1. Mix the flour, sugar, yeast and 1 tsp salt together. Add the egg yolks, warm water and butter and stir to a soft dough - add an extra splash of water if you need to.

2. Knead for 5 minutes and then place the dough into a lightly oiled bowl, cover and leave for an hour until doubled in size.

3. Knead the dough lightly on a floured surface for a few seconds, and then roll into small rounds. Leave for about 10 minutes before frying

4. Heat the oil in a deep-fat fryer to 170°c/325F

5. Slip the doughnuts in a few at a time; they will sink and then bob-up again. Wait for them to brown and cook for 2 to 3 minutes. Drain and then roll in the sugar and cinnamon mix whilst still warm

6. Serve immediately

Chef Tip
Let the doughnuts cool down and dip into a frosting made with icing/confectioners sugar and water and then dip into colored sprinkles for a fun alternative to sugar and cinnamon.
