In this article
Discover Raparperipiirakka, Finland’s much-loved rhubarb cake! Tart stalks of spring rhubarb meet a soft, buttery sponge to create a bake that is sweet and sharp in equal measure. It is the sort of thing Finns pull out of the oven on a bright May afternoon and serve, still faintly warm, with strong coffee. Simple to make and endlessly forgiving, it belongs on any spring table.
About Raparperipiirakka
The Finnish Raparperipiirakka, known in English simply as rhubarb cake, is a traditional favourite that many Finns count among their best-loved treats. The bake pairs the bracing freshness of rhubarb with a sweet, buttery batter. That characteristic tang is framed by a tender crumb which wins over children and adults alike. In Finland the cake is nearly always served with coffee or tea, and it is a fixture of the country’s famous coffee culture.
Ingredients (serves 1–2)
- 200 g rhubarb, cut into small pieces
- 150 g sugar
- 100 g butter, at room temperature
- 200 g plain flour
- 2 eggs
- 1 tsp baking powder
- 1 tsp vanilla sugar
Shopping for the ingredients
For Raparperipiirakka it really is worth using fresh ingredients to get the best possible flavour. Rhubarb appears mainly in spring and early summer, so that is the ideal window to buy it fresh from a market stall. Many supermarkets also sell it ready-washed and chopped, which saves time and simplifies the preparation. When choosing your stalks, look for firm, crisp specimens without brown patches or wilting leaves.
Preparing the dish
Before you start on the Raparperipiirakka, a little careful groundwork pays off. Begin by washing the rhubarb thoroughly and cutting it into small pieces. It is a good idea to toss the fruit with the sugar and leave it to stand for a few minutes before you use it. This draws out the excess liquid from the rhubarb and stops the finished cake from turning soggy.
Step-by-step instructions
- Preheat the oven to 180°C (conventional top and bottom heat).
- Beat the butter and sugar together in a bowl until the mixture is creamy.
- Add the eggs one at a time, stirring well after each addition.
- Combine the flour with the baking powder and vanilla sugar, then fold the mixture into the butter mixture a little at a time.
- Add the prepared rhubarb pieces and mix everything together well.
- Pour the batter into a greased baking tin and smooth the surface evenly.
- Bake in the preheated oven for around 40–45 minutes, until the top is golden brown.
- Let the cake cool briefly after baking before turning it out of the tin.
Gluten-free / lactose-free version
For anyone avoiding gluten or lactose, the Raparperipiirakka recipe adapts with very little effort. Use a gluten-free flour blend in place of ordinary wheat flour. To take the lactose out, reach for lactose-free butter or margarine, both of which give you much the same consistency. These small adjustments mean every sweet tooth can enjoy the cake without giving up its authentic character.
Tips for vegans and vegetarians
Vegans can make Raparperipiirakka just as easily by swapping the eggs for plant-based alternatives. A popular option is apple purée, or a mixture of water and chia seeds as a binder. Instead of butter, use vegan margarine or coconut oil to keep the batter at its best. These straightforward changes produce a delicious vegan version of the traditional recipe with no loss of flavour.
More tips and tricks
One of the best ways to deepen the aroma of a Raparperipiirakka is to add a spice or two. A pinch of cinnamon lends the batter extra warmth, while a hint of lemon zest sharpens the freshness of the rhubarb. Another useful trick is to dust the cake with icing sugar before serving, which gives it an appealing finish. To make sure it browns evenly, turn the tin once during baking.
Adapting the recipe to your taste
The great thing about this cake is how adaptable it is, leaving plenty of room for your own ideas. Try other fruit such as strawberries or blueberries alongside the rhubarb to create new flavour combinations — much as Finnish bakers do in a Mustikkapiirakka. If you would rather keep things classic and traditional, simply vary the amount of rhubarb to reach the level of tartness you want. That flexibility makes it easy to suit different palates.
Ingredient substitutions
If you find yourself short of an ingredient, there are plenty of alternatives to fall back on. Frozen rhubarb works in place of fresh, though you should let it drain properly first. For the sugar you can use alternative sweeteners such as honey or agave syrup, bearing in mind that these will change the moisture content of the batter. Apples make another fine substitute, as they do in an Omenapiirakka. Swaps like these let you experiment and discover new flavours.
Drink pairing ideas
Raparperipiirakka goes beautifully with a range of drinks that draw out the flavour of the cake. The classic choice is a cup of freshly brewed coffee, whose bitterness makes a lovely contrast to the sweetness of the bake. A fresh herbal tea such as mint or camomile is an equally refreshing companion. On warm days, a lightly sweetened iced tea is another good option that brings out the fruity notes of the rhubarb.
Serving and presentation ideas
To present the cake attractively, garnish it with fresh rhubarb batons or a scattering of berries. Dust it lightly with icing sugar just before serving for an appetising finish. A handsome serving platter, or portioning the cake into individual squares, also lifts the presentation. It not only makes an impression but is a lovely way to enjoy the dessert and set a relaxed mood — the same easy hospitality that surrounds a plate of Korvapuusti.
A bit of history
Raparperipiirakka has its roots deep in the Finnish countryside and has become a favourite dessert across the whole country over the years. Rhubarb itself reached Europe in the seventeenth century and quickly found a place in traditional cooking. In rural communities the cake was above all a way of using up the harvest and making the most of seasonal produce — a thrifty instinct that runs right through Finnish cuisine. That tradition has endured, and the cake remains a fixture at celebrations, family gatherings and coffee tables throughout Finland.
