This beloved Nordic dessert pairs a soft, buttery shortbread-style crust with sweet-tart blueberries under a golden crumb topping. In Finland it is traditionally served warm with cold vanilla custard sauce for a beautiful hot-and-cold contrast.

Ingredients
For the base
- 2 cups (260 g) all-purpose flour
- 1/2 cup (100 g) granulated sugar
- 1 tsp baking powder
- 1/2 tsp fine sea salt
- 1/2 cup (115 g) cold unsalted butter, cubed
- 1 large egg, lightly beaten
- 1/2 cup (120 ml) whole milk
For the blueberry filling
- 4 cups (560 g) fresh or frozen blueberries
- 1/4 cup (50 g) granulated sugar
- 1 tbsp potato starch or cornstarch
- 1 tsp vanilla extract
For the crumb topping
- 1/2 cup (65 g) all-purpose flour
- 1/3 cup (65 g) granulated sugar
- 1/4 cup (55 g) cold unsalted butter, cubed
Directions
- Preheat the oven to 400°F (200°C) and lightly grease a 9×13-inch rectangular baking pan or line it with parchment paper.
- In a large bowl, whisk together the flour, sugar, baking powder, and salt for the base. Cut in the cold butter with your fingers or a pastry cutter until the mixture looks like coarse crumbs, then stir in the egg and milk to form a soft, sticky dough.
- Press the dough evenly into the prepared pan, pushing it about 1/4 inch up the sides. Bake for 10 minutes until just set and lightly golden at the edges.
- While the base bakes, gently toss the blueberries with the sugar, potato starch, and vanilla in a bowl. In a separate small bowl, rub the crumb topping ingredients together with your fingertips until large, pebbly clumps form.
- Scatter the blueberries evenly over the warm pre-baked crust and sprinkle the crumb topping generously over the fruit, letting some berries peek through.
- Return the pie to the oven and bake for 28 to 32 minutes, until the topping is deep golden and the blueberry juices bubble thickly around the edges.
- Cool the pie in the pan on a wire rack for at least 20 minutes so the filling can set, then serve warm or at room temperature with cold vanilla custard sauce or a scoop of vanilla ice cream.
- Leftovers keep loosely covered at room temperature for 1 day or refrigerated for up to 3 days; reheat gently before serving.
Cook’s Notes
- Wild Finnish bilberries are smaller and more intensely flavored than cultivated blueberries; if you can find them, use them straight from frozen without thawing for the most authentic flavor.
- Serve the pie slightly warm with traditional Finnish vanilla sauce, which is simply milk, sugar, cornstarch, and vanilla beaten into a thin, pourable custard.
- A squeeze of lemon juice (about 1 tsp) brightens the berry flavor if your blueberries taste very sweet or mild.
- For a yeasted version, replace baking powder with 1 packet active dry yeast, omit the egg, and use lukewarm milk; let the dough rise 45 minutes before pressing into the pan.
