Crush oreo cookies in using a plastic bag and a rolling pin. (A food processor would also work fine if you have one).
In a medium bowl, combine oreo cookie crumbs and melted butter. Press into a pie pan, and set aside.
In a medium saucepan heat half and half and marshmallow fluff over low heat, stirring constantly until combined. Remove from heat and place sauce pan into an ice bath.
Once cool stir in creme de menthe and creme de cacoa. Add green food coloring, if desired.
Add one to two drops green food coloring (optional!)
In a large chilled mixing bowl, beat whipped cream using a cold whisk until stiff peaks form. Fold in marshmallow mixture.
Pour filling into prepared crust. Sprinkle with extra oreo cookie crumbs. Freeze for 2-3 hours
Creme De Menthe: Creme de menthe is a liqueur that is made with sugar and mint leaves. It comes in both clear and green varieties and has a cool mint flavor. You can find it in the Cordials section of the liquor store.
Creme De Cacao: This is a sweet chocolate-flavored liqueur. It comes in both regular and clear varieties. Most varieties average 20-25% proof.
Marshmallow Fluff: This creamy confection made of egg whites can be found in the baking aisle of your supermarket.
Oreos: Avoid premade oreo crusts which may not be big enough to hold all of your filling. For a fun twist try mint Oreos next. A chocolate graham cracker crust could also be used.
Crush cookies: No food processor? No problem! Crush in a plastic baggie with a rolling pin instead.
Cool: Cool the marshmallow mixture in an ice bath so it doesn't melt the remaining ingredients.
Remove From Heat: Always remove your saucepan from the heat before adding alcohol to reduce the risk of it catching on fire.
Easily cut perfect slices using a sharp knife dipped in hot water.
Garnish with more cookies, chocolate syrup, chocolate chips, chocolate curls, or mint leaves.
