Nothing captures the perfume of a Finnish December kitchen quite like the first pan of joulutortut emerging from the oven. On dark afternoons when the world outside is hushed by snow, the buttery scent of pastry mingled with simmering prune jam is an announcement that Christmas is on its way. These pastries, variously called joulutorttu (“Christmas tart”) or tähtitorttu (“star tart”), are simple pinwheels of laminated dough with a gleaming jam filling and a snowfall of powdered sugar. Baked across Finland and, increasingly, anywhere Nordic holiday traditions are appreciated, their star shape recalls the Star of Bethlehem while the jam‑filled center offers a burst of concentrated fruit as comforting as a grandmother’s hug.
A Brief History From Half‑Moons to Stars
The origins of joulutortut are intertwined with centuries of European baking. According to food historian Tytti Nieminen, laminated pastries filled with sweet or savoury fillings were already being made in the 1700s. They were not yet tied to any particular season; round pies of flaky dough were simply part of the nobleman’s table. The idea of a Christmas tart travelled to Finland via the gentry, manor houses and rectories from neighbouring Sweden. Swedish cookbook author Cajsa Warg published a recipe for a layered butter pastry with jam in 1755, and her instructions spread widely across the Nordic countries; Finnish bakers could not easily adopt such recipes until ovens became more common in the 1800s.
By the 1820s people in Finland had begun baking pastries specifically for Christmas. Plum and apple‑filled tarts appeared on the dessert tables of wealthy households by century’s end. Early shapes were half‑moons or simple rounds; the star form familiar today first appeared in the seminal 1908 cookbook Kotiruoka. The shape, likely inspired by the Star of Bethlehem, quickly gained popularity and is now synonymous with joulutorttu. Traditionalists may fold the jam under the pastry points, while others spoon it on top; either way the gleaming “eye” of prune jam is essential.
For many Finns, baking joulutortut is as much about memory as it is about pastry. Baking courses, household journals and widely distributed cookbooks helped standardise Christmas recipes across Finland in the early 20th century. Today nearly every household enjoys them, whether made from scratch, assembled from frozen sheets at a work Christmas party, or purchased from a local bakery. A 2020 estimate by dough producer Myllyn Paras suggested that Finns eat about 18 Star Tarts per person each year, a statistic that hints at just how beloved these buttery stars are.
Traditions and Customs
In Finland, Star Tarts are baked throughout December and served with coffee or glögi, a spiced mulled wine. Families may dust the pastries generously with powdered sugar or keep them barely sweet; some argue over whether the jam should sit beneath the pastry points or on top. Historically, prune jam became the standard filling because dried plums, though imported, were less likely than berry or apple preserves to leak out during baking. Half‑moon tart forms could be cut with a drinking glass, while the star form requires a few quick knife cuts and nimble folding.
Like many Christmas foods, joulutortut have adapted to their era. During periods of austerity in the 1920s and 1930s, home bakers replaced butter with margarine or lard and stretched wheat flour with mashed potatoes. Fillings were reinvented with whatever was on hand, from dried fruit compotes to carrot custard during the war years. Today’s imaginative bakers continue this spirit, filling their pastries with apple‑cinnamon jam, apricot or lingonberry preserves, quark mixed with sugar, or even savoury ingredients like brie and beetroot. The Finnish Wikipedia notes that modern variations include candies such as Vihreä Kuula (green jelly sweets) and unusual savoury fillings ranging from beetroot salad to brie or even French fries. Social media recently sent vihreä kuula–tortut trending, and there are even reports of experimental tarts filled with liver pâté.
Ingredients, Substitutions and Modern Twists
Dough choices: Traditionally, Star Tarts or joulutortut are made from voitaikina or laminated puff pastry. In Finland you’ll find “voitaikina” (butter‑based), “lehtitaikina” (vegetable‑fat‑based) and “torttutaikina,” all sold in rectangles. To achieve the best flavour at home, choose a butter‑rich dough. This blog provides a scratch‑made dough inspired by the quark‑and‑butter pastry (rahkavoitaikina) used in many Finnish households. If quark is hard to find, ricotta or full‑fat cottage cheese makes an excellent substitute. For a time‑saver, high‑quality frozen puff pastry can stand in; look for one made with butter for better flavour.
Jam and filling: Thick prune jam is the classic; its density prevents it from running in the oven. Store‑bought baking jam is widely available and should be chilled before use to further reduce spread. If you cannot find prune jam, any thick fruit butter (apricot, apple‑cinnamon, fig, raspberry) will work; just avoid runny jams intended for spreading on toast. For a contemporary twist, try a spoonful of spiced cranberry sauce, mincemeat or even chocolate‑hazelnut spread. Savoury riffs are equally fun: dollops of goat cheese with lingonberry jam or caramelised onion jam with brie are surprisingly festive.
