Preheat your oven to 325°F (165°C) and line a muffin tin with paper liners.
Mix together graham cracker crumbs, melted butter, and sugar until well combined. Press about 1 tablespoon of the mixture into the bottom of each lined muffin cup.
In a large bowl, beat the cream cheese and sugar until smooth and creamy. Add in vanilla extract, eggs, sour cream, flour, and salt, then beat until well combined.
Divide the cheesecake filling evenly over the crusts in each muffin cup.
Bake in the preheated oven for 18-20 minutes or until the center is set. Allow to cool to room temperature before refrigerating for at least 2 hours.
Notes
Top with fresh berries, whipped cream, or a drizzle of chocolate sauce for garnish.
