Pour the ice cream base into the frozen canister and turn on the machine. Drop the butter flavoring and peppermint through the opening in the top of the machine. Slowly drizzle in the melted chocolate; it will form into flecks in the churning cream. Continue to spin the ice cream until thick and creamy.

Pack the ice cream into a storage container, press a sheet of parchment directly against the surface, and seal with an airtight lid. Freeze in the coldest part of your freezer until firm, at least 4 hours.
