Crush the cookies into fine crumbs. I used food processor.

Add melted butter to cookie crumb mixture. Mix well.

Place mixture into 8x8 pan sprayed with non stick cooking spray.

Sprinkle with chocolate chips evenly over crust.

Sprinkle toffee chips evenly over chips.

Sprinkle white chocolate chips over all and press mixture down to set in crust slightly.

Sprinkle with chopped nuts.

Pour half a can of sweetened condensed milk evenly over the layers.

Bake at 350°F until bubbly and slightly brown but not to dark.

Cool completely before cutting into squares. These are rich so I cut into 1 - 2 inch squares.

May use graham crackers in place of cookies and add coconut if desired.
