Combine cooled milk with mashed potatoes, white sugar, and lard.

In a separate bowl, combine lukewarm water, sugar, and yeast.

Add beaten eggs, salt, and remaining flour to the dough.

Knead the dough until smooth and elastic.

Let the dough rise in a warm place until doubled in size.

Roll out the dough and cut out doughnut shapes.
