Preheat your oven to 325°F (160°C). Line a muffin tin with cupcake liners.
In a mixing bowl, combine the softened cream cheese and ½ cup sugar. Beat on medium speed with an electric mixer until smooth and creamy.
Add the sour cream, eggs, vanilla extract, and vanilla bean seeds to the cream cheese mixture. Mix until well blended and smooth.
Gently fold in the heavy cream until just combined. Be careful not to over-mix.
Divide the cheesecake batter evenly into the prepared muffin tin, filling each liner about ⅔ full.
Bake in the preheated oven for about 18-20 minutes, or until the tops are set and a toothpick inserted in the center comes out clean.
Once baked, remove the muffin tin from the oven and allow the cupcakes to cool completely in the tin. Refrigerate for at least 2 hours to set.
Before serving, sprinkle a thin layer of granulated sugar evenly over each cupcake. Using a kitchen torch or broiler, caramelize the sugar until it forms a golden crust. Be careful not to burn it.
Allow the caramelized sugar to cool and harden for a few minutes before serving.
