Creating the Chocolate Strawberry Swirl Cheesecake can be simple if you follow these easy steps:

1. Preheat Oven: Preheat your oven to 325°F (160°C). Grease a 9-inch springform pan and set it aside.
2. Prepare the Crust: In a mixing bowl, combine the chocolate graham cracker crumbs, melted butter, and granulated sugar. Press the mixture firmly into the bottom of the prepared springform pan. Bake for 10 minutes, then remove and let it cool.
3. Make the Cheesecake Filling: In a large mixing bowl, beat the softened cream cheese with an electric mixer until smooth. Gradually add the granulated sugar, mixing until well combined.
4. Add Eggs: Add the eggs one at a time, mixing on low speed until just incorporated. Do not overmix.
5. Incorporate Vanilla and Cream: Stir in the vanilla extract, sour cream, and heavy cream until the mixture is smooth and creamy.
6. Divide the Mixture: Take half of the cheesecake batter and pour it over the cooled crust, smoothing the top.
7. Mix in Cocoa Powder: Add the cocoa powder to the remaining batter and mix until fully combined. Pour this chocolate batter over the white cheesecake layer in the springform pan.
8. Prepare the Strawberry Swirl: In a small saucepan over medium heat, combine the pureed strawberries, sugar, and lemon juice. Cook for about 5 minutes until slightly thickened. Let it cool.
9. Create the Swirls: Drop spoonfuls of the strawberry mixture over the top of the chocolate cheesecake batter. Use a knife or skewer to gently swirl the strawberry puree into the batter to create a marbled effect.
10. Bake: Place the springform pan in the preheated oven and bake for 60 minutes or until the center is set but slightly jiggly.
11. Cool and Chill: Turn off the oven and crack the door, allowing the cheesecake to cool gradually for one hour. Then, refrigerate for at least 4 hours or overnight to fully set.
