Activate the yeast

• Combine the warm milk, yeast, sugar and vanilla in a bowl.
• Let it sit until foamy.

Make the dough

• Add the egg, flour and salt and mix into a dough.
• Knead for 10 minutes.

Knead in the butter

• Add the softened butter and knead for another 8 minutes, until smooth and elastic (a mixer works too).

First rise

• Cover and rest the dough in a warm place until doubled in size.

Roll and cut

• Roll the dough out to 1.5 cm thickness.
• Cut out donut rings with a cutter and a small hole in the middle.
• Rest for another 15 minutes.

Fry the donuts

• Heat the oil over medium heat; the donut should bubble to the surface.
• Fry the donuts, flipping once, until golden on both sides.
• Drain on a cooling rack.

Ice the donuts

• Melt the white chocolate.
• Wait until the donuts are fully cool, then dip or spread the icing on top.
