Put all dry ingredients in a bowl or kitchen robot with hook.
Mix yeast, milk and the bag of vanilla sugar together, let stand for 5 minutes.
Then add the liquid mixture, the yolks and cubes of butter and let it knead for 10 minutes, at a moderate speed until the dough comes from the edge.
Pour in a bowl, place plastic over it and let it set for minus 3 hours in a fridge so that butter can set again.
Floem the worktop, put the set ball dough on it without kneading, first push a little flour, and then roll out to approx. 1.5 cm thickness, make sure that the dough does not stick, turn it occasionally and sprinkle some flour over it during the rolling out.
Now take a large (8 cm) and smaller (3.5 cm) protruding shape, or a sturdy lemonade glass and a shots of glass, stick out the circles of dough as close as possible, then stick out the middle part. Heat the fryer between 175 and 180 degrees (remove the basket, so you have more space to bake them).
Place 3 to 4 in the Ngl pot the size of your fryer, fry them for 2 to 3 minutes on each side.
Meanwhile, put skimmer and plateau covered with kitchen paper ready, once they are baked, place them on kitchen paper and bake the rest further.
Mix everything for the icing firmly together.
If 1 by 1 half in the icing, caps the donut 1 by 1 and sprinkle the sprinkles immediately, otherwise they will no longer stick, work further.
Serve and enjoy!
