Place candy canes in a plastic bag and hammer into 1/4-inch chunks or smaller. Melt the chocolate in a double boiler. Combine candy cane chunks with chocolate (add peppermint flavoring at this point if desired). Pour mixture onto a cookie sheet layered with parchment or waxed paper and place in the refrigerator for 45 minutes or until firm. Remove from cookie sheet and break into pieces (like peanut brittle).
