Arrange the chocolate cookies on a large tray or baking sheet with the flat side facing up.

Place a small amount of chocolate frosting or melted chocolate in the center of each cookie.

Press an upside-down miniature peanut butter cup onto each cookie to create the hat shape.

Wrap a thin candy strip around the base of each peanut butter cup to form the hat band.

Attach a candy-coated chocolate to the front of each hat using a tiny dab of frosting or melted chocolate.

Allow the cookies to sit for 10 to 15 minutes, or refrigerate briefly until the decorations are secure.

Serve immediately or store in an airtight container until ready to enjoy.
