Preheat oven to 325 degrees and spray a spring form pan with non stick cooking spray. I prefer to use the kind that is specific for baking and has flour mixed in. This type of spray has never failed to release beautifully.
Combine half and half with white chocolate chips in a large glass bowl or measuring cup. Microwave in 15-30 second increments, stirring between each. Microwave only until mixture is mostly melted. If the mix seems to seize up (thicken, harden or clump) this indicates that the temperature is too high. You can save it by adding a touch of cool heavy cream to bring the temperature back down and stirring until the mix becomes smooth and glossy again.
In the bowl of a stand mixer fitted with the paddle attachment, beat the cream cheese until smooth and free of any lumps. You will need to stop the mixer and scrape down the sides and bottom of the bowl several times to fully aerate the cream cheese properly. This step is important in obtaining a creamy cheesecake filling.
Add the sugar to the cream cheese and mix until smooth and creamy, scraping the sides and bottom of the bowl to ensure everything is incorporated.
Add the eggs one at a time, mixing well between each addition.
Add the vanilla extract and melted white chocolate and mix to fully combine all ingredients.
Pour cheesecake mixture into prepared spring form pan and place in preheated oven for approximately 1 hour. At the 1 hour mark turn the oven off and prop the door open slightly, leaving the cheesecake for an additional hour. At this point remove the cheesecake to a wire rack to cool to room temperature and then move to the refrigerator to chill for at least 8 hours or over night.
