Preheat the oven to 325°F and line a muffin tin with cupcake liners.
In a medium bowl, combine graham cracker crumbs, 1/4 cup sugar, and melted butter. Mix until well combined.
Press about 1 tablespoon of the crumb mixture into the bottom of each cupcake liner to form the crust.
In a large mixing bowl, beat the softened cream cheese until smooth. Gradually add 1 cup sugar, mixing until well incorporated.
Add the vanilla extract and vanilla bean paste, mixing until combined.
Add the eggs one at a time, mixing well after each addition.
Stir in the sour cream and heavy cream until the batter is smooth.
Pour the cheesecake batter over the crust in each cupcake liner, filling them about 3/4 full.
Bake for 20-25 minutes or until the centers are set but still slightly jiggly.
Remove from the oven and let cool to room temperature, then refrigerate for at least 4 hours or overnight.
Before serving, sprinkle 1 teaspoon of granulated sugar on top of each cupcake. Use a kitchen torch to caramelize the sugar until golden and crispy.
