- Split your dough into about 24 balls and flatten out. Stuff each piece with a square of chocolate and roll up, sealing any gaps.
- Arrange the balls around a small bowl on a baking tray in a wreath shape. Cover with oiled cling film and leave to rise for 1 hour in a warm place. Once it's risen, brush with the egg and sprinkle with sugar. Bake for 25-30 minutes.
- Once baked, drizzle the melted chocolate over the bread and sprinkle on the hazelnuts. Serve up!
