Put the flour, sugar, baking powder, vanilla, eggs and egg yolk into a food processor and blend until it forms a ball. This might take some time, but be patient. Place on a lightly floured surface and knead in the nuts and aniseed. Divide the paste in two, and roll out into log shapes, about 4 cm wide. Put on a baking tray covered with baking parchment. Keep them at least 5 cm apart as they spread while cooking. Lightly glaze with a little egg wash.
