Mix in vanilla extract. Bring cream to simmer in heavy small saucepan. Reduce heat to low. Add chocolate and stir until mixture is melted and smooth. Remove from heat. Pour half of cream cheese mixture into crust. Spoon half of chocolate mixture over by tablespoons, spacing evenly. Using tip of knife, swirl chocolate mixture into filling. Spoon remaining cream cheese mixture over. Spoon remaining chocolate mixture over by tablespoons. Swirl into filling. Bake until sides are set and center moves slightly when pan is shaken, about 1 hour 5 minutes. (Cake may crack.) Cool in pan on rack. Chill overnight. Using small knife, cut around pan sides to loosen cake. Release pan sides. Drizzle 1/4 cup caramel sauce over top of cake. Garnish with whole pecans. Pass remaining sauce separately.
