Directions
1. For the cake: Mix ingredients together by hand and pour into a greased 13×9 baking pan.
2. Bake at 350 degrees for 40 minutes (the cake may appear underdone because it is so moist).
3. Remove the cake from the oven and cool completely before adding the icing.
4. Beat the cream cheese, margarine, or butter for the icing. Add vanilla. Gradually add the powdered sugar, beating between each addition until smooth.
5. Spread on cooled cake. Refrigerate any leftovers or before serving if not serving until later.
