Preheat oven to 350 degrees F. Generously spray two 8×8-inch baking dishes with cooking spray. Press half of the cookie dough into the bottom of each prepared dish. Bake in preheated oven for 15 minutes. Remove and let cool completely.
Carefully remove the cookie square from one of the pans and set aside. Spread the softened ice cream evenly over the top of the cookie still inside the baking dish. Top with the other cookie square. Cover dish with foil and put in the freezer for a minimum of 3 hours.
Remove from freezer and cut into 9 equal squares. Place the chocolate chips in a small bowl, and roll the sides of the ice cream sandwiches in the chips. Wrap each sandwich in plastic wrap and place back in freezer until ready to serve.
