Line an 8 or 9-inch pan with foil, extending the sides of the foil over the edges of the pan. Grease the foil lightly with cooking spray and set aside.

In a small saucepan, heat the evaporated milk and espresso over medium-low heat, or until coffee is dissolved. Stir in ONE (1) cup of the semi-sweet chocolate chips and the marshmallow creme. Cook and stir until melted and smooth; remove from heat and pour into a large bowl. Add the cookie crumbs and powdered sugar and stir until combined.

Press into the prepared pan in an even layer, spreading to edges of pan. Set aside.

In a large, microwaveable bowl, combine the remaining semi-sweet chocolate chips and heavy cream and microwave for about 1 minute, stirring until chips are melted. Pour ganache over the bars and spread in an even layer. Top with crushed candy canes and refrigerate for about 1-2 hours or until set. Cut into bars and serve. Store in the fridge up to one week, covered.
