½ c margarine Ð or butter
1 c, plus 1 Tbs sugar
½  tsp salt
1 tsp vanilla
2 eggs separated (I use 3 eggs)
1 ½ c, plus 1 Tbs flour
1 tsp baking powder 
1/3 c milk
1 ½ c, plus extra ¾ c fresh blueberries

Pre-heat oven to 350 degrees. Grease 8 or 9 inch pan and set aside. (I use a rectangular pan 10 ½L X 7W X 1 ¾D)

Separate eggs and beat whites until soft adding ¼ c sugar (1 Tbs at a time) until stiff (I sometimes add 1/8 c cream of tartar to try to stiffen them).

Cream margarine and sugar (¾ c), adding salt, vanilla and egg yolks.

Combine 1 ½ c flour and baking powder. Add alternately with milk to egg mixture. Coat berries with 1 Tbs flour (I omit that); add to batter.

Fold in egg whites.

Pour into prepared pan and sprinkle with remaining berries. (I then sprinkle sugar on top). Bake 50 minutes or until a toothpick comes out clean.
