Separate the egg whites and yolks, let the whites rest in a metal bowl, allow them to warm to room temperature for about 30 minutes.
Preheat the oven at 350°F.
Fit the crust in a 9-inch springform pan and push until it adheres well.
Blend the flour with the granulated sugar in a mixing bowl, add the fromage or its substitute, then add the heavy cream, egg yolks, lemon juice, and mix.
Whip the egg whites until peaks form, then softly fold it with the egg and cheese mixture with a spatula until you have a homogeneous mixture.
Power the batter into the springform pan previously prepared with the pie crust, place it into the preheated oven and bake for 40 minutes.
Turn off the oven and leave the door slightly open for another 10 minutes. Remove the cheesecake from the oven and allow to cool completely, then let it chill in the fridge overnight.
Run a knife around the rim of the springform pan to loosen the cheesecake.
Serve, sprinkle with powder sugar and enjoy!
