1. Prepare the Pie Crust:
- Preheat your oven to 375°F (190°C).
- On a floured surface, roll out the basic pie dough to fit a 9-inch pie dish.
- Place the dough in the pie dish, trim the edges, and crimp the sides.
- Line the crust with parchment paper and add pie weights or dried beans. Bake for 10 minutes, remove the weights, and bake for another 5-7 minutes until golden brown.
- Let the pie crust cool completely.
2. Make the Chocolate Filling:
- In a medium saucepan, combine cocoa powder, salt, 1/2 cup of heavy cream, and chopped milk chocolate. Heat over medium heat, stirring constantly, until the chocolate is melted and smooth.
- Remove from heat and stir in sugar and vanilla extract. Let the mixture cool to room temperature.
- Once cooled, fold in the marshmallow cream until well combined.
3. Whip the Remaining Cream:
- In a separate bowl, whip the remaining 1/2 cup of heavy cream until stiff peaks form.
- Gently fold the whipped cream into the chocolate mixture until smooth and light.
4. Assemble the Pie:
- Pour the chocolate mousse filling into the cooled pie crust, spreading it out evenly.
- Refrigerate the pie for at least 4 hours, or overnight, until set and firm.
5. Garnish and Serve:
- Before serving, top the pie with chocolate curls and marshmallow bits for a festive, indulgent touch.
6. Serve:
