Preheat oven to 350 degrees. Grease a 5 1/2" x 9" loaf pan. In double boiler, melt together chocolate, coffee & sugar over low heat. Set aside to cool for 10 minutes. Turn mixture into a medium bowl, and with an electric mixer, add butter until incorporated. Add eggs one at a time. Add rum now, if using it. Pour mixture into the loaf pan; bake 1 hour until the mixture is puffed & cracked. Cool to room temp on a rack, then refrigerate overnight.

To serve:In a bowl, whip the cream until it holds stiff peaks. Use an ice cream scoop & shape the chocolate into balls. Fit a pastry bag with a star tip & pipe each boule with a coating of whipped cream.

**************Lazy Way To Serve************************************ Skip the whipping cream. Buy the aerosol stuff or the tub. Have everyone scoop out what they want & squirt the whipped stuff on. Tastes every bit as good if you aren't worried about presentation.
