Cover the dough and let it rise in a warm place for 45-60 minutes, or until doubled in size. Meanwhile, mix the remaining sweet potato with the walnuts – this will be the filling.
On a floured surface, roll out the risen dough into a rectangle. Spread the sweet potato and walnut mixture on top, leaving the edges empty.
Fold it in half lengthwise, so that one side slightly overlaps the other – this gives the classic Stollen shape. Press down gently.
Place the shaped dough on a baking sheet lined with parchment paper, cover, and let rest for 15 minutes. Meanwhile, preheat the oven to 350°F (180°C) (top and bottom heat).
Bake for 35-40 minutes, until the Stollen is nicely golden brown. If necessary, cover it towards the end to prevent the top from burning.
After cooling slightly, sift powdered sugar over it. TIP: If you brush it with melted butter, the sugar will stick better.
