Rachel, do not giggle at the name of this cake. Its very good at brunch or dinner.
Spread all ingredients into greased 9x13” pan, in order listed. (Pineapple should be a thin layer in the bottom of pan, walnuts on top.) Margarine should be sliced with a cheese cutter onto the powdered cake mix.
Bake at 350 degrees for 45-50 minutes.
