In a medium saucepan, melt the cream cheese, butter, and whole milk over low heat. (Before adding, you can cut butter and cream cheese into small cubes to help speed the process.) Set aside when completely melted.
Separate your eggs. (You will get better results if eggs are at room temperature.) Set aside six of the yolks and all of the whites for the recipe.
Line your spring-form pan with parchment paper. Make sure to wrap the bottom with foil to prevent any leakage.
To Make the Meringue
Using a stand mixer, pour your thirteen egg whites into the bowl
To help with the stability of the foamy peaks, add a ¼ t. of cream of tartar to the egg whites.
Mix on high for two minutes.
Gradually add the sugar. (This process should take about five to seven minutes.)
To Make the Cream Cheese Layer
Take the melted cream cheese mixture, and add it to the egg yolks.
Whisk together until well incorporated.
Sift in the flour, followed by the corn starch.
Add one teaspoon of vanilla.
Finish
At this point you will want to start boiling some water for a bain-marie, or water bath which will keep the cheesecake from cracking.
Combine the meringue into the flour and egg mixture, flipping over and under, over and under using a wide spatula.
Place resulting batter into the spring-form pan. (Give it a couple of swift taps on the side to get it to settle.)
Now place the spring-form pan with cheesecake mixture inside a second, larger pan.
Add hot water to the bottom pan until it is half-full.
Bake for 25 minutes at 320 degrees.
Reduce temperature to 280℉ and cook for another 55 minutes. (I added an additional 30 minutes of baking time because mine wasn’t finished.)
