Preheat the oven to 325ºF.
Prepare the graham cracker crust. In a bowl, mix together the graham cracker crumbs, melted butter, and sugar. Transfer the crumble mixture to the 9-inch baking pan. Then, press the crumbly mixture firmly into the bottom and the sides of the pan to create a crust. Set aside.
In a large mixing bowl, beat together softened cream cheese, granulated sugar, egg yolks, freshly squeezed lemon juice, and vanilla extract using an electric mixer. Set aside.
Add the egg whites to another bowl. Beat until stiff peaks form using a clean mixer attachment. Then, gently fold into the beaten cream cheese mixture.
Transfer the cream cheese filling to the prepared graham cracker crust. Bake in the preheated oven for 30-35 minutes. Don't remove the springform pan from the oven. Turn off the oven and leave the cheesecake in the oven for one hour. Then, remove the springform pan from the oven and let the cheesecake cool to room temperature. Then, refrigerate overnight. Remove the cheesecake from the springform pan, slice, and enjoy!
