Preheat your oven to 325°F (165°C) and line a 12-cup muffin tin with paper liners.
Place one vanilla wafer cookie, flat side down, into the bottom of each muffin cup to form the crust.
In a medium bowl, combine the granulated sugar and lemon zest. Rub them together with your fingertips until the sugar becomes moist and fragrant.
Add the room temperature cream cheese to the lemon sugar and beat with an electric mixer until light and fluffy.
Add the eggs one at a time, mixing well after each addition. Then, mix in the vanilla extract and freshly squeezed lemon juice until the batter is smooth.
Spoon the cheesecake batter evenly into the prepared muffin cups, filling each about 0.67 full.
Bake for 22 to 24 minutes, or until the centers of the cheesecakes are almost set.
Remove from the oven and let cool completely in the pan on a wire rack. Transfer to the refrigerator to chill for at least 4 hours before serving.
Notes
Ensure your cream cheese and eggs are at room temperature before mixing to guarantee a smooth, lump-free cheesecake batter.
