BEAT cream cheese, sugar and vanilla in large bowl with electric mixer on medium speed until well blended. Add sour cream, mix well. Add eggs, one at a time, beating on low speed after each addition just until blended. Remove 1 cup of the batter; set aside. Stir melted chocolate into remaining batter in large bowl; pour over crust. Top with spoonfuls of the remaining 1 cup plain batter; cut through batters with knife several times for swirled effect.