Spices and enhancements: A whisper of cardamom or grated orange zest kneaded into the dough nods to other Nordic Christmas breads. Dusting with powdered sugar is traditional and evokes freshly fallen snow, but you might sprinkle pearl sugar or drizzle with a simple glaze scented with orange blossom. Vegan versions can be made by substituting plant‑based butter and a thick coconut yogurt in place of quark, while gluten‑free bakers can experiment with a gluten‑free flour blend and xanthan gum (note that results may be less flaky).
Finnish Christmas Star Tarts Recipe
Below is a from‑scratch recipe formatted for WP Recipe Maker. It makes about 12 medium tarts. The dough uses quark (or ricotta) for richness and tenderness, and the filling is a good-quality, store‑bought prune jam. Measurements are given in both metric and US customary units. If you prefer to use frozen puff pastry, skip the dough section and proceed directly to cutting and shaping.
Christmas Star Tarts – A Festive Pinwheel of Butter and Jam
Ingredients
Method
- In a medium bowl, whisk together the flour, baking powder and salt. Add the cold butter cubes and quark. Using a pastry cutter or your fingertips, quickly work the fats into the flour until the mixture resembles coarse crumbs with some pea‑sized pieces of butter. Avoid warming the butter too much.
- Gather the dough into a rough ball. It will be soft and shaggy. Divide into two disks, wrap each tightly in plastic wrap and refrigerate for at least 1 hour (or up to overnight). Chilling allows the gluten to relax and the butter to firm.
- On a lightly floured surface, roll one disk into a rectangle about 8×16 inches (20×40 cm). Fold the bottom third up and the top third down, like folding a letter. Rotate the dough 90 degrees, roll out again and fold into thirds once more. Repeat this rolling and folding process 2–3 times to create layers. Wrap and chill for 30 minutes before shaping. Repeat with the second disk.
- Heat your oven to 435 °F (225 °C). Line two baking sheets with parchment paper.
- Working with one piece of dough at a time, roll to a sheet about 3 mm (⅛ inch) thick. Trim the edges to a neat rectangle. Cut into squares roughly 8–10 cm (3–4 inches) wide. If using frozen puff pastry, thaw according to package directions and cut similarly.
- To form the classic star, make four diagonal cuts from each corner of a square toward the centre, stopping about 1 cm (½ inch) from the middle. Place a teaspoon of chilled jam in the centre. Fold every other corner toward the centre to create a pinwheel, pressing lightly so they stick. Transfer to the prepared baking sheet. (Alternatively, fold the corners over the jam for a covered tart; this is a matter of taste)
- Brush the pastry points lightly with beaten egg for shine. Bake in the preheated oven for 12–15 minutes until puffed and deeply golden. The jam will bubble. Rotate the sheets halfway through if your oven has hot spots.
- Remove from the oven and let the tarts cool on the baking sheet for 5 minutes, then transfer to a wire rack. Dust generously with powdered sugar while still slightly warm, allowing it to melt and create a snow‑like finish.
- Joulutortut are best eaten fresh, but they will keep in an airtight container at room temperature for a day or two. Re‑crisp day‑old tarts in a 175 °C (350 °F) oven for a few minutes. Unbaked, shaped tarts can be frozen on a tray then stored in a bag; bake from frozen, adding a few minutes to the time.
Notes
Notes and Variations
- Quick version: Use high‑quality frozen puff pastry. Thaw, cut and shape as directed; fill with jam and bake until golden.
- Alternative fillings: Try apple‑cinnamon jam, apricot preserves, lingonberry‑quark, fig jam, lemon curd or chocolate‑hazelnut spread. Savoury variations can include brie and cranberry relish, goat cheese with cloudberry jam, or even caramelised onions and blue cheese. Ensure fillings are thick to prevent leakage.
- Vegan: Substitute plant‑based butter for dairy butter and coconut yogurt or thick oat-based yogurt for quark. Brush pastries with plant milk instead of egg.
- Gluten‑free: Replace the all‑purpose flour with a gluten‑free baking blend plus ½ teaspoon xanthan gum. Expect a slightly less flaky texture.
- Make it decorative: Sprinkle slivered almonds over the jam before baking, or drizzle cooled tarts with a glaze of powdered sugar mixed with a few drops of orange juice.
Serving Suggestions and Final Thoughts
A tray of warm joulutortut is more than a sweet treat; it is an edible symbol of Finnish hospitality. Serve the tarts with hot glögi (spiced berry punch), strong coffee or a mug of cocoa. In northern homes they often appear on the kahvipöytä (coffee table) alongside gingerbread cookies and slices of spiced rye bread. Their star shape makes them a charming addition to cookie platters and a thoughtful gift for neighbours. When you bake them, you join a tradition that stretches back to the 19th century, when plum‑filled pastries first graced Finnish Christmas tables. Whether you follow the classic path or experiment with quirky fillings, Finnish Christmas star tarts offer a taste of Nordic winter magic and a chance to slow down in the flickering candlelight.
