Chocolate Sourdough Cake

1 cup starter
1 cup milk (or evaporated milk)
2 cups flour
1 1/2 cups sugar
1 cup oil
2 tsp vanilla
1 tsp salt
1 1/2 tsp baking soda
3/4 cup cocoa
2 eggs

Preheat oven to 350 degrees Fahrenheit. Combine starter, milk,
and flour, let ferment 2 to 3 hours or until bubbly. Cream sugar,
oil, salt, vanilla, baking soda, and cocoa. Add eggs one at a
time, beating well to incorporate as much air as possible. Combine
both mixtures, trying to not deflate the sugar mixture, but make
sure the mixtures are well blended. Divide batter between two
greased nine inch cake pans and bake for 40 to 45 minutes or until
done. Cool in pans for five minutes, then turn out and finish
cooling on wire rack. Frost as desired.
