Cook raspberries, sugar, and lemon juice until softened, then stir in the cornstarch slurry and cool completely.
Beat cream cheese, powdered sugar, and vanilla until smooth, then fold in whipped cream for a light cheesecake filling.
Mix chocolate cookie crumbs with melted butter and press into dome molds to form the base.
Fill each mold with cheesecake mixture, add the raspberry center, cover with more filling, and chill until firm.
Heat heavy cream, pour over chopped chocolate, stir into a smooth ganache, and spoon over the domes before serving.
