I have a donut machine that cuts and fries donuts automatically.

1 1/4 sticks Unsalted Butter
4 Eggs
2 cups Milk
1/2 cup Sugar
Pinch of Salt
1 package Yeast
Enough Flour to make a firm dough
Oil for frying
Powdered Sugar
In a small bowl, combine the yeast and 1/2 cup of the milk (luke warm). Mix in 3 tablespoons flour and 1 teaspoon of the sugar. Allow this mixture to sit in a warm place for 1 hour.
Combine remaining dough ingredients then add in the yeast mixture. Mix until a smooth dough forms, then knead by hand. Allow dough to sit in a warm place until double in volume.
Knead the dough to eliminate the pockets of air. Divide dough into tablespoon size pieces. Press flat each piece of dough. Allow dough pieces to rise again for 1 hour.
