2 cups sugar
4 large eggs, room temperature
2 tsp. vanilla extract
3 cups all-purpose flour
1 tsp. baking soda
1 tsp. salt
2 cups sour cream
4 tablespoons ground cinnamon
1 cup chopped pecans
Add eggs one at a time, beating well after each addition. Mix in the vanilla extract.
In a medium bowl, whisk together the flour, baking soda, and salt. Gradually add the dry ingredients to the butter mixture, alternating with the sour cream, mixing just enough after each addition to keep the batter smooth.
In a small bowl, combine filling ingredients: cinnamon, chopped pecans, and ½ cup of sugar.
Spoon a layer of batter into a greased 10-inch tube pan.
Sprinkle part of the filling over the batter, making sure filling doesn't touch pan itself. Repeat layering with batter followed by the remaining nut mixture, ending with batter.
Bake at 350°F for 60-65 minutes (I found 50-55 minutes to be long enough in my oven) or until a toothpick inserted in the center comes out clean.
Cool for 15 minutes before removing the cake from the pan. Sprinkle with additional cinnamon and sugar blend. Allow to cool completely before serving.
