Mix the flour, sugar, baking powder, and salt in a bowl.
Add a mixture of egg and milk, beating until batter is smooth.
Holding finger over bottom of a funnel having a 3/8 to 1/2 inch hole, fill funnel with batter.
Hold funnel as near surface of heated fat as possible; remove finger and drop batter into hot fat, using a circular movement from center outward to form a spiral cake about 3 inches in diameter.
Immediately replace finger on bottom of funnel; then form other cakes (as many as will float uncrowded).
Fry until cakes are puffy and golden brown,turning once.
Lift from fat with a slotted spoon and drain for a few seconds before removing to absorbent paper.
Sift confectioners' sugar lightly over cakes
