Preheat oven to 325°F (163°C). Line a muffin tin with paper liners.
In a bowl, mix graham cracker crumbs, sugar, and melted butter. Divide evenly among the muffin cups and press firmly.
In a separate bowl, beat cream cheese, sugar, and vanilla until smooth.
Add eggs one at a time, mixing after each addition. Stir in sour cream.
Pour the batter over the crusts, filling each cup nearly full.
Bake for 18-20 minutes or until set. Let cool in the pan before transferring to the fridge for at least 2 hours.
Top with your favorite toppings and enjoy!
