If you want to prepare Oreo layer and topping, start by spraying an 8 x 8 inch or 9 x 9 inch square pan with non stick spray and then set it aside. 

Next, put Oreo cookies in the food processor and pulse until you get crumbs. Use a medium dish, to combine Oreo crumbs and melted butter then press ½ of the mixture at the bottom of an 8 x 8 or 9 x 9 inch square pan. Save the remaining crumbs for later.

Meanwhile, beat cream cheese and powdered sugar until it gets smooth, then add heavy whipping cream, mint extract and green food  coloring and beat some more, until stiff peaks form.

Add sweetened condensed milk and continue beating until it´s well combined then fold in chocolate chips.

Spread the mixture over the Oreo layer and sprinkle with the remaining Oreo crumbs.
