Let the ice cream sit out for a little bit to soften. Once softened, scoop into pie crust and spread evenly. If you use the Dreyer's ice cream I used you'll use almost the whole carton. Top with crushed Oreo cookies.

Then top with the prepared chocolate sauce. Cover and place in your freezer. Remove from freezer 10 minutes before serving. Top each serving with sweetened whipped cream.

For the chocolate sauce - mix all ingredients in a sauce pan. Cook over medium and bring to a boil. Boil for 1 minute and remove from stove. Allow to cool. You will have a little more than you need for the pie (about 1/4 to 1/3 cup), but just save it and use it to a bowl of ice cream another day.
