In a large bowl mix together cream cheese, sour cream, vanilla bean paste and sugar on low speed just until combined. Scrape down the sides of the bowl with a spatula. Add the eggs and mix again on low speed just until combined. Do not overmix! Fold in the melted white chocolate.
Pour cheesecake mixture over the graham cracker crust and place the cheesecake into the oven on the center rack. Fill a pan that's larger than your cheesecake pan halfway with lukewarm water. Place on the rack below cheesecake. Bake for 45-50 minutes. When the cheesecake is done, edges will be a light golden brown and the center will be jiggly when shaken. Do not open the oven door while baking, sudden drafts will crack the cheesecake.
Turn the oven off and crack the door, leave cheesecake in the cracked oven for 1 hour. Remove from the oven and let the cheesecake come to room temperature before covering and placing in the fridge for 8 hours or overnight.
