Crush the Oreo cookies in a food processor or by placing the cookies in a ziploc bag and bashing them with a rolling pin.
Place the crushed cookies in a bowl and stir together with the melted butter.
Press the mixture into the bottom and up the sides of a 9-inch pie plate. Place in the fridge as you make the filling.

Chop the chocolate into very, very small pieces.
Add the butter, chopped chocolate, mini marshmallows and water to a large heavy bottom saucepan.
Turn the burner to low heat and gently stir as the mixture starts to melt. Be very careful that the chocolate doesn't burn.
Once completely melted, remove from the heat. Whisk vigorously if the butter seems to be separating.
In a separate large bowl, beat the heavy cream until stiff peaks form.
Gently fold the whipped cream into the cooled chocolate mixture using a rubber spatula until the mixture is no longer streaky. Go gently to keep the volume from the whipped cream.
Spoon the chocolate mousse filling into the pie plate and smooth the top. Cover the top of the pie plate, and place in the fridge to set for at least 4 hours.

When ready to serve, remove the pie from the fridge.
In a large bowl, beat the whipped cream until soft peaks form.
Spoon the whipped cream on top of the pie and (optionally) sprinkle the top with chocolate shavings.
Slice the pie with a thin, sharp knife - such as a paring knife (do not use a table knife) being sure to cut all the way through the crust.

Semi-sweet chocolate can be used for a sweeter pie. Make sure to use high-quality baking chocolate and not chocolate chips.
To make chocolate shavings, use a paring knife to brush chocolate shavings off of a chocolate bar. Always move the knife away from you.
Store leftovers covered in the fridge for up to 4 days. Pie can be easily made 1 day in advance.
Nutrition information is based on 1 piece, assuming the pie is cut into 10 equal pieces. You only need a very small sliver of the pie, as it is very rich.
