Let’s break down the process into easy-to-follow steps. I’ll guide you through each stage.

Make the Pie:

Step 1: Prepare Pudding Filling. In a large bowl, whisk together the milk, Baileys Irish Cream, and instant chocolate pudding mix until well combined. Let the pudding thicken for 5 minutes.

Step 2: Assemble the Pie. Spread half of the pudding into the prepared Oreo pie crust in an even layer. Top with the crushed Oreo crumbs and mini chocolate chips. Gently spread the remaining pudding over the top.

Step 3: Chill. Cover the pan with a layer of plastic wrap (to prevent a skin from forming on the pudding) and refrigerate for at least 8 hours, or up to overnight. This allows the filling to set completely.

Make the Whipped Cream & Assembly:

Step 1: Whip Cream. In a large bowl, using a handheld mixer or a stand mixer fitted with the whisk attachment, whip the heavy cream until soft peaks form, about 2 minutes.

Step 2: Add Sugar and Baileys. Add the granulated sugar and Baileys (or vanilla extract) and whip until the mixture is thickened and creamy, about 1 minute (it should hold its shape when you lift the mixer up).

Step 3: Top and Decorate. Dollop the whipped cream onto the chilled pie (be sure to use all of it!). Top with desired toppings (mini chocolate chips, chocolate shavings, crushed Oreos, cocoa powder, or sprinkles), if using.

These instructions are very simpl
