Creating perfect Cheesecake Bars involves a few straightforward steps:

1. Preheat the Oven: Set your oven to 325°F (160°C) and prepare an 8×8-inch baking pan by greasing it or lining it with parchment paper.
2. Make the Crust: In a bowl, mix graham cracker crumbs and melted butter until combined. Press the mixture firmly into the bottom of the prepared baking pan.
3. Bake the Crust: Bake the crust in the preheated oven for about 10 minutes, then remove and let it cool slightly.
4. Prepare the Filling: In a large bowl, combine softened cream cheese and granulated sugar. Mix until smooth and creamy.
5. Add Eggs: Beat in the eggs, one at a time, mixing well after each addition. Ensure the mixture is well combined.
6. Include Vanilla and Salt: Add the vanilla extract and salt, mixing until fully incorporated. If you prefer, add sour cream for added creaminess to the filling.
7. Pour the Filling: Carefully pour the cheesecake mixture over the crust, spreading it evenly.
8. Bake the Cheesecake: Return the pan to the oven and bake for 30-35 minutes, or until the center is set but slightly wobbly.
9. Cool: Once baked, turn off the oven and leave the cheesecake inside with the door ajar for about 30 minutes. This helps prevent cracks.
10. Refrigerate: After cooling, refrigerate the cheesecake for at least 1 hour before cutting it into bars.
11. Slice and Serve: Use a sharp knife to slice into squares and serve as desired.

These steps will guide you in crafting cheesecake bars that are not only delicious but also simple to prepare.
