Combine Oreo crumbs and melted butter. Press into a 9-inch springform pan and chill while you prep the filling.
Melt white chocolate in the microwave in 30-second bursts, stirring between each until smooth. Cool slightly.
Beat cream cheese until smooth. Add sugar and vanilla, beat again.
Gradually beat in the melted white chocolate.
Whip the cream in a separate bowl until stiff peaks form, then fold into the cream cheese mixture.
Gently fold in raspberries—some may break, and that’s fine.
Pour the filling over the crust. Smooth the top and chill at least 6 hours, preferably overnight.
Garnish with extra raspberries and chocolate curls before serving, if you’re feeling fancy.
