This is a recipe handed down from my paternal grandmother who came over from England on a ship. Actually my grandparents tried to get tickets for the Titanic but they were sold out and had to wait for the next ship that was leaving a week later. Thank God!
Combine all dry ingredients in a medium bowl. Cut butter into dry ingredients(very finely cut).
In another bowl combine milk, vinegar and vanilla. Beat together and add half of the dry ingredients, combining well. Butter a pie plate, spread batter evenly in it. Sprinkle rest of dry ingredients on top of the coffee cake batter. Bake at 350 degrees x 30 -35 minutes. Let cool slightly til just warm and cut.
