In a mixing bowl, combine warm milk and yeast. Let it sit for about 5 minutes until foamy.

Add sugar, eggs, and softened butter to the yeast mixture. Mix well.

Gradually add flour and salt to form a dough. Knead until smooth and elastic.

Cover the dough and let it rise in a warm place for about 1 hour or until doubled in size.

Roll out the dough on a floured surface to about 1/2 inch thickness. Cut out doughnuts using a doughnut cutter or cookie cutter.

Place the doughnuts on a parchment-lined baking sheet, cover, and let them rise again for about 30 minutes.

Heat oil in a deep fryer or heavy-bottomed pot to 350°F (175°C). Fry the doughnuts in batches until golden brown, flipping halfway through.

Drain fried doughnuts on paper towels to remove excess oil.

Allow them to cool slightly before glazing or dusting with powdered sugar.
