Authentic Italian Ricotta Cheesecake

Gather all ingredients.

Preheat the oven to 350°F (175°C). Grease a 9-inch springform pan.

In a mixing bowl, blend the cream cheese and ricotta cheese until smooth.

Add eggs, sugar, butter, flour, cornstarch, lemon juice, and vanilla; mix well.

Stir in sour cream, then pour the mixture into the prepared pan.

Bake for 1 hour. Turn off the oven and let the cheesecake cool inside with the door closed for an additional hour to prevent cracking.

Chill the cheesecake completely in the refrigerator before serving.
