3 cups Chocolate Mousse
1/2 cup bittersweet chocolate chips
1 cup sifted cake flour
1. Pre-heat oven to 325 degrees with bain marie.
2. Prepare a 9-inch round cake pan by greasing it, lining with parchment paper, and greasing again.
3. In a large bowl, gently fold chips and flour into Chocolate Mousse. Transfer to prepared cake pan and lower pan into bain marie. Bake about 30 minutes. (A toothpick will not come out clean; this is a dense, fudgey cake.) Remove cake from oven and bain marie and let rest in cake pan for 10 minutes before slicing -- serving warm is ideal.
