Prepare the Base: In a large mixing bowl, beat the softened cream cheese and orange Jell-O powder together using a hand mixer. Mix on medium speed until the texture is completely smooth and creamy — this step ensures that the orange flavor fully blends into the filling.
Add the Sweetness: Pour in the powdered sugar and a splash of vanilla extract. Continue mixing until everything is fully incorporated and velvety in texture.
Fold in the Cool Whip: Add one container of Cool Whip to the cream cheese mixture and beat until smooth and airy. Then, gently fold in the second container by hand with a spatula. Folding helps maintain the light, fluffy texture that gives this pie its signature melt-in-your-mouth feel.
Fill the Crust: Spoon the creamy orange filling into your prepared graham cracker or chocolate crust, spreading it evenly to the edges. Smooth the top for a neat, bakery-style finish.
Chill and Set: Cover the pie and refrigerate for at least 4 hours, or overnight for best results. This allows the filling to set up perfectly while keeping it cool and refreshing.
