In a mixing bowl, add warm milk, sugar, and instant yeast. Whisk using a hand whisker until most of the sugar dissolves.
Add vanilla extract, melted butter, and egg at room temperature. Mix until perfectly combined.
Then add all-purpose flour and salt. Mix using your hands until a perfect dough is formed.
Transfer the dough to a lightly greased pan, apply a thin oil coating on the dough ball, cover it with a clean kitchen towel, and leave it to proof for 1 hour.
After one hour, press the dough to reduce bubbles and cut it into 10 doughnuts.
Roll them into small golf size balls then shape the dough into long sausage shapes.
Now shape them into knots or plaited shapes and place each doughnut on a separate piece of parchment paper to easily carry them. I suggest you watch the video for the exact twisting tutorial.
Cover the doughnuts with a clean kitchen towel and leave to proof for the second time for 30 minutes.
Pour oil into a pan over medium heat. Once the oil is hot, add the doughnuts carefully and fry until golden brown, then flip and continue to fry until completely golden brown.
Once the doughnuts are ready, remove them from the oil and coat them with a mixture of sugar and cinnamon.
