Bring whole milk ricotta, softened cream cheese, sour cream, sugar, eggs, flour, vanilla extract, 1/2 cup melted butter into a large bowl. Mix well and beat on medium high speed (using a hand-held mixture or standing mixture) for 20 minutes.
Butter springform pan with the other 1/2 tbsp of melted butter and wrap aluminum foil around the pan to prevent leakage.
Pour cheesecake mixture into springform pan. Bring to oven and bake on the middle rack for 1 hour.
Turn off oven and let cheesecake sit in oven for 2 hours. Do not open oven - we want to cool the cheesecake slowly.
Remove cheesecake from oven. Cheesecake might be slightly jiggly in the middle. Gently release the sides of the springform pan from cheesecake.
Refrigerate cheesecake in the fridge for another 4-5 hours, or overnight, until cheesecake is firm.
Optional: top cheesecake with fresh raspberries, then sprinkle raspberries with powdered sugar. Slice and drizzle with raspberry sauce.
Serve and enjoy!
Notes
If ingredients are cold, bring it to room temperature first.
Avoid dropping the temperature of cheesecake to prevent cracking - that's why we are suggesting leaving it in the oven for 2 hours for it to cool.
Water baths can be used but it is not necessary with the cooling-in-the-oven method.
Cover cracked cheesecakes with berries and sauces! ;) It has the benefit of making cheesecake super yummy with the additional toppings!
