1 tsp. baking soda
1/2 tsp. salt
1 c. sour cream

1/2 c. chopped walnuts
2 tsp. cinnamon

Mix all topping ingredients together.

Cream together butter and sugar. Add eggs, one at a time; then the vanilla. Sift together flour, baking powder, soda and salt; add to creamed mixture; mix thoroughly. Add sour cream LAST; mix well. Spread half of batter in well greased tube pan. Sprinkle half of topping over batter; then add the rest of the batter. Top with remaining topping. Sprinkle lightly with water. Bake at 350 degrees for 40 minutes.
