1. Prep the Pan and Oven

• Preheat oven to 325°F (165°C).

• Line an 8×8-inch baking pan with parchment paper, allowing some overhang for easy removal.

2. Make the Graham Cracker Crust

• In a medium bowl, mix together graham cracker crumbs, sugar, and melted butter until fully coated.

• Press firmly into the bottom of the prepared pan.

• Bake the crust for 10 minutes, then remove and let cool slightly.

3. Prepare the Cheesecake Filling

• In a large mixing bowl, beat cream cheese and sugar together until smooth and lump-free.

• Add eggs one at a time, beating well after each addition.

• Mix in vanilla extract and sour cream until fully combined.

4. Assemble and Bake

• Pour the cheesecake mixture over the cooled crust and spread evenly.

• Sprinkle chocolate chips evenly across the top.

• Bake for 35–40 minutes, or until the center is just set and firm to the touch.

5. Cool and Slice

• Let the bars cool completely in the pan, then refrigerate for at least 1 hour before slicing into squares.
