Preheat oven to 350F degrees. Line the bottom of a 9-inch springform pan with a circle of parchment paper. Coat the bottom and sides of the pan with nonstick cooking spray.
Wrap the pan in two layers of heavy duty aluminum foil, pressing the foil tightly against the sides of the pan to ensure that there are no seams.
Melt the butter in a microwave-safe bowl. Stir in the graham cracker crumbs. Transfer the crumbs to the springform pan. Press them down onto the bottom and slightly up the sides of the pan.
Bake the crust for 10 minutes. Let it cool to room temperature.
Lower the oven temperature to 325F degrees.
In the bowl of a stand mixer fitted with the paddle attachment or using a hand mixer, beat the cream cheese, flour and sugar until smooth. Add the vanilla and lemon juice. Beat on low speed until combined.
With the mixer on low speed, add the eggs one at a time until just combined. Last, beat in the sour cream.
Pour the cheesecake batter into the prepared crust. Place the foil-wrapped springform pan into a roasting pan. Open the oven and pull out the rack, placing the roasting pan on the rack. Fill the roasting pan with boiling water until it reaches 1/3 of the way up the sides of the springform pan.
Bake 90 minutes until the cheesecake is just set. Remove from oven, but let the cheesecake stay in the water bath for another 45 minutes.
Remove the cake from the water bath. Remove the foil. Cover with plastic wrap and transfer to the refrigerator to chill.
When ready to serve, remove the cake from the springform pan and slice using a wet knife.
