Finnish Blueberry Mini Cakes are the perfect dessert for anyone who loves light, fruity treats. These small, elegant cakes combine fluffy sponge with sweet whipped cream and tart blueberries, creating a classic Scandinavian flavor in every bite. These mini layered cakes are made with wild blueberries. They are ideal for parties, coffee breaks, or a simple weekend indulgence.
Choosing the Berries for Finnish Blueberry Mini Cakes
Wild blueberries are tiny but packed with flavor. Their deep, concentrated sweetness and natural tartness create a bold taste that shines in desserts. In these mini layered cakes, wild blueberries give each bite an intense blueberry flavor that pairs perfectly with creamy whipped layers.
If you want to use cultivated blueberries instead, remember that they are larger and milder. To compensate for the milder flavor, consider adding a touch of lemon juice to the soak and to the cake batter. Cultivated blueberries can give a visually striking presentation, even if the taste is slightly subtler than wild varieties.
Easy Ways to Bake and Garnish Finnish Blueberry Layered Cakes
You can easily adapt this recipe to a faster version. Baking it in a round cake pan creates a layered blueberry cake, saving time while keeping the classic flavor combination of sponge, cream, and berries. This version is perfect for when you need a larger dessert or want to skip assembling multiple mini cakes.
For presentation, top each mini layered cake with a few extra fresh blueberries. Then, add one of these simple garnishes: a small mint sprig, a few leaves of fresh lemon balm (sitruunamelissa), tiny edible flowers, or a few white chocolate shavings. These finishing touches not only enhance the vibrant colors but also make the cakes look elegant and inviting. Additionally, they pair beautifully with coffee or tea. Serve them the same day, as the whipped cream does not stay fresh long. Overall, these little details elevate the dessert and create a refined, café-style impression at home.

Instructions
Cake Base
- Grease a square or rectangular cake pan and coat with breadcrumbs. Preheat the oven to 175°C (350°F).
- Whisk the room-temperature eggs and sugar into a thick, pale foam.
- In a separate bowl, mix the flour, potato starch, baking powder, vanilla sugar, and lemon zest. Sift into the egg-sugar foam and fold gently to combine.
- Pour the batter into the prepared pan and bake for about 30 minutes.
- Test with a toothpick: if it comes out clean, the cake is done. Let cool completely.
- Cut the cooled cake into three even layers, then cut into small rectangles (about 6 × 4 cm), yielding 12 mini cakes.
Blueberry Soak
- Puree the blueberries and sugar into a smooth mixture. Use about 2 tsp to soak the bottom and middle cake layers.
Filling
- Whip the cream until soft peaks form, then gently fold in the lemon curd. Spread generously between the layers of each mini cake and scatter a few blueberries inside for a juicy bite.
Assembly

- Whip the cream and sugar for decoration, and transfer to a piping bag. Pipe neatly around the edges of each cake.
- Top each mini cake with fresh blueberries.
Glaze
- Make the glaze according to package instructions, or:
- Bring 2 dl water to a boil. Add 1 dl gelling sugar and let it boil briefly.
- Remove from heat and let cool slightly before spooning over the blueberries. ⚠️ If too warm, the glaze will melt the whipped cream.
- Chill the mini cakes before serving.
