Chocolate Crust

1. Stir together the ground cookies and melted butter. Press into a deep 9” pie dish and place in the refrigerator. 

Chocolate Pie Filling

1. In a large bowl, add half the jar of fluff, butter, and chocolate in that order so that the fluff is at the bottom of the bowl. 
2. In a medium saucepan, add 2 cups of heavy cream and place over medium heat. Heat just until it starts to steam, about 5 minutes. Do not bubble. 
3. Pour over the bowl of chocolate and let it sit for a couple minutes. Then whisk until smooth. The marshmallow will appear clumpy at first, but keep whisking and it will slowly break up and dissolve into the chocolate.
4. Pour the filling through a fine mesh sieve and into the crust. If you have any filling that won’t fit, pour into a container and chill for a nice little snack!
5. Tap the pan a couple times to release any air bubbles and carefully transfer to the refrigerator to chill overnight. If this transfer feels a little too risky, I like to let the pie rest at room temperature for about an hour to thicken so that it’s easier to carry to the fridge. 
6. Now make the whipped cream. In a large bowl using a hand or stand mixer with the whisk attachment, whip the remaining 1 cup of cream on high speed until it JUST starts to thicken. Then scoop in the remaining fluff and whip until thickened, about 1 minute. 
7. Scoop the whipped cream into a container and chill overnight as well. 
8. To serve, you can dish out the slices when the pie is fresh from the refrigerator or has been sitting out to room temp. But if you want a restaurant-quality slice, preheat your oven to the lowest temperature possible. Once preheated, turn the oven off and place the chilled pie inside. Leave it there for about 15 minutes.
9. Then remove it from the oven and run a large knife under hot water. Wipe it dry and slice into the pie, running the knife under hot water for each cut. 
10. Dollop the slice with a good scoop of whipped cream and shave some chocolate on top from that reserved dark chocolate square. Now dig in!
