Crush Oreos and put into a medium bowl. Mix in melted butter. Pat evenly into 9 x 13 pan to make the crust.
Soften ice cream enough to spread over Oreo crust.
Place in freezer until ice cream firms up.
Spread Cool Whip over the caramel & sprinkle with chopped Snickers. Drizzle with caramel topping.
Freeze for at least a couple hours to firm up & then enjoy!
