Line an 8 x 8 pan with aluminum foil. Cover the bottom and sides of the pan. Spray foil with nonstick cooking spray.
Combine the dark chocolate chips and sweetened condensed milk in a double boiler over medium heat. Heat until melted. *If you do not have a double boiler pan set, you can heat a 2 QT pan of water, and place a large glass or metal bowl containing the chocolate chips over it to melt the chocolate chips.
Stir mixture until smooth, then add peppermint extract. Stir well until combined.
Immediately pour mixture into your foil-lined pan. Use a spatula to smooth the surface, then sprinkle on the crushed candy canes.
Refrigerate for 2 hours, or until set and hardened. Cut into small squares and enjoy..in moderation..yes, it will be difficult!
