Boil water and margarine together. Add flour and blend well. Let cool. Add eggs, one at a time. Beat well. Spread into ungreased jelly roll pan. Bake at 400 degrees for 25 minutes or until lightly browned. The crust will resemble the surface of the moon with an uneven surface. While the crust is cooling, prepare the pudding as directed on the back of the box. Add softened cream cheese and beat well. Spread on top of the cream puff base. Cover with cool whip and drizzle with chocolate syrup. Cool for several hours before serving.
