Preheat the Oven: Begin by setting your oven temperature to 350°F (175°C) to ensure it’s ready for baking.
Prepare the Chocolate Filling: In a medium saucepan set over low heat, combine the heavy cream and milk chocolate chips. Stir constantly with a spatula until the chocolate is completely melted and the mixture is smooth. Once all the chocolate has melted, remove the saucepan from the heat to prevent scorching.
Mix the Base: In a large mixing bowl, whisk together the granulated sugar, eggs, and vanilla extract until the mixture is well combined and slightly frothy. Gradually pour the warm melted chocolate mixture into the egg mixture, stirring continuously until fully blended and homogenous.
Pour into Crust: Carefully pour the luscious chocolate filling into the prepared graham cracker pie crust, using a spatula to spread and smooth the surface evenly.
Bake the Pie: Place the pie in your preheated oven and bake for 25-30 minutes. You're looking for the filling to be set around the edges but still slightly fudgy in the center.
Add Marshmallows: After baking, take the pie out of the oven and promptly sprinkle the mini marshmallows evenly over the top. Return the pie to the oven and switch to broil for 1-2 minutes, watching it closely to prevent burning, until the marshmallows turn a beautiful golden brown.
Cool Down: Allow the pie to cool at room temperature for approximately 30 minutes. This will help it firm up nicely while retaining its gooey texture.
Garnish: Once the pie has cooled, sprinkle the crushed graham crackers generously over the top for added texture, and finish it off with beautiful chocolate shavings to enhance its presentation.
Serve: Carefully slice the pie into wedges and serve it either at room temperature or chilled for a delightful treat.
Notes
For an extra dash of flair, consider serving the pie with a dollop of whipped cream on the side and a drizzle of chocolate sauce.
