Happiness is a "moussey" chocolate cake

Even though I swore it was too rich for a kid's birthday party, Eric and Tess insisted that I get the chocolate mousse cake. Tess couldn't have been more delighted, and she scarfed that thing down! It was almost too rich for me, but she had no trouble polishing off her piece.

(Paul is reaching over with a napkin there. Tess is single-minded in her purpose.)
