1 c. sourdough
1/2 c. oil
1 c. milk
1/2 tsp. salt
2 tsp. vanilla
1 c. flour, if needed
1 c. sugar
2 eggs
3 squares melted baking chocolate
1 tsp. baking soda
1 tsp. baking powder

To sourdough, mix in sugar, oil, and eggs. Add milk and vanilla. Add chocolate. Stir well, but do not beat hard. Fold in soda and baking powder at the very last. Flour is needed only if sourdough used is thin. Bake in 9-inch tins, 30 minutes at 350 degrees.
