5. Remove from heat.
6. Add bittersweet chocolate; let stand 1 minute.
7. Whisk until melted and smooth. Stir in vanilla.

9. Place alternate scoops of chocolate-chocolate chip ice cream, chocolate fudge brownie ice cream, and cookies-and-cream ice cream in single layer in cooled crust.
10. Drizzle 1/2 cup chocolate sauce over ice cream. Freeze pie until sauce sets, about 10 minutes. Top pie with scoops of remaining ice cream, alternating flavors and mounding in center.
