Process Oreo cookies in a food processor until finely crushed. Add melted butter and pulse until the mixture resembles damp sand.

Press about two-thirds of the crumb mixture firmly along the sides of a 23 cm deep-dish pie plate. Use the remaining mixture to cover the bottom, pressing evenly to create a sturdy base. Set aside.

Using a stand mixer with a whisk attachment or hand beaters, whip cold heavy cream, powdered sugar, and instant espresso powder on high speed until stiff peaks form, approximately 6–7 minutes.

Reduce to low speed and incorporate sweetened condensed milk. Mix for 30 seconds, scrape the bowl, then mix another 30 seconds until just combined. Do not overwhip to maintain a light texture.

Transfer the coffee cream filling into the prepared Oreo crust. Smooth the surface with a spatula, creating decorative swirls if desired. Freeze uncovered for a minimum of 6 hours until completely set.

Once fully frozen, cover the pie with plastic wrap and, optionally, a layer of foil for long-term storage.

Allow the pie to rest at room temperature for approximately 10 minutes before slicing. Serve frozen.
