Heat oven to 350.
Spray pie plate with cooking spray and press 2/3 of the dough around the bottom and sides of pie plate.
Bake for 5-7 minutes.
Add chocolate chips over the dough.
Next add peanut butter cups (chopped into chunks or left whole - we broke them up into chunks.)
Then sprinkle marshmallows over the chocolate chips.
Press remaining dough into 2" flat pieces and cover pie.
Bake for an additional 15 - 17 minutes, until lightly browned.
Cool 15 minutes and drizzle with hot fudge before serving.
