LINE 9x5-inch loaf pan with foil, with ends of foil extending over long sides of pan. Mix Crust Mix, butter, 2 Tbsp. of the flavored instant coffee and the sugar with fork in medium bowl until crumbs are evenly moistened. Press 1/2 cup of the crumb mixture firmly onto bottom of prepared pan; reserve remaining crumb mixture for later use.
BEAT milk, Filling Mix and the remaining 2 Tbsp. flavored instant coffee in medium bowl with electric mixer on low speed until blended. Beat on medium speed 3 min. (Filling will be thick.) Gently stir in whipped topping. Spoon one-third of the whipped topping mixture over crust in pan; sprinkle with one-third of the reserved crumb mixture. Repeat layers twice. Cover tightly with additional foil.
FREEZE at least 4 hours. Lift dessert from pan, using foil handles. Let stand at room temperature 10 min. before slicing to serve. Store leftovers in freezer up to 1 week.
