2 c. soft butter
2 c. light brown sugar
4 eggs
2 tsp. vanilla extract
2 c. sour cream
4 c. flour
2 tsp. baking powder
2 1/2 tsp. baking soda
1 1/2 tsp. powdered cardamom
1/2 tsp. salt

NUT MIXTURE:

1/4 c. light brown sugar
1 tbsp. cinnamon
1/2 c. chopped walnuts

Cream butter and light brown sugar together until light and fluffy. Add eggs and vanilla, beat in well. Sift dry ingredients together and add alternately with sour cream, beginning and ending with flour. Fold in each addition just enough to blend. Don't beat or otherwise over mix. Spoon 1/3 the batter into a well buttered tube or bundt pan. Then half the nut mixture, then remaining nuts and remaining batter. Bake 1 to 1 1/2 hours at 350 degrees until brown on top and dry when you insert a probe all the way down.
