Freindship Cake starter

One of my good friends gave me a piece of this starter years ago and literally I baked my head off. I think I had a piece of this starter cake for a couple of years until everyone I knew was fed up with it. It has been at least 15-20 years since then and just recently someone asked me if I had the recipe so here it is. This one is a keeper.

Ingredients

Yield 2 -8 or 9 inch loaf pans

• 1/2 teaspoon active dry yeast
• 1 fluid ounce warm water
• 1 tablespoon white sugar
• 1 tablespoon distilled white vinegar
• 1/2 teaspoon salt
• 3 cups all-purpose flour
• 3 cups milk
• 1 cup sourdough starter
• 2/3 cup vegetable oil
• 1 1/2 teaspoons baking powder
• 1/4 teaspoon baking soda
• 3 eggs
• 1 cup white sugar
• 2 cups all-purpose flour
• 1/4 teaspoon salt
• 2 teaspoons vanilla extract
• 1 cup chopped walnuts

Directions

1. To Make Starter: Dissolve yeast in warm water. Add 1 tablespoon white sugar, 1 tablespoon vinegar, 1/2 teaspoon salt, 1 cup of the flour, and 1 cup of the milk in a non-metal bowl and stir with a non-metal spoon until creamy. Cover bowl with plastic wrap and let stand in a warm place for two days to ferment. It will become bubbly and have a sour odor. Do not place in refrigerator. On second day, third day, and fourth day: stir. On fifth day, add 1 cup flour, 1 cup sugar, 1 cup milk, and stir. On sixth, seventh, eighth, and ninth day: stir. On tenth day add 1 cup flour, 1 cup sugar, and 1 cup milk. Reserve 1 cup starter; pour remaining starter, 1 cup each, into 3 containers to give away to friends if desired. Starter is enough for 8 loaves.
2. To Make Cakes: Preheat oven to 350 degrees F (175 degrees C). Grease two 8 or 9 inch loaf pans.
3. Mix 1 cup of the starter, oil, baking powder, eggs, 1 cup of the sugar, 2 cups of the flour, 1/4 teaspoon of the salt, vanilla, and chopped nuts. Stir in the baking soda just before pouring the batter into the prepared pans.
4. Bake at 350 degrees F (175 degrees C) for 45 minutes to 1 hour. Bananas, dates, or raisins can be added for variety.
