To crush the Oreo's simply place them in a food processor, with the filling, and blitz until you get a fine crumb. You can also place them in a gallon sized ziptop bag and crush them with a rolling pin.
You can easily swap the golden Oreos with regular or even use a graham cracker crust instead. Some think the saltiness of Ritz crackers is a delicious substitute!
You can use Cool Whip or make your own homemade whipped cream for topping. Chopped toffee, candy, or nuts are all great garnish options.
