This is a great cake to serve with hot spicy cider. It is moist, fruity and sparkled with spices. It is an especially fine choice as a gift from your kitchen during the holiday times. For gift giving, bake this in 4 mini-loaf foil pans, 6x3x2-inches, for about 40 minutes. Cream together butter and sugar. Beat in eggs until blended. Beat in orange, apples and pumpkin. Combine the next 4 ingredients and add, all at once, beating until blended. Spread batter into a greased 25 cm tube pan and sprinkle top with walnuts, pressing them lightly into the batter. Bake in a 350 degree oven for about 40 to 45 minutes, or until a cake tester, inserted in center, comes out clean. Allow to cool in pan and cut into wedges to serve. Serves 10.
