For the Crust:

1. 1. Preheat your oven to 325°F (160°C).
2. 2. In a mixing bowl, combine crushed graham crackers and melted butter until well mixed.
3. 3. Press this mixture firmly into the bottom of each muffin liner—about one tablespoon per cup.

For the Filling:

1. 1. In a separate bowl, beat together cream cheese and sugar until smooth.
2. 2. Add vanilla extract and eggs one at a time, mixing well after each addition until you have a silky batter.
3. 3. Spoon the cream cheese mixture over your crusts in each muffin tin liner, leaving some room for rising.
4. 4. Bake in your preheated oven for about 18-20 minutes or until the centers are just set but still slightly jiggly.
5. 5. Let them cool completely in their tin before transferring them to the fridge to chill for at least two hours.
