In a large HEAT PROOF bowl, put coffee, sugar, coffee and chocolate onto a pot of hot simmering water (about 1 inch of water in pan) Stir these ingrediences until well incorporated. Take off the heat and ket cool for a bit. While cooling take your egg whites and whip them into soft peaks. In another bowl, whip the cream until soft ribbins form. Stir yolks into chocolate mixture well. Using a spatula, softly fold in the egg whites, and the cream, gently folding so it does not become heavy.
During this time, unwrap all of those little cakes, and slice them into 1 inch little rolls. Line the sides of the pan with the rolls, and pour the mousse into the pan. Cover and chill for no less than 2 hours. Release from the pan and you have a beautiful yummi mousse cake!!! Enjoy!
