Preheat oven to 325F.

Stir together graham crackers with butter and press into a greased 9″ pie pan.

In a medium saucepan, whisk together cream and milk. Warm over medium low heat. Add in chocolate and stir until chocolate has been completely melted and is smooth. Slowly add in vanilla and whisked eggs, and whisk until smooth.

Pour chocolate filling into baked pie crust. Bake for 15-20 minutes, or until chocolate filling is set and does not jiggle when shook. Remove from oven.

Cut marshmallows in half and place flat side down on top of pie until covered.

Lower oven rack to the middle position and set oven to the lowest broil setting. Place pie on the rack and lightly toast the marshmallows. Remove the second you see brown!

Chill for a couple of hours or can be served slightly warm.
