I made the original version--with spices--first and then decided it probably would be good made into chocolate. It was. I didn't add nuts or chocolate chips.
ANY OLD BOTTLE-OF-FRUIT CAKE--original recipe found here--for chocolate version see below
1 quart of any bottled fruit, juice and all
2 cups of granulated sugar
1 cup oil
4 cups flour (not sifted)
4 teaspoons soda – mix in with fruit
1 teaspoon salt
1 teaspoon cloves
1 teaspoon nutmeg
1 Tablespoon cinnamon
1 cup nuts (optional)
1 cup raisins or chocolate chips (optional)
Blend or chop fruit and place in a large mixing bowl with sugar and oil. Add sifted dry ingredients, and if desired, nuts and /or raisins/chocolate chips. Mix together well and pour into a 9×13 inch pan and bake at 350 degrees for about 50 minutes or until a toothpick comes out clean when poked in the middle. Cool. Frost with Cream Cheese Icing. Hurry and take a big slice before anyone knows that the cake is done, or you won’t get any because it is that good.Chocolate version: Remove cloves, nutmeg and cinnamon and add 1/2 cup cocoa.
PS Last years I dumped probably four dozen jars of old fruit. What was I thinking?
