Yield: 12
Ingredients: 250 g plain flour; 100 g sugar; 150 g butter (cold); 1 egg; 1 teaspoon baking powder; 1 packet vanilla sugar; a pinch of salt; 250 g blueberries (fresh or frozen); 60 g plain flour; 40 g sugar; 40 g butter

Sift the plain flour into a bowl, add the sugar, vanilla sugar, baking powder and a pinch of salt. Add the cold butter cut into cubes and work it into the dry mixture with your fingers. Add the egg and quickly work into a smooth dough. Wrap the dough in cling film and let it rest in the refrigerator for at least 30 minutes.

Wash the blueberries and dry them well. If you are using frozen ones, let them partially thaw and lightly coat them in a tablespoon of flour so they don't release too much juice.

Preheat the oven to 180 °C. Roll out the dough on baking paper and transfer it to a tray lined with paper. Spread the dough evenly into the corners. Arrange the blueberries over the dough.
