1. Preheat the Oven and Prepare the Muffin Tin

Set the oven to 325°F (160°C). Line a muffin tin with cupcake liners to prevent sticking and make cleanup easier.

2. Make the Crust

In a mixing bowl, combine the graham cracker crumbs, sugar, and melted butter. Stir until the mixture has the consistency of wet sand. Spoon about one tablespoon of the mixture into each cupcake liner and press it down firmly using the back of a spoon or the bottom of a small glass. This ensures a compact crust that holds together.

3. Prepare the Cheesecake Filling

In a large mixing bowl, beat the softened cream cheese, sour cream, and sugar together until the mixture is completely smooth. It is essential to use room-temperature cream cheese to avoid lumps.

Add the eggs one at a time, mixing gently after each addition. Overmixing can incorporate too much air, leading to cracks in the cheesecake.

Stir in the lemon juice, vanilla extract, and lemon zest. The lemon zest intensifies the citrus flavor, creating a bright, fresh taste. Mix until everything is well combined and the batter is smooth.

4. Fill and Bake

Spoon the cheesecake filling over the prepared crusts, filling each liner about two-thirds full. This allows room for the cheesecakes to rise slightly as they bake.

Place the muffin tin in the oven and bake for 20-25 minutes. The cheesecakes are done when the edges are set, but the center should still have a slight jiggle when shaken gently. Overbaking can result in a dry or cracked texture.

5. Cool and Chill

Once the cheesecakes are baked, remove the muffin tin from the oven and let them cool at room temperature for about 30 minutes. Then, transfer them to the refrigerator and chill for at least two hours. This step is crucial for achieving the right texture, as the cheesecakes firm up while cooling.

6. Add Toppings and Serve

Before serving, garnish each cheesecake with a dollop of whipped cream, a thin slice of lemon, or fresh berries. These additions enhance both the flavor and presentation.
