Creating Mississippi Mud Pie is a rewarding process. Follow these steps to make your own delicious pie:

1. Preheat the Oven: Set your oven to 350°F (175°C).
2. Prepare the Crust: In a mixing bowl, combine chocolate wafer crumbs, melted butter, and sugar. Mix until well combined.
3. Form the Crust: Press the mixture firmly into the bottom and up the sides of a 9-inch pie pan. Bake for 10 minutes, then remove from the oven and allow to cool.
4. Melt the Chocolate: In a small saucepan over low heat, combine the semi-sweet chocolate chips and heavy cream. Stir until melted and smooth, then remove from heat.
5. Mix the Filling: In a large bowl, whisk together the eggs, sugar, vanilla extract, and salt until well combined. Slowly add the melted chocolate mixture, stirring constantly to prevent cooking the eggs.
6. Fill the Crust: Pour the chocolate filling into the cooled crust, spreading it evenly.
7. Bake the Pie: Bake the pie in the preheated oven for 25-30 minutes, or until the filling is set but still slightly jiggly in the center.
8. Cool the Pie: Remove from the oven and let the pie cool to room temperature. Refrigerate for at least 2 hours before serving.
9. Prepare the Topping: Once chilled, spread whipped cream over the top of the pie. If desired, add mini marshmallows and chopped nuts.
10. Garnish: Finish with chocolate shavings for an extra touch of elegance.

Following these steps will lead you to a wonderful Mississippi Mud Pie that is sure to delight!
