Warm all of your cold ingredients up to room temperature.
Preheat your Oven to 350°F.
Grind 20 sheets of Graham Crackers (im using 4 Cups of Pecans and 2 Tablespoons of White Sugar) in a Food Processor to a coarse sand consistency. With your food processor on, drizzle in the 8 Tablespoons of melted butter.
Press the mixture into the bottom of your 9 inch springform pan. I like to press the crust half way up the sides as well.
Bake your crust at 350°F for 15 minutes.
While your crust is baking, mix, with your hand mixer, your cream cheese and sugar just until smooth.
Blend in your milk. Scrape down sides.
Adding one egg at a time, blend until the yolks are just mixed in. Repeat with all 4 eggs. Scrape down sides between each egg addition.
Incorporate 1 cup of sour cream and 1 tablespoon of vanilla. While mixing, slowly sift in 1/4 cup all purpose flour just until combined.
Pour your Cheesecake batter into your baked crust. Turn your oven down to 300°F and bake for 1 hour.
Do not open the oven door.
After 1 hour, turn your oven off and leave the cheesecake in your oven for 6 hours. Do Not open the door.
Refrigerate for at least 4 hours, overnight is better.
