- Line a 9-inch springform pan with parchment paper. 
- Combine graham cracker crumbs and melted butter. Press mixture firmly into the bottom of the pan. Chill in the fridge while you prepare the filling. 
- In a small saucepan, combine raspberries, sugar, and lemon juice. Cook over medium heat until berries break down, about 5 minutes. 
- Stir in cornstarch slurry and cook another 1–2 minutes until thickened. Remove from heat and let cool. 
- Beat cream cheese, powdered sugar, and vanilla until smooth. 
- Add melted white chocolate and mix until combined. 
- In a separate bowl, whip the heavy cream to stiff peaks. Gently fold into the cream cheese mixture. 
- Pour half of the filling over the crust. Drizzle half of the raspberry sauce and swirl with a knife. 
- Repeat with the remaining filling and sauce. Swirl again. 
- Cover and refrigerate for at least 6 hours or overnight until set. 
- Before serving, top with fresh raspberries and white chocolate curls.
