Best coffe cake ever! An oldie but goodie. I made this for my Nana’s 99th birthday.  It’s her favorite cake.

1 1/2 cups sugar, 3/4 cup butter softened, 3 eggs, 1 1/2 tsp. vanilla, 3 cups flour, 1 1/2 tsps. baking powder, 1 1/2 tsps. baking soda, 3/4 tsp. salt, 2 cups sour cream, 1/2 cup packed brown sugar, 1/2 cup finely chopped nuts, 1 1/2 tsps. ground cinnamon.

Heat oven to 350. Grease tube pan, bundt pan, or 2 loaf pans. Beat sugar, butter eggs, and vanilla in large mixer bowl on medium speed, scraping bowl occasionally, 2 minutes. Beat in flour, baking powder, baking soda and salt alternately with sour cream on low speed.  Prepare filling. (Mix brown sugar, chopped nuts & cinnamon in separate bowl.)

For tube or bundt cake, spread 1/3 cup of the batter (about 2 cups) in pan and  sprinkle about 1/3 of the filling (6 tablespoons); repeat 2 times. For loaves, spread 1/4 of the batter (about 1 1/2 cups) in each pan and sprinkle each with 1/4 of the filling (about 5 tablespoons); repeat.

Bake until wooden pick inserted in center comes out clean, about 1 hour. Cool slightly; remove from pan(s).  Cool 10 minutes.
