Buster Bar Dessert (Ice Cream Cake)

We had a party for the August birthdays here at our house yesterday. Instead of cake for dessert I decided to make this ice cream "cake". It's a great, cool summer dessert and always a big hit!Buster Bar Dessert

1 lb. chocolate sandwich cookies, crushed
1/2 cup butter or margarine
1/2 gallon of ice cream, softened slightly
1 cup peanuts, chopped
1/2 cup butter or margarine
2/3 cup chocolate chips
2/3 cup powdered sugar
1 can (12 oz.) evaporated milk
1 tsp. vanilla

Mix crushed cookies and 1/2 cup butter or margarine. Pat into 9 x 13 " pan. Freeze for a few minutes to harden. Spread softened ice cream over top of cookies. Sprinkle peanuts over ice cream. Place in freezer. Mix 1/2 cup butter or margarine, sugar, chips and evaporated milk in a saucepan. Boil, stirring constantly, 5 to 8 minutes until thick. Cool and add vanilla. Once cool, pour over ice cream mixture. If it's not cool, it will melt the ice cream. Freeze. Remove from freezer a few minutes before serving (makes it easier to cut it).
