Sweet potato stollen

The German classic of the Christmas season has received a modern twist: cooked sweet potato mixed into the dough not only lends the loaf a beautiful amber hue but also ensures softness that lasts for days. Stollen was originally a heavy, dense festive bread symbolising the swaddled child, but in this version, the dough is lighter and the filling creamy and nutty. As it bakes, the scent of butter and yeast mingles with the sweetness of caramelising sweet potato, creating a true festive atmosphere.

Ingredients

Equipment Needed

  • Large mixing bowl: For comfortable kneading of the dough.
  • Sieve: For aerating the flour and dusting with icing sugar.
  • Rolling pin: To achieve even dough thickness.
  • Baking parchment: To prevent the sugary filling from burning onto the baking tray.

Instructions

1

Crumble the yeast into the lukewarm milk, add a tablespoon of sugar and flour. Mix and leave undisturbed for 10-15 minutes until a thick, cracked foam appears on top and it smells sour.

Tip: The yeast fungi feed on sugar and produce carbon dioxide (fermentation); this gas will later raise our dough.
2

In a bowl, mix the flour, remaining sugar, salt and vanilla sugar. Make a well in the centre.

Tip: Salt regulates yeast activity and enhances sweet flavours, but it shouldn't come into direct contact with concentrated yeast at the start.
3

Pour the activated yeast, egg, soft butter and 150 g of cooled, mashed sweet potato into the well. Knead the dough for 10 minutes until it separates from the side of the bowl and feels silky.

Tip: During kneading, flour proteins form a network (gluten structure) capable of trapping the bubbles produced. The sweet potato starch adds extra softness.
4

Cover the bowl with a clean tea towel and prove in a warm, draught-free place for about 60 minutes until the dough doubles in volume.

Tip: A warm environment speeds up the yeast's work. If you press it with your finger and the indentation remains, the dough has risen.
5

Mix the remaining 100 g of sweet potato with the roughly chopped walnuts. Roll out the risen dough into a finger-thick rectangle, spread with the filling, then fold the longer side over so the edges don't quite meet (stepped fold).

Tip: This shaping ensures the characteristic 'swaddled' shape and prevents the filling from leaking out during baking.
6

Rest the shaped dough on the baking tray for another 15 minutes, meanwhile preheat the oven to 180°C. Bake for 35-40 minutes until dark golden brown and it sounds hollow when tapped on the bottom.

Tip: The hollow sound indicates that the dough structure has set and excess water has evaporated.
7

Brush thoroughly with melted butter while still hot, then immediately sift thickly with icing sugar. Repeat the sugaring after cooling.

Tip: The sugar melts into the hot butter, forming an insulating layer that would (theoretically) keep the cake fresh for months.

Recipe FAQ

Why did the dough crack during baking?
This is natural and even desirable for Stollen, part of its rustic appearance. The steam forces its way out through the dense filling.
How long does it keep?
Wrapped well in a cool place, it remains delicious for 1-2 weeks; in fact, the flavours truly mature after a few days.
