Place chocolate chips on a small plate and set aside.

Place 1 cookie, top side facing down, on your workspace.  Quickly, scoop about 4 ounces ice cream on the exposed side of the cookie.  Smooth out the ice cream so that it is even and close to the edge of the cookie.  Place another cookie on top of the ice cream, with the top side facing up.  Gently press down so that the ice cream is flush with the edge of the sandwich.

Roll the edges of the sandwich through the chocolate chips so that the edges are almost completely covered.  

Immediately wrap the sandwich in parchment paper or plastic wrap and place in freezer.  Repeat process with the other 2 cookies. 

Before serving, cut each sandwich in half.
