Preheat oven to 375 degrees F.

Melt the chocolate, butter, and sugar together in a heavy saucepan over low heat.

Remove the pan from the heat and let cool a few minutes.

Add then the eggs and beat well.

Pour the filling into the pie crust(s). (You can make this into one thick pie or two shallow pies. It's so rich that I prefer two shallow pies!)

Bake for 25 minutes or until just set.

Serve warm or cold or in various states of frozen with your favorite toppings. (I like mine plain!)
