Using room temperature cream cheese, add the following to a large bowl: 12 oz cream cheese, ½ cup powdered sugar, 1 tsp vanilla or vanilla bean paste, and ¼ cup heavy cream.
Using an electric mixer, whip until mixture starts to come together.
Add the ¼ cup white chocolate to a small microwave-safe bowl and heat in 15 second increments until melted. To keep from over heating, once most of the lumps are gone, just continue stirring until the last few melt. Note: If using white chocolate chips, I recommend adding a tsp of heavy cream to the chips before microwaving. Add in the white chocolate and beat with the electric hand mixer until the mixture is creamy and smooth.
Fill each mini cheesecake cavity with cheesecake mixture and level off the tops using a knife or sharp edge.
Gently shake back and forth quickly to let any air bubbles escape. Allow to chill in the fridge for 2-3 hours or until set.
