Add buttermilk alternately with flour and soda. Add vanilla and Milky Way mixture and mix until smooth. Fold in pecans. Pour into greased and floured bundt pan. Bake 1 hour, or until cake tester comes out clean. Cool 15 minutes in pan, then turn out on wire cake rack. Note: The nougat texture of Milky Way makes this cake perfect as a heavy, moist foundation for scoops of ice cream. ----
