Create a dough by mixing together the bread flour, powdered milk, salt, sugar, butter, whole eggs, yeast, and water. Use either a mixer or by hand.
After the dough comes together, knead it for 5 - 7 minutes.
Allow the dough to rest under cover for 1 hour.
Divide into 15g portions. Mold into balls and then rings.
Allow to prove on an oil tray, and begin heating fat to 375℉/190℃.
Heat fat to and drop the proved pieces in; they will float. When one half is sufficiently browned, turn over to cook the other side.
Remove, drain off excess oil, roll immediately in caster sugar.
