Sourdough apple cake

1 cup sourdough starter
2 eggs
1/3 cup oil
3/4 cup sugar
1/2 teaspoon salt
1 teaspoon baking soda
1 teaspoon cinnamon
1 cup chopped walnuts (optional)
2 cups chopped apples ( I used two large ones)

Combine the sourdough and the eggs and oil, stir well. Add the dry ingredients stirring well and then stir in the apples and walnuts. Pour into a greased square pan or 9 inch cake pan with removable sides.

Topping:

1/2 teaspoon cinnamon
1/2 cup brown sugar
2 tablespoons butter or margarine
1 tablespoon flour

Mix these ingredients together, cutting the margarine into pea sized pieces.

Sprinkle the mixture over the top of the batter spreading to cover the whole top of cake. Preheat oven to 350º and bake for 40-45 minutes or until tester inserted comes out clean.
