Step 1: Prepare the Chocolate Cookie Crust

1. Preheat Oven: Preheat your oven to 350°F (175°C).
2. Combine Ingredients: In a medium bowl, mix chocolate cookie crumbs, melted butter, and sugar until the mixture is evenly combined and resembles wet sand.
3. Form the Crust: Press the mixture firmly into the bottom and up the sides of a 9-inch pie dish.
4. Bake & Cool: Bake for 10 minutes, then allow to cool completely before adding the chocolate layers.

Step 2: Make the Dark Chocolate Layer

1. Heat the Cream: In a small saucepan, heat ½ cup heavy cream over medium heat until it just begins to simmer (do not boil).
2. Melt the Chocolate: Remove from heat and stir in dark chocolate chips and vanilla extract. Stir until smooth and fully melted.
3. Pour & Chill: Pour the dark chocolate mixture into the cooled crust and spread evenly. Refrigerate for 30 minutes until set.

Step 3: Make the Milk Chocolate Layer

1. Heat the Cream: Repeat the process by heating ½ cup heavy cream until simmering.
2. Melt the Chocolate: Remove from heat and stir in milk chocolate chips and vanilla extract. Stir until smooth.
3. Pour & Chill: Pour the milk chocolate mixture over the set dark chocolate layer and refrigerate for 30 minutes.

Step 4: Make the White Chocolate Layer

1. Heat the Cream: Again, heat ½ cup heavy cream over medium heat until simmering.
2. Melt the Chocolate: Remove from heat and stir in white chocolate chips and vanilla extract. Stir until smooth.
3. Pour & Chill: Pour the white chocolate mixture over the set milk chocolate layer. Refrigerate for at least 2 hours, or until fully set.

Step 5: Garnish & Serve

1. Add Toppings: Once the pie is fully set, top with whipped cream and chocolate shavings or curls for an elegant finish.
2. Slice & Enjoy: Use a sharp, warm knife (run it under hot water and wipe dry) to cut clean slices.
