Preheat oven to 350°F.
Add the Oreo cookies to the bowl of a food processor and process until they become fine crumbs. Pour into a bowl and stir in the butter and pinch of salt.
30 mint Oreo sandwich cookies, 4 tablespoons unsalted butter, ⅛ teaspoon kosher salt
Using medium pressure, press the crust into the bottom and sides of a 9- or 10-inch pie dish. Use your hand or the back of a measuring cup to form one even layer.
Bake for 10 minutes. Set on a wire rack to cool completely while you make the filling.
In the bowl of a stand mixer fitted with a whisk attachment, whip the 1½ cups of cream to stiff peaks. Transfer from the mixer bowl into a medium bowl and place in the fridge to chill while you prepare the rest of the filling.
1½ cups heavy whipping cream
In the mixer bowl (no need to clean it) beat the cream cheese on medium-high speed until smooth. Scrape down the sides and bottom of the bowl as needed.
16 ounces cream cheese
With the mixer off, add in the powdered sugar. Mix on low speed until combined. Increase to medium-high speed and mix until completely smooth. Scrape down the sides as needed. If there are any lumps of cream cheese, keep mixing!
1⅓ cups powdered sugar
Add in the Crème De Menthe, Crème De Cacao, and food coloring. Mix on medium until combined.
¼ cup Crème de Menthe liqueur, 3 tablespoons Crème de Cacao liqueur, 1-2 drops green food coloring
With a rubber spatula, gently fold in the whipped cream until combined.
Scoop the filling into the crust and smooth it into an even layer.
Cover and refrigerate for at least 4 hours.
When ready to serve, beat the remaining heavy cream, powdered sugar, and vanilla until stiff peaks form. Spoon or pipe the cream onto the pie. Top with crushed cookies. Serve and enjoy.
