"[Photograph: Yvonne Ruperti] This flourless chocolate souffle cake is so creamy-chocolatey, it's practically a mousse in cake form. Notes: When served at room temperature, the texture of this cake is soft and creamy. Served chilled, the texture is more firm. Use a hot, wet, knife to cut slices of cake. Be sure to use a high quality bittersweet chocolate here.
