Preheat oven to 350 F. Prepare eight ceramic ramekins (spray or butter bottom and sides). Combine chopped chocolate, half of the sugar, heavy cream and butter in small heavy saucepan over low heat. Stir until chocolate is melted and mixture is smooth. Transfer to large bowl and let cool to room temperature, stirring occasionally Add coffee. Whisk in egg yolks and vanilla. Beat egg whites in medium bowl until soft peak forms, using electric mixer at medium speed. Slowly add remaining sugar, beating at high speed. Beat until stiff peak forms. Fold egg whites into chocolate mixture. Gently fold in bread cubes. Divide mixture evenly among prepare ramekins. Place in large baking pan. Add enough hot water to fill halfway up sides of ramekins. Bake 45 to 50 minutes or until toothpick inserted in center comes out clean. Cool ramekins slightly.
Note: (can substitute muffin pan for ramekin – in muffin pans 15-20 minutes)
