Sour Cream Coffee Cake

I have made this cake for the past 33 years.
Since this is a place I can always search for my "stuff" I am posting the recipe

Sour Cream Coffee Cake (Kathleen recipe)

Cream 2 sticks of butter with
            2 cups sugar until light and fluffy
Add     2 eggs

Add 2 cups flour (plain)
        1 tsp baking powder
        1 tsp salt

Add 1/2 tsp vanilla
         1 cup sour cream

Pour 3/4 of the batter into a greased, floured bundt pan (or tube pan)

Sprinkle on topping made from 3/4 cups finely chopped pecans
                                                    1/4 cup brown sugar
                                                     2 tsp cinnamon and
                                                     2 tsp vanilla
Add the rest of the batter
Bake at 350F (180C) for 60 minutes

I would include a picture; but half is in the freezer and the other half mysteriously disappeared. ^.^
