Ingredients

3 cups Oreo crumbs

6 tbsp butter, melted

1½ cups heavy whipping cream, cold (divided)

½ cup powdered sugar (divided)

1 teaspoon vanilla extract

1 teaspoon espresso powder

16 oz semi-sweet chocolate, chopped

½ cup unsalted butter, melted (plus 1 tbsp for greasing the pan)

10 oz mascarpone cheese, room temperature

5 Oreo cookies (for garnish)

1 teaspoon unsweetened cocoa powder

Instructions

Step 1: Grease a 9½ inch pie pan with 1 tablespoon melted butter or baking spray. Set aside.

Step 2: In a medium bowl, combine melted butter with Oreo cookie crumbs. Mix until fully combined.

Step 3: Firmly press the Oreo crumb mixture into the bottom and up the sides of the prepared pie pan. Use a measuring cup to shape the crust evenly. Refrigerate to allow it to harden.

Step 4: In a mixer bowl, whip 1 cup heavy cream with ½ cup powdered sugar and vanilla extract on high speed until it thickens and holds its shape. Set aside.

Step 5: In a microwave-safe bowl, combine chopped chocolate, remaining ½ cup heavy cream, and melted butter. Microwave for 1 minute, stir, then microwave another minute until boiling.

Step 6: Stir in espresso powder until the chocolate mixture is smooth and shiny.

Step 7: Whisk mascarpone cheese into the chocolate mixture until fully combined and smooth.

Step 8: Gently fold the whipped cream into the chocolate mixture with a spatula until completely blended.

Step 9: Pour the chocolate filling evenly into the chilled Oreo crust.

Step 10: In a clean bowl, whip 1 cup heavy cream with remaining powdered sugar on high speed until it thickens and holds shape. Transfer to a piping bag fitted with a star tip.

Step 11: Pipe whipped cream onto the pie as decoration. Top with Oreo cookies and sprinkle with cocoa powder.

Step 12: Chill the pie in the refrigerator for 4–6 hours or overnight before serving. Enjoy!

Tips & Variations

For a stronger coffee flavor, add an extra teaspoon of espresso powder to the chocolate mixture.

Use a food processor to quickly crush the Oreo cookies for the crust.

Try decorating with chocolate shavings or fresh berries instead of Oreos for a different look.

Make sure the heavy cream is cold before whipping to achieve better volume.

FAQs

Can I use a different type of cookie for the crust?

Yes, graham crackers or chocolate wafers can be used as substitutes, but Oreos add a distinct flavor that complements the chocolate filling well.

Do I need an electric mixer to whip the cream?

An electric mixer makes whipping easier and faster, but you can also use a whisk if you have the patience. Whip until soft peaks form for best results.
