Line the bottom of your pan with fruit that has been mixed with sugar - to taste. For the batter - mix together 1 stick of margarine, 1 cup flour, 1/2 cup sugar, 1 tsp. baking powder, 1/4 tsp salt, 1/2 cup milk, 1tsp vanilla. Pour batter over fruit.
In a glass cup - combine 1 cup sugar and 1/2 cup water - microwave until dissolved. Pour this sugar water over the batter in narrow rows back and forth.
Bake for 1 hour at 350 degrees.
*****Note - I always double the batter mixture because I usually use a large pan for my cobbler. If you are using a 9 inch pan - the single batch of batter will be fine. I do not ever double the sugar water mixture - the single batch is fine even for a large cobbler.
