Since chocolate behaves much like flour when baked, it is possible to use this basic chocolate mousse recipe to make several desserts that normally contain flour. For example, baked in a cake pan it makes Chocolate Mousse Cake. If you bake it in a jelly-roll pan, you have a chocolate roll. Baked in a soufflé mold, it is Chocolate Soufflé. For a delicious Fallen Chocolate Soufflé, the mousse is baked in a soufflé mold in a water bath (bain-marie). You can also make a wonderfully simple variation of the chocolate mousse by freezing it and serving it in slices (see Chocolate Marquise).
