I picked this pie when I was craving a Shamrock Shake. I think you could get away with calling it a shamrock pie during the month of March and nobody would be disappointed.
From Better Homes and Gardens All-Time Favorite Pies (1978)
1 Chocolate wafer crust
6 1/2 cups tiny marshmallows
1/4 cup milk
1/4 cup green cremè de menthe
2 tablespoons white crème de cacao
2 cups whipping cream
Unsweetened whipped cream
In large saucepan, combine marshmallows and milk. Cook over low heat, stirring constantly, till marshmallows are melted. Remove from heat. Cool mixture, stirring every 5 minutes. Combine crème de menthe and crème de cacao; stir into marshmallow mixture. Whip 2 cups whipping cream till soft peaks form. Fold marshmallow mixture into the whipped cream; turn into chilled wafer crust. Freeze several hours or overnight till firm. Before serving, garnish pie with additional unsweetened whipped cream and chocolate curls.
