Mix ½ cup of the sugar, cinnamon, and walnuts in a small bowl and set aside. Combine the sour cream and baking soda in a small bowl and set aside.
Cream the butter and remaining ½ cup sugar in a large bowl. Beat in the eggs and vanilla. Sift the flour and baking powder together and add alternately with the sour cream mixture to the butter-egg mixture.
Spread half the batter in a greased and floured 9x5-inch loaf pan. Sprinkle half the sugar, cinnamon, and nut mixture over the top and gently incorporate some of it into the batter, using a fork. Add the remaining batter, and then the remaining sugar, cinnamon, and nut mixture, blending as before.
