4. Crumble the yeast and start mixing.
5. Add the vanilla extract.
6. Gradually add the eggs, mixing slowly.
7. Add the grated orange zest and salt.
8. Add the soft butter piece by piece, mixing until the dough is smooth.
9. Lay the dough on the work surface and fold it to incorporate air.
10. Form a ball, place in a lightly oiled bowl, cover with plastic wrap, and let rise in the oven with the light on for a few hours.
11. After rising, gently roll out the dough to about 1 cm thickness.
12. Use a pastry cutter to shape the doughnuts (classic twisted or ring shape). For rings, cut out the center with a smaller cutter.
13. Place the shaped doughnuts on a floured cloth and let rise for at least 3 hours.
