Sour Cream Coffee Cake

This is the best one I've tried. Its been my stand by for years.

1/2 cup butter
1 cup sugar
2 eggs
1 tsp vanilla
2 cups flour
1 tsp baking soda
1 tsp baking powder
1 3/4 cups sour cream (or just use up a whole container)
Topping: 1/4 cup brown sugar
1 1/2 tsp cinnamon
1/4 cup chopped nuts (pref. walnuts or pecans)

Preheat oven 350 degrees. Grease and flour a bunting pan or 9" square. Blend first 4 ingredients. Sift dry together, and add sour cream. Spread 1/2 the batter in pan, sprinkle 1/2 the topping and cover with remaining batter. Then before you sprinkle the rest of the topping you can smear the remaining sour cream (1/4 cup) over the top of the batter (you can skip this if you preffer), then sprinkle the topping on. Bake for 45 min. Yum!

See how yummy it is!
