Here is the verison my mother passed on to me.
30 DAY FRIENDSHIP CAKE
Day 1: Pour 1 pint of starter into a glass gallon jar. Add 1 large can of peaches and juice. Chop the peaches into pieces. Add 2 1/2 cups sugar and stir every day for 10 days. Cover the jar with a saucer and leave setting out. Do not cover with a lid and do not refrigerate.
Day 10: Add 1 large can of chunk pineapple and juice with 2 1/2 cups sugar. Stir every day for 10 days. Your color has changed and your fruit will foam when it is stirred.
Day 20: Add 2 small jars of cherries sliced in half. Add 2 1/2 cups sugar and stir a final 10 more days. The cherries will give your juice a pink color.
Day 30: You are ready to bake your cakes. You will need ingredients for 3 cakes; one for you and 2 for your friends. You need 3 boxes of yellow cake mix, 3 boxes of vanilla instant pudding, 1 dozen eggs, Wesson oil, 1 box (3 cups) raisins, 3 packages black walnuts and 3 cups of pecans. Raisins, walnuts and pecans are optional but they are very good in the cake, any or all of them.
Step 1: Preheat oven to 325 degrees. Grease and flour a tube pan. If you have 3 pans you can bake all three at one time. Bake 55-65 minutes.
Step 2: Drain fruit into large bowl. Pour juice into 3 pint jars. These are your new starters, one to keep and two to give away to friends. Cake must be started within 3 days with new starter.
Step 3: Pour 1 box of cake mix, 1 box of vanilla instant pudding, 4 eggs, 2/3 cup Wesson oil, 1 1/2 cups fruit into large bowl. Mix well. If needed add 1/2 cup water. Add 1 cup raisins, 1 package black walnuts, 1 cup pecans lightly floured to cake mixture. Pour into pan and bake as directed.
Glaze: 1 (3 ounce) package cream cheese, confectioners' sugar (1 pound) milk and 1 teaspoon vanilla. Mix well and pour on cake while warm.
