Creamy Nog Punch (Non-alcoholic)

I have other punch recipes I can share but this is the only one I've made. Once I made it, no one in my family wanted me to make anything else!

1 gallon vanilla ice cream
1/2 gallon eggnog
1 teaspoon ground nutmeg
1/2 teaspoon ground cinnamon
1 (16-oz) container frozen whipped topping, thawed

Scoop ice cream into a punch bowl. Pour eggnog over ice cream and sprinkle with nutmeg and cinnamon; stir in whipped topping. Serve immediately. Stir as needed.
