Frozen Peanut Butter Pie

Preparation

1. Step 1

   Reserve 1/4 cup cookie crumbs. In a bowl combine remaining cookie crumbs and butter and press into bottom and side of a 10-inch (1 1/2 quart) pie plate. Chill shell.

   Step 2

   In a heavy saucepan dissolve sugar in milk over moderate heat, stirring, and remove pan from heat. Whisk in peanut butter and vanilla until combined well and cool in a bowl set in a larger bowl of ice water, stirring occasionally.

   Step 3

   In another bowl beat cream until it just holds stiff peaks and fold into peanut-butter mixture with chopped peanuts. Turn mixture into shell, smoothing top. Sprinkle reserved cookie crumbs around edge of pie.

   Step 4

   Pipe rosettes of whipped cream decoratively onto crumbs and top rosettes with whole peanuts. Freeze pie, uncovered, until frozen hard, about 5 hours. Pie may be made 2 days ahead and frozen, covered with plastic wrap and foil after 5 hours.

   Step 5

   Let pie stand in refrigerator 30 minutes before serving.
