Ingredients:
- 
1 1/2 cups sugar
- 
3/4 cup butter at room temperature, cut into smaller pieces
- 
3 eggs
- 
1 1/2 teaspoons vanilla
- 
3 cups flour
- 
1 1/2 teaspoons baking powder
- 
1 1/2 teaspoons baking soda
- 
1/2 teaspoons salt
- 
1 1/2 cup sour cream (sometimes I use 1/2 cup yogurt and 1 cup sour cream)
- 
Filling (see below)
- 
Glaze (see below)
Thoroughly grease bundt cake pan and preheat oven to 350 degree F.  Beat sugar and butter, then add eggs and vanilla and beat for 2 minutes.  Blend flour, baking powder, baking soda and salt in a separate bowl.  Alternately add sour cream and flour mixture to batter, on slow speed until well blended.  Prepare filling.
Spread about 1/3 of the batter in cake pan, cover with 1/3 of filling, repeat two times. Bake in 350 degree oven for 1 hour (use wooden skewer to make sure it is done – meaning it comes out clean when inserted near center of cake). Cool slightly on rack, for about 10 minutes and then invert pan, drizzle with glaze and enjoy!
 Filling:  mix 1/2 cup brown sugar with 1/2 cup finely chopped walnuts and 1 1/2 teaspoons cinnamon.
