In a large bowl combine the cream cheese, powdered sugar, and whipped topping. Mix until combined. Add enough milk to slightly thin the dip.
Fold in 4 of the chopped SNICKERS® bar.
Divide the dip in to 2 bowls. Add the vanilla to one and the cocoa powder to the other. Mix each dip and then spread one into each end zone. Sprinkle with remaining chopped SNICKERS® bars.
