Add the eggs, one at a time, beating on low speed until just incorporated.
Pour the filling over the cooled crust.
Bake for 45-50 minutes or until the center of the cheesecake is almost set.
Remove from oven and run a knife around the edges to loosen the cake from the pan.
Allow the cheesecake to cool to room temperature.
In a mixing bowl, beat the heavy cream and vanilla until stiff peaks form.
