Treats really don't get much easier than this no bake 3 ingredient Jello pie. It only takes a few minutes to put together and it is airy, creamy and refreshing.
Stir together boiling water and Jello for at least 2 minutes. The Jello powder should be fully dissolved and the mixture cooled a bit.
Stir in ice water for several minutes until the ice is melted and the liquid is cool. It should thicken slightly.
Fold in whipped topping until fully incorporated. Chill for 10-15 minutes if you have time. Then spoon into crust. Otherwise, pour into crust and chill or at least 2 hours or until completely set.
Garnish with additional whipped topping, cherries and sprinkles if desired. Slice and serve cold.
