The free energy of a classical nonuniform fluid is developed in a density functional expansion defined recursively from mean field theory as a starting point. Capillary wave contributions to the structure of a two-fluid interface appear explicitly in the first order. The first order result is worked out as well in the general case of slowly varying density. Comparison with potential ensemble theory is also made.
