Sweet Potato Craisin Loaves

Preheat oven to 350 °F (175 °C). Generously grease two 9 x 5x 2 1/2-inch baking pans; set aside. In medium bowl combine flour, baking powder and spices, mixing well. Set aside. In large mixing bowl, beat together the sugar, syrup, sweet potatoes and butter until smooth. Add the eggs and blend well. Alternately, stir in the half and half and flour mixture to the sweet potato mixture, until just mixed. Do not over mix. Fold in the craisins and nuts. Pour into prepared pans. Bake for 45 minutes or until a wooden pick inserted in center comes out clean. Cool for 10 to 15 minutes on wire rack before removing from pans. Cool completely and wrap tightly to store.
