Søsterkage: Christmas-Spiced Raisin and Orange Loaf Cake

Christmas is Coming!

Thanksgiving is behind us, temperatures are dropping, and twinkling lights and fir trees are beginning to appear — that can only mean one thing: Christmas is on its way. We love this season for many reasons: time with family, cozy nights by the fire, and small comforts that feel extra special in winter. A warm drink, a slice of cake, or a simple wreath can lift the spirits when it’s cold outside. Those little touches are what make the holidays so charming.

Today’s Recipe: Delicious and Festive

Today’s recipe is deeply rooted in family and local tradition: søsterkage, which translates to “sister cake.” It originates in Sønderjylland, a Danish region bordering Germany, where the local dialect even calls it søstekaach. The name is lovely — especially for a sister-run blog — and the cake itself is a regional specialty you won’t see everywhere online. This yeasted, spiced loaf with raisins and candied orange peel delivers classic festive flavors and comforting texture perfect for holiday gatherings.

Yeast in a Cake?

It might sound unusual to use yeast in a cake, but it gives søsterkage a lovely, slightly springy texture — think of a pound cake that’s a bit more structured and less crumbly. The loaf holds together nicely and has a denser, bread-like crumb compared with typical butter cakes. The flavors are similar to a fruitcake but more restrained: fewer dried fruits and nuts, moderate sweetness, and warm spices that pair beautifully with a thicker icing, jam, or simply a smear of butter on a slice.

Ingredients

This cake uses common baking staples: yeast, milk, eggs, sugar, butter, salt, and flour. The festive notes come from vanilla, lemon zest, candied orange peel (or Italian mixed peel), raisins, cardamom, and cinnamon. Stick with the basic ingredients for reliable results, although any milk variety will work. The flavor additions are flexible — try almond extract and dried cherries, or add walnuts and pistachios for extra texture if you like.

How to Make Søsterkage

We tested different methods and settled on the following process for the best texture and flavor. Warm the milk until it is “finger warm” (warm to the touch but not hot), then stir in the yeast with a small amount of sugar and let it activate until it froths. Melt the butter, cool it to finger-warm, and combine it with the milk and yeast. Whisk the eggs and brown sugar until pale and ribboning, then add lemon zest and vanilla.

Combine flour, salt, cinnamon, and cardamom in a bowl. Add half the liquid mixture to the egg mixture, whisk, then add half the dry ingredients. Alternate the remaining wet and dry ingredients, mixing just until combined. Toss the raisins and candied peel with a tablespoon of flour so they don’t sink, then fold them into the batter with a spatula.

Grease a medium loaf tin and line it with parchment. Pour in the batter, cover, and let it rise for 45–60 minutes — it should puff slightly but not reach the top of the tin. Preheat the oven toward the end of the rising time (about 190°C / 375°F). Remove the cover and bake 30–40 minutes until the top is well browned and a skewer comes out clean. Cool briefly in the tin, then transfer to a wire rack to cool completely before slicing.
