Sweet Potato Cake
2 1/4 cups sifted cake flour
3 teaspoons baking powder
1/2 teaspoon baking soda
1/2 teaspoon salt
1 1/2 teaspoons ground cinnamon
1/2 teaspoon ground allspice
1/2 teaspoon ground ginger
1/2 cup butter
1 cup dark brown sugar
1 cup white sugar
3/4 cup buttermilk
3/4 cup mashed sweet potatoes
1/2 cup chopped golden raisins
1 Preheat oven to 350 degrees F (175 degrees C). Grease two 9 inch round cake pans.
2 Sift together flour, baking powder, soda, salt, cinnamon, allspice, and ginger.
3 Mix together buttermilk, potatoes, and raisins in a medium bowl.
4 In a large bowl, cream butter or margarine. Gradually add white and brown sugars, creaming until fluffy. Add eggs one at a time, beating thoroughly after each addition. Beating only until smooth after each addition, alternately add dry ingredients in fourths and potato mixture in thirds to creamed mixture. Turn batter into prepared pans, and spread evenly.
