Instructions:
For the Crust:
- Place the cookies in a food processor and pulse until cookies are a fine crumb (alternatively, place the cookies in a resealable bag and smash with a rolling pin). Transfer to a medium bowl and add a large pinch of salt followed by Kerrygold Unsalted Butter, mixing to combine.
 - Transfer to a 9” pie plate or tart pan. Place in refrigerator and chill while you prepare the filling.
 
For the Filling:
- Bring Kerrygold Irish Cream, ½ the can of sweetened condensed milk and 1 cup heavy cream to a simmer in a medium pot over medium heat.
 - Whisk egg yolks and cornstarch together until no lumps remain. Slowly whisk in cream mixture to the egg yolks until everything is incorporated.
 - Pour mixture back into the pot and cook, whisking constantly, until the mixture has started to bubble and thicken considerably, 4–6 minutes.
 - Place chocolate in a large bowl. Pour thickened pastry cream over chocolate and let it sit a minute or two to melt. Whisk until all the chocolate is dissolved, then add 1 cup sour cream and a generous pinch of salt and whisk to blend.
 - Pour chocolate mixture into the prepared crust, smoothing the top. Refrigerate until completely set, at least 2 hours.
 - When ready to serve, whisk the remaining cup of heavy cream in a medium bowl until you’ve got medium-stiff peaks (the cream should stand up at the tip of the whisk). Whisk in remaining cup of sour cream and the remaining sweetened condensed milk.
 - Dollop on top of chilled chocolate pie before serving.
