Mint Oreo Fudge

Directions

1. Line an 8-in. square baking pan with foil, letting ends extend up sides; grease foil with 2 tablespoons butter. In a metal bowl over simmering water, melt chocolate chips, unsweetened chocolate and remaining 4 tablespoons butter; stir until smooth. Add milk, crushed candy canes and extract; stir until blended.
2. Pour half the chocolate mixture into prepared pan. Arrange cookies over chocolate, cutting to fit as needed. Stir marshmallows into remaining chocolate mixture; spread over cookies. If desired, top with additional crushed candy canes. Refrigerate until firm, about 1 hour. Using foil, lift fudge out of pan. Remove foil; cut fudge into 1-in. squares. Store between layers of waxed paper in an airtight container.
