From the pie mix package, combine the chocolate crumbs with the melted oleo and press firmly in bottom and sides of pie pan. In a small bowl, blend chocolate creme filling mix and 2 1/4 C milk at lowest sped for 2 mins. Then beat 2 mins at highest speed possible until smooth. Fold in marshmallows and 3/4 C chips.Spread evenly in crust. In small bown, blend whipped topping and 1/2 C milk at low speed until moistened.Then beat 5 mins at high speed until topping forms peaks. Spread evenly over filling. Top with reserved 1/4 C chocolate chips. Chill at least 30 mins in refrig. * I would probably use cool whip instead of fussing with dream whip.
