Sift in the 2 cups powdered sugar, ¼ cup cocoa powder, and ¼ teaspoon salt and add in 2 teaspoons vanilla extract and mix at low speed until the sugar is incorporated then increase the speed to high and whip for 1 minute. Scraping down the sides as needed so everything is evenly combined and there are no lumps.

Melt 8 ounces semi-sweet chocolate at 30-second intervals, stirring in between each one, until smooth. While mixing at slow speed, pour the melted chocolate into the cheesecake mixture and mix until fully combined.
Fold in the 16 ounces Extra Creamy Cool-Whip with a rubber spatula until evenly incorporated for a fluffier texture or mix in with the paddle attachment for a silkier texture.

Spread the filling mixture out in the prepared crust, the filling may come above the crust in the pan, but that's okay. Just be careful around the edges so you don't pull the crust back into the filling. Smooth out the top and cover with aluminum foil.
Chill in the refrigerator for at least 10 hours. When ready to slice, run a chef's knife under hot water to heat the blade, then slice. Clean and heat the blade after each slice for clean and even cuts.
