Directions:

Chill a mixer bowl and beaters. Combine the whipping cream, baking cocoa, confectioners' sugar and rum in chilled mixer bowl.

Beat at low speed with chilled beaters. Beat at high speed until stiff peaks form, scraping the bowl occasionally; do not over beat. Spoon into a mixing bowl; sprinkle with the candy bar.

Serve immediately or freeze, tightly covered, in individual serving dishes.
