Preparation Steps

• Preheat oven to 325°F (163°C). Line a 9x9 inch baking pan with parchment paper.
• In a medium bowl, combine graham cracker crumbs and melted butter. Press firmly into the bottom of the prepared pan to form the crust.
• In a large bowl, beat the cream cheese and sugar until smooth and creamy. Add eggs one at a time, beating well after each addition.
• Stir in the melted chocolate, sour cream, and vanilla extract until fully combined.
• Pour the cheesecake batter over the crust in the pan and spread evenly.
• Bake for 40 minutes or until the center is set but still slightly jiggly.
• Allow to cool completely, then refrigerate for at least 2 hours before cutting into bars.
