1/2 c. butter
3 eggs
2 c. flour (self-rising)
2 c. fresh blueberries (or dry-pack frozen)
1/2 tsp. cinnamon
1 c. sugar
1 c. (1/2 pt.) sour cream
1 tsp. vanilla
1/2 c. packed brown sugar
1/2 c. chopped nuts

Mix butter, eggs, flour, 1 cup sugar, sour cream, vanilla and add blueberries last. Mix well and pour half of batter into a greased and floured tube pan.

Mix brown sugar, nuts and cinnamon together well and pour it evenly on the half of cake batter in the pan. Pour remaining half of cake batter on top of brown sugar mixture.

Bake at 350 degrees for 40 to 45 minutes. It is good served sprinkled with confectioners' sugar.

Note: This works well in a 9 x 13 x 2 inch baking pan, also.
