Mix 1 cup sour cream with 1 t baking soda and set aside.

Cream 1/4 pound butter and 1 cup sugar. Add 2 eggs, 2 cups sifted flour, 1 1/2 t baking powder, 1/4 t salt and 1 T vanilla.

Mix thoroughly and combine with sour cream mixture.

In another bowl make the swirl topping mix: 1/2 cup chopped nuts, 1/2 t cinnamon, 1/2 c brown sugar, 1/2 cup chocolate chips.

Pour half the batter into a greased loaf pan. Add half of the swil mixture, covering all batter. Add remaining batter and top with the rest of the swirl mixture. Use a knife to gently swirl the topping into the batter. Bake at 350* for 45 minutes to an 1 hour.

Tips: I reduced the white sugar to 2/3 cup. I reduced the brown sugar to 1/3 cup.

I used walnuts in this recipe, but you could try pecans, mixed nuts, almonds, hazelnuts, etc.

I used light margarine and light sour cream.

I used half whole wheat flour and half all purpose flour.
