To prepare the crust, melt the butter by microwaving in 30-second increments.
In a mixing bowl, combine graham cracker crumbs, granulated sugar, and melted butter.
Firmly press the crust mixture into the bottom of a springform pan, ensuring it covers the bottom and slightly up the sides of the pan. Set aside.
In a large mixing bowl, beat the cream cheese until smooth.
Add the sweetened condensed milk, lemon juice, and vanilla extract, and mix until well combined.
Pour the cheesecake mixture into the springform pan, smoothing it out evenly.
Transfer the cheesecake to the freezer to chill for 8 hours, or overnight.
Prior to serving, thaw the cheesecake for 15-20 minutes, depending on the duration it was frozen.
Optionally, top the slices with whipped cream and fresh berries, or your preferred cheesecake topping.
