Preheat your oven to 350°F (180°C), and line 2 cookie sheets with parchment paper. In a stand mixer bowl, add ½ cup of the softened unsalted butter and the sugar.
Pipe a circle of chocolate around the edge of each cookie. Divide the cookie in half with a line of chocolate, separating the two sides. Add two more lines to divide the cookie into six sections. Complete the spider web design by connecting the lines with curved lines. Allow the chocolate to set before serving.
