4 oz. semi-sweet chocolate
1 tsp. vanilla extract
3 c. flour
1 1/2 c. sugar
2 tsp. baking powder
2 tsp. baking soda
2 tsp. cinnamon
1/2 tsp. ground ginger
1/4 tsp. ground cloves
1/4 tsp. nutmeg
2 c. mashed cooked sweet potatoes
1 1/2 c. vegetable oil
4 eggs
1 c. chopped nuts

Butter and lightly flour a 10 inch tube pan. Place chocolate and vanilla in a small saucepan and set covered in a larger pan that you have just filled with boiling water.

Sift together all dry ingredients and set aside. In a large bowl, heat the sweet potatoes and oil together, then beat in the eggs one by one until well blended. Slowly add dry ingredients and mix well; stir in nuts. Put 1/3 of the mixture in another bowl and stir in the chocolate, which should be melted smooth by now. Alternate the batters in tube pan, as you would with a marble cake. With a knife, cut through the 2 batters to slightly swirl together. Bake in a preheated 305 degree oven for 1 1/4 hours or until the sides have shrunk away from the pan, the top is springy, and tester comes out dry. Let cool 10 minutes and then remove from the pan and cool on a rack. (Makes a 10 inch tube cake.)
