Grease a 10" spring form pan.
Mix the ricotta, sugar, and cream cheese together.
Add 6 eggs (one at a time and mixing between each), flour, and sour cream, lemon juice, and vanilla.
Pour batter into the pan and bake for 1 hour at 350 F.
After 1 hour, turn the oven off. Do not open the oven door and allow the cheesecake to remain in the oven for an additional hour.
Cool completely and spread with 1 can of cherry pie filling, fresh strawberries, or chocolate ganache.
