In a large mixing bowl add the granulated sugar and orange zest. Use your clean fingers to 'massage' the zest and sugar together until combined and very fragrant. It should look like orange sugar when done properly.
1/2 cup granulated sugar, 2 tablespoons orange zest
Add in the cream cheese and beat with an electric hand mixer until the cream cheese is smooth and combined.
2 bars (8 oz each) cream cheese
Pour in the freshly squeezed orange juice and orange extract. Beat until combined.
2 tablespoons freshly squeezed orange juice, 2 teaspoons orange extract
Stir in the Cool Whip with a mixing spoon or spatula and stir gently just until incorporated. Scrape the bottom and sides of the bowl several times to ensure that it's really well-mixed and that nothing is left there.
8 ounces Cool Whip
Spoon the filling into the Nilla wafer crust and smooth out the top.
Cover the pie dish with a lid or plastic wrap and place it in the refrigerator for at least 8 hours, or overnight is better.
When ready to serve, garnish the pie with whipped cream, orange slices, and/or whole or crushed Nilla wafer cookies. Enjoy!
