Preheat oven to 350 degrees. Combine first 7 ingredients in mixing bowl and blend well. Pour into greased and lightly floured 9 1/2 inch Bundt pan. Bake 45-50 minutes or until cake springs back when lightly touched.
Combine 6 tablespoons amaretto and confectioners' sugar. While cake is still warm in pan, poke holes in cake; pour liqueur mixture over. Allow cake to cool in pan at least 2 hours before removing.
