Yum Yum Coffee Cake

Another from my mother; I'm not sure where it comes from originally but the cake turns out fluffy and light - mmmmm!


½ C marg (softened)
1 C sugar
2 eggs
2 C flour
1 tsp baking powder
1 tsp soda
½ tsp salt
1 C sour cream/buttermilk
1 tsp vanilla

Cream together marg and sugar. Add eggs one at a time. Mix dry ingredients in a separate bowl, then add to marg/sugar mixture alternately with the sour cream. Lastly add the vanilla. Spread half the batter into a greased 9x13 inch pan. Sprinkle half the filling (1/3 C brown sugar, ¼ C white sugar, 1 tsp cinnamon, 1 C chopped nuts) then spread remaining batter over that. Lastly put the remaining batter on top. Bake at 325 for 30-35 minutes - til inserted toothpick comes out clean
