Sandwich mint chocolate chip ice cream between chocolate wafer cookies; freeze until firm. Melt 6 ounces chopped semisweet chocolate, 6 tablespoons butter and 11/2 tablespoons corn syrup in the microwave, stirring every 30 seconds. Stir in 1/2 teaspoon peppermint extract; let cool a few minutes, then dip the ice cream sandwiches in the chocolate mixture to fully coat. Freeze at least 1 hour.
