Beat 4 eggs in a mixer, add in 1 3/4 cups sugar and beat. Heat 2 cups of milk in the microwave and add to the egg mixture and beat well. Add in 1 box vanilla instant pudding, 1 (8 oz) container Cool Whip and 1 Tbsp vanilla. Mix well.
Pour mixture into a container large enough to hold 1 gallon of liquid. (We found the largest container I had with a lid and poured a gallon of water in the container to see where 1 gallon was and placed a piece of tape in that spot.) After you have poured the mixture in the container fill the container to the gallon line with milk. Put your container in the freezer and freeze over night or until set.
