Use a blender or food processor to chop the cookies
Add the cream cheese and blend together until a thick paste is formed
In between 2 sheets of wax paper, roll half of the cookie dough into a 9 inch circle to fit into the bottom of the pan
To catch any melting ice cream, place your spring form pan onto a thin baking sheet that will fit into your freezer
Peel off the top layer of wax paper and set aside, invert the cookie layer and push down onto the bottom of the pan
Add a thick layer of ice cream to the cookie mixture (I used the whole container)
Take out the rest of the cookie mixture and place it inbetween wax paper sheets
Roll it out into a 9 in. circle
Lift the wax paper up and invert it over the ice cream layer releasing the layer of cookie over the top
Add the softened frozen whipped topping to the top and spread out
Freeze for 4-6 hours or until frozen through
Open the spring foam pan and remove it
Slice and serve with optional toppings
