Roll out the puff pastry and cut into 12 equal pieces. Place 1 piece of puff pastry in each muffin tin. Preheat the oven to 200 °C top/bottom heat.
Mix the quark with the eggs, sugar, vanilla paste and custard powder to form a smooth mixture. Fill the muffin cases with the quark mixture.
Wash the blueberries and pat dry. Place on top of the quark mixture and press down lightly.
Bake in the oven for approx. 20 minutes at top/bottom heat until golden brown. Then leave to cool in the tin so that the quark mixture can set.
