- Nonstick vegetable oil spray
- 1 1/3 cups finely ground amaretti cookies (Italian macaroons) plus 1/2 cup coarsely crushed cookies
- 1 tablespoon sugar
- 2 pinches of salt
- 1/4 cup (1/2 stick) unsalted butter, melted
- 3 pounds firm but ripe peaches, halved, pitted, cut into 3/4-inch-wide wedges
- 1 cup (packed) plus 1 tablespoon golden brown sugar, divided
- 1 1/2 tablespoons fresh lemon juice
- 2 1/4 quarts vanilla ice cream (9 cups)
- 2/3 cup chilled heavy whipping cream
- Even easier: Use purchased peach ice cream instead of mixing up your own.
- Ingredient info: Amaretti cookies are available at supermarkets and Italian markets.
- Preheat oven to 350°F. Coat 9-inch glass pie dish with nonstick spray. Mix finely ground cookie crumbs, 1 tablespoon sugar, and pinch of salt in medium bowl. Add lukewarm melted butter; mix to blend. Press crumbs onto bottom and up sides of dish. Bake until golden around edges, about 10 minutes. Cool completely in dish on rack.
- Preheat broiler. Line rimmed baking sheet with foil. Coat with nonstick spray. Arrange peaches in even layer on sheet. Broil until beginning to brown, watching closely to avoid burning, 3 to 5 minutes. Sprinkle 1/4 cup brown sugar over peaches. Broil until sugar melts and caramelizes, rotating sheet for even cooking, 2 to 3 minutes longer. Transfer peaches and juices to bowl (leave any burned parts behind). Add 3/4 cup brown sugar, lemon juice, and pinch of salt to peaches; stir until sugar dissolves. Cover; chill until cold, about 2 hours.
- Slightly soften ice cream in microwave on low power in 20-second intervals. Transfer to large bowl. Add broiled-peach mixture. Fold to incorporate peaches (peaches will break apart). Spoon about 2/3 of ice cream into cooled crust; smooth top. Cover and freeze pie and remaining peach ice cream separately until firm, about 4 hours. Using medium-size ice cream scoop, scoop remaining ice cream in bowl in level coops and arrange in concentric circles top pie. Freeze pie. DO AHEAD: Can be made days ahead. Cover and keep frozen.
- Using electric mixer, beat cream and remaining 1 tablespoon brown sugar in medium bowl until peaks form. Sprinkle coarsely crushed amaretti cookies over pie. Cut into wedges and serve with dollop of brown sugar whipped cream.
