Method
- Place the Oreo cookies — filling and all — into a food processor and pulse until you have fine, even crumbs with no large chunks remaining. Alternatively, seal them in a zip-lock bag and crush with a rolling pin.
- Transfer the crumbs to a large bowl. Pour the melted butter over them and add the pinch of salt. Stir until every crumb is moistened and the mixture holds together when pressed between your fingers. Press the mixture firmly and evenly into the bottom and up the sides of a 9-inch pie dish using the flat bottom of a measuring cup or glass. Refrigerate for at least 20 minutes.
- Using a sharp heavy knife, chop the chocolate bar into very small, roughly even pieces — aim for nothing larger than a pea. Fine chopping ensures fast, even melting and a perfectly smooth ganache filling.
- Pour the heavy cream into a medium saucepan and add the sugar (if using) and espresso powder. Heat over medium heat, stirring occasionally, until the cream just reaches a simmer with small bubbles forming around the edges and gentle steam rising. Do not boil.
- Place the finely chopped chocolate in a large heatproof bowl. Pour the hot cream directly over the chocolate. Let it sit completely undisturbed for 2 full minutes. Add the room temperature butter pieces and vanilla extract, then stir slowly from the center outward in steady circles until the ganache is completely smooth, glossy, and uniform. Add the fine sea salt and stir once more.
- Remove the chilled crust from the refrigerator. Pour the warm ganache filling into the crust in a slow, steady stream starting from the center, letting it spread naturally outward. Tap the pie dish gently on the counter two or three times to release any air bubbles and level the surface.
- Let the pie sit at room temperature for 20 minutes, then transfer it to the refrigerator. Chill uncovered for at least 4 hours, or ideally overnight. Do not cover until fully set to prevent condensation forming on the surface.
- Once fully set, scatter flaky sea salt over the top. Add fresh raspberries, a dusting of cocoa powder, or chocolate shavings. To slice cleanly, run a sharp knife under hot water, wipe it dry, and cut with a single downward press — no sawing. Repeat between each slice. Add a dollop of lightly sweetened whipped cream to each slice before serving.
Notes
Pro Tips: Always use high-quality dark chocolate bar (60–70% cacao) — never chocolate chips, which contain stabilizers that prevent smooth melting. Keep your butter at room temperature before adding it to the ganache so it emulsifies seamlessly and creates that signature truffle gloss. Add 1 tablespoon of espresso powder to the cream — it intensifies the chocolate flavor without tasting like coffee. Press the Oreo crust firmly using the flat bottom of a glass for clean slices that hold together. Let the pie chill overnight if possible — the texture and flavor peak at the 24-hour mark. Pull the pie from the refrigerator 15–20 minutes before serving for that perfect melt-on-contact truffle consistency. To slice cleanly, run your knife under hot water and wipe dry between every single cut.
