1. Prepare the Crust:
- Preheat your oven to 325°F (165°C).
- In a medium bowl, combine the chocolate cookie crumbs, melted butter, and sugar. Mix until the crumbs are evenly moistened.
- Press the mixture firmly into the bottom of a 9-inch springform pan. Set aside.
2. Make the Raspberry Sauce:
- In a saucepan over medium heat, combine the frozen raspberries, water, sugar, and cornstarch. Stir continuously until the mixture boils and thickens, approximately 5 minutes.
- Remove from heat and strain through a fine-mesh sieve to remove seeds. Set the sauce aside to cool.
3. Prepare the Cheesecake Filling:
- In a heatproof bowl, combine the white chocolate chips and half-and-half cream. Melt together over a pot of simmering water (double boiler method), stirring until smooth. Remove from heat and let it cool slightly.
- In a large mixing bowl, beat the softened cream cheese and sugar until smooth and creamy.
- Add the eggs one at a time, ensuring each is fully incorporated before adding the next.
- Mix in the vanilla extract.
- Gradually blend in the melted white chocolate mixture until the batter is uniform.
4. Assemble the Cheesecake:
- Pour half of the cheesecake batter over the prepared crust.
- Drizzle 3 tablespoons of the raspberry sauce over the batter. Use a knife or toothpick to gently swirl the sauce into the batter.
- Pour the remaining cheesecake batter on top. Repeat the drizzling and swirling process with another 3 tablespoons of raspberry sauce.
- Reserve any remaining raspberry sauce for serving.
5. Bake:
- Place the springform pan in the preheated oven and bake for about 55 to 60 minutes, or until the center is set and the top is lightly browned.
- Remove from the oven and allow the cheesecake to cool to room temperature.
- Once cooled, refrigerate for at least 8 hours or overnight to fully set.
6. Serve:
- Before serving, remove the cheesecake from the springform pan.
- Drizzle slices with the reserved raspberry sauce.
- Optionally, garnish with fresh raspberries or white chocolate shavings.
