Add shortening to make melted milk chocolate smoother; stir until smooth. Stir coffee beans into melted milk chocolate until coated.
Pour milk chocolate mixture onto the prepared baking sheet, spreading mixture to the edges. Refrigerate.

Pour melted dark chocolate over refrigerated milk chocolate mixture, spreading evenly over the top. Refrigerate until set, 10 to 15 minutes.
Peel the silicone mat from the bottom of the chocolate mixture and place onto a work surface. Cut into pieces using a sharp knife. The bark will crack and break as you go.
