Gather the ingredients.

Make crust: Mix together cookie crumbs, melted butter, and sugar in a medium bowl. Press mixture into the bottom of a 9-inch springform pan.

Make sauce: Combine raspberries, water, sugar, and cornstarch in a saucepan. Bring to a boil and continue boiling until sauce is thick, about 5 minutes. Strain through a mesh strainer to remove seeds. Preheat the oven to 325 degrees F (165 degrees C).

Make cheesecake: Melt white chocolate chips with half-and-half in a metal bowl over a pan of simmering water; stir occasionally until smooth.

Mix together cream cheese and sugar in a large bowl until smooth. Beat in eggs one at a time. Blend in vanilla and melted white chocolate mixture. Pour ½ of the batter over crust.

Spoon 3 tablespoons raspberry sauce over batter. Pour remaining cheesecake batter on top. Spoon 3 tablespoons raspberry sauce over batter. Swirl batter with the tip of a knife to create a marbled effect.

Bake in the preheated oven until filling is set, 55 to 60 minutes. Cool cheesecake at room temperature, then cover with plastic wrap and refrigerate until thoroughly chilled, 8 hours to overnight.

Remove cheesecake from the pan and serve with remaining raspberry sauce.
