Pour gelatin into bowl. Add 2 1/2 cups boiling water to gelatin. Stir, until gelatin is completely dissolved, about 2 minutes. Spray pizza pan with non-stick cooking spray. Pour gelatin mixture into pizza pan. Put pan into refrigerator to chill until firm -- about 3 hours.
Remove pan from refrigerator when ready to serve. Put about 1 inch of warm water in sink. Carefully dip just bottom of pan into warm water for 15 seconds. Spread whipped topping over gelatin just before serving, leaving about 1 inch of space around outside edge of gelatin for pizza "crust".
