Creating the Chocolate Swirl Cheesecake is a delightful experience. Follow these steps to craft your masterpiece:

1. Preheat Oven: Preheat your oven to 325°F (160°C).
2. Prepare the Crust: In a medium bowl, combine graham cracker crumbs, sugar, and melted butter. Mix well until the mixture resembles wet sand.
3. Press the Crust: Press the mixture firmly into the bottom of a 9-inch springform pan to form an even layer. Bake for 10 minutes, then allow to cool.
4. Melt Chocolate: In a small saucepan, melt the chocolate chips and butter over low heat, stirring until smooth. Set aside to cool slightly.
5. Mix Cream Cheese Filling: In a large bowl, beat the softened cream cheese until smooth. Gradually add sugar, beating until fluffy.
6. Add Eggs: Add the eggs one at a time, mixing well after each addition. Incorporate sour cream and heavy cream, ensuring everything is blended well.
7. Create Swirls: Pour half of the cheesecake mixture over the cooled crust. Drizzle half of the melted chocolate over the batter. Use a knife to swirl.
8. Layer More Batter: Pour the remaining cheesecake mixture over the first layer and repeat the chocolate drizzle and swirling.
9. Bake: Place the cheesecake in the preheated oven. Bake for 55-60 minutes or until the edges are set but the center is slightly jiggly.
10. Cool: Turn off the oven and allow the cheesecake to cool inside for 1 hour. Transfer to the refrigerator and chill for at least 2 hours (or overnight).
11. Garnish: Before serving, top with whipped cream and chocolate shavings, if desired.
