Beat the eggs well to whitening with the sugar and add the milk, the baking powder and oil gradually and beat well. Sift the flour and add it in portions with the baking soda and vanilla. Optionally add walnuts.
When everything is homogenized, pour the pie mixture into a greased and floured pie form. Put to bake in moderate oven until ready.
Allow the homemade pie with milk to cool and only then release it from the form. Turn it over and sprinkle it with powdered sugar or glaze.
