Crumb Coating: Line 2 (2-qt.) freezer proof bowls with plastic wrap. Mix OREO Pieces and butter; press 4 cups firmly onto bottom and up side of each lined bowl. Freeze 1 hour.

Layered Bombe: Beat cream cheese in large bowl of mixer fitted with whip attachment 1 min. or until creamy; scrape side of bowl. Gradually add 1 cup plus 2 Tbsp. coffee, mixing well after each addition. Add dry pudding mix; beat 1 min. or until well blended. Blend in whipped topping. Spread 2 cups cream cheese mixture over Crumb Coating on bottom of each bowl; sprinkle each bowl with 1/2 cup OREO Pieces.

Mix ice cream and 6 Tbsp. coffee until blended. Carefully spread over cookie crumbs.

Brush cake halves with remaining coffee. Place, coffee-side down, over ingredients in each bowl; press to fit. Cover. Freeze at least 3 hours or overnight until firm.

Unmold Layered Bombes onto cutting board; discard plastic wrap. Cut each bombe into 12 wedges, dipping knife in hot water between cuts. Return to freezer until ready to serve.

Mocha Sauce: Blend ganache and coffee until well blended. Keep warm.
