Preheat the oven to 350°F (175°C).
Make the crust: in a bowl combine 1½ cups Nabisco Famous Wafer crumbs, 1 tablespoon sugar, and 6 tablespoons melted butter. Press the mixture firmly and evenly onto the bottom of a 9-inch springform pan.
Bake the crust at 350°F for 8 minutes. Remove from the oven and let the crust cool on a wire rack. Keep the oven set to 350°F for the cheesecake.
In a large bowl, fit an electric mixer with the paddle attachment. On low speed, beat one 8-ounce package Philadelphia cream cheese, 1/3 cup of the sugar, and 1/4 cup cornstarch together until smooth and creamy, about 3 minutes, scraping down the bowl once or twice.
Add the remaining three 8-ounce packages of cream cheese one at a time, beating well and scraping down the bowl after each addition.
Increase the mixer speed to medium and beat in the remaining sugar (1 1/3 cups). Add 1 tablespoon vanilla extract and mix until combined.
Add the 2 eggs (large or extra-large), one at a time, beating well after each egg is added.
Add 3/4 cup heavy whipping cream and mix only until the batter is completely blended. Do not overmix.
Scrape the batter into the cooled crust and smooth the top. Wrap the sides of the springform pan in a double layer of aluminum foil to prevent water from seeping in.
Place the wrapped springform pan in a large shallow pan. Pour hot water into the outer pan so it comes about 1 inch up the side of the springform (water bath).
Bake at 350°F until the edges are light golden brown, the top is light gold, and the center barely jiggles when the pan is gently shaken, about 1 hour 15 minutes. If the top still seems uniformly soft, bake 10 minutes longer.
Carefully remove the springform from the water bath, unwrap and discard the foil, and transfer the pan to a wire rack. Let the cheesecake cool on the rack for 2 hours.
After cooling, refrigerate the cheesecake until fully cold before serving.
