1. Place softened ice cream in large bowl; stir until it looks like soft serve ice cream. Quickly stir in 1/4 cup peanut butter topping. (Do not overmix. You want to see streaks of the topping throughout the ice cream.)
2. Spread ice cream mixture in crumb crust. Cover; freeze 6 to 8 hours or until firm. Serve with remaining peanut butter topping. Garnish with whipped topping. Makes 8 servings.
