Prep your crust: Crush chocolate cookies into fine crumbs (you can do this by hand or with a food processor for less mess). Stir in melted butter until every crumb glistens. Firmly press the mixture into your pie dish, spreading up the sides for a sturdy crust. Chill to set so it won’t get soggy later.

Melt and blend chocolate: In a saucepan over gentle heat, melt your chopped chocolate with butter, stirring constantly. You want it smooth, glossy, and just starting to smell intoxicatingly rich. Take off the heat, whisk in whiskey, cocoa powder, vanilla, and a pinch of salt. Let it cool a bit before adding eggs—it shouldn’t feel hot to the touch.

Build your filling: In a big bowl, beat eggs, brown sugar, sugar, and more cocoa powder until combined and a little thickened. Slowly mix in your cooled chocolate mixture, watching the batter turn extra shiny. Pour everything into your chilled crust, then bake until the filling is just set but still has a faint wobble in the center (keep an eye out for that irresistible chocolate aroma).

Prepare the coffee custard: In a clean saucepan, whisk together cornstarch, espresso powder, sugar, salt, and milk. Heat over medium, whisking so nothing sticks. You’ll know it’s ready when it thickens and coats your spoon. Off the heat, swiftly whisk in egg yolks, then add melted chocolate and vanilla for unbeatable depth. Let cool before pouring.

Layer on the magic: Pour your cooled coffee custard over the baked chocolate layer. Smooth the top with a spatula, ensuring no gaps. Chill until fully set—the pie should hold a clean slice but feel silky when pressed lightly.

Whip the Irish cream topping: In a cold bowl, whip cream with powdered sugar and Irish cream until soft peaks form—it should billow but still be spoonable. Heap generously over your pie, swirling with the back of a spoon (sneak a taste—you’ve earned it!).

Final touch: For that bakery finish, you might sprinkle a little extra cocoa or chocolate shavings on top. Slice with a warm knife for the cleanest edges, and listen for the happy silence that follows each first bite.
