Ingredients
Method
- Step 1 – Preheat and Prep
Preheat the oven to 180°C / 350°F (160°C fan-forced). Cut a piece of parchment paper to fit your pie dish to prevent a skin forming on the custard later. - Step 2 – Make the Oreo Crust
Crush Oreos in a food processor (or ziplock bag with rolling pin) until fine crumbs form. Add melted butter and mix until it resembles damp sand. Press evenly into a 23cm (9-inch) pie dish, covering the base and sides. Bake for 10 minutes, then press down gently if puffed. Cool completely. - Step 3 – Prepare the Chocolate Filling
Whisk cornstarch, sugar, and salt in a large saucepan. Gradually whisk in milk, cream, and egg yolks until smooth. Cook over medium-high heat, whisking until steaming (3–5 minutes), then reduce to medium-low and whisk constantly until thickened and glossy. Remove from heat; stir in butter, chopped chocolates, and vanilla until melted and smooth. If needed, strain to remove lumps. - Step 4 – Assemble the Pie
Pour hot chocolate filling into the cooled crust, smoothing the top. Place the parchment directly on the custard surface to prevent a skin. Cool for 2 hours at room temperature, then refrigerate for at least 12 hours (overnight preferred) until fully set. - Step 5 – Whip the Cream & Serve
Whip cold cream, sugar, and vanilla together for 2–3 minutes until soft peaks form. Remove parchment from pie, spread or pipe whipped cream over top, and garnish with chocolate shavings. Slice and serve chilled.
Notes
Serving: Best served cold with coffee or ice cream.
Make-Ahead: Prepare up to 2 days in advance; add whipped cream before serving.
Storage: Keep covered in the fridge up to 4 days.
Freezing: Not recommended — custard may lose texture.
Tip: Use both dark and milk chocolate for the best flavor balance and always whisk cornstarch into cold liquid to avoid clumping.
