1-Step 1: Prepare the Crust Preheat the oven to 350 degrees Fahrenheit and crush 24 whole chocolate sandwich cookies into fine crumbs using a food processor. Mix the crumbs with 5 tablespoons of melted butter until it sticks together well. Press this mixture firmly into a 9-inch pie dish to cover the bottom and sides, then bake for 10 to 12 minutes. Let it cool completely before moving on, as this helps avoid issues like a soggy base.

2-Step 2: Make the Filling For the chocolate pudding filling, combine 1/3 cup sugar and 2 1/2 cups whole milk in a saucepan over medium heat until it just simmers. In another bowl, whisk 6 large egg yolks with 2 tablespoons cornstarch until smooth. Slowly add a few spoonfuls of the hot milk mixture to the egg yolks, whisking constantly to temper them. Pour the egg mixture back into the saucepan and whisk over medium heat until it thickens and bubbles gently. Remove from heat and stir in 6 tablespoons of chopped unsalted butter, 8 ounces of chopped semi-sweet chocolate, and 1 1/2 teaspoons vanilla extract until everything blends into a smooth, creamy texture. This part creates the signature smooth filling that defines a great chocolate cream pie. For more ideas on fillings, check out our simple dessert recipes page.

3-Step 3: Assemble and Chill Pour the hot filling into the cooled crust and spread it evenly. Cover with plastic wrap pressed directly on the surface to prevent a skin from forming, then refrigerate for at least 4 to 6 hours or overnight. This chilling time is crucial for setting that smooth filling, making it easier to cut nice slices.

4-Step 4: Add the Topping Whip 1 cup heavy cream with 2 tablespoons powdered sugar or granulated sugar and 1 1/2 teaspoons vanilla extract until soft peaks form. Spread this over the set pudding and garnish with chocolate shavings for a finishing touch. The total preparation time is about 6 hours and 20 minutes, including active cooking and chilling, but you can prepare the crust 1 to 2 days ahead to save time.
