Recipe(tried): Sourdough Chocolate Cake, great

Sourdough Chocolate Cake

1 cup sourdough starter, fed in advance
1 cup lukewarm milk or evaporated milk or water
2 cups flour

1 1/2 cups sugar
2/3 cup oil
2 tsp vanilla
1 tsp salt
1 1/2 tsp baking soda
1/2 cups cocoa
2 eggs

Add starter, lukewarm milk, or water, and flour to an old yogurt container or bowl (do not use metal bowl). Place on water heater (or in warm place) for 3 hours until bubbly.

Cream sugar, oil, vanilla, salt, soda and cocoa. Add eggs, one at a time, beating well after each, adding lots of air. Combine mixtures just till combined. If sponge is has lumps, make sure to break them up when combining, otherwise large white globs remain and bake into cake.

Pour batter into prepared pan(s) (I use two greased cake pans, my celebration pan (tube pan), or one 13x9-inch pan). Bake in 350 oven for 40 min (or longer if baking in one big pan) until cake pulls away from sides of pan.

Chocolate Frosting

3 oz unsweetened chocolate
1/4 cup butter
1/4 cup half and half
1/4 cup packed brown sugar
1/4 tsp salt
1 tsp vanilla
3 cups powdered sugar

In a large saucepan, combine chocolate, butter, half and half, brown sugar and salt. Stir over medium heat until mixture almost comes to a boil and chocolate melts. Stir in vanilla. Gradually beat in enough powdered sugar (about 3 cups) to make a smooth, spreading consistency.

Or, more interesting, using a white frosting with some melted white chocolate in it.
