Sprinkle yeast and sugar over warm water in a large bowl.
Warm together milk, butter and water until it is lukewarm and then add it to the yeast mixture.
Beat the eggs and stir into the liquids with sugar.
Stir in the flour, one cup at a time to make a stiff dough.
Divide into several containers if necessary and let rise until doubled.
Combine apples, brown sugar, and cinnamon.
When the dough has risen, heat oil to 375 F or 190 C.
Add apples over the top of the risen batter.
Take a scoop of dough, add about a teaspoon of apple mixture, and then use another tablespoon to scrape the dough into the hot oil. Fry until golden brown, turning over once.
Toss with regular white sugar or powdered sugar.
