This no bake Irish Cream Oreo Ice Box Cake is likely one of the easiest desserts you'll ever make and absolutely perfect to enjoy for St. Patrick's Day.
In the bowl of an electric mixer, add heavy cream, mascarpone, sugar, vanilla and Irish cream.
Using a whisk attachment, mix on low speed until just combined and then mix on medium speed until it becomes thick and forms peaks.
In an 8″ springform pan, place a single layer of Oreo cookies.
Carefully cover cookies with 1/4 of the whipped cream mixture, smoothing into a flat layer with a rubber spatula.
Repeat Oreo and whipped cream layers three additional times so that you have a total of four layers of cookies and four layers of whipped cream, ending with a whipped cream layer.
Place plastic wrap directly on top of final layer of cream and refrigerate overnight.
Before serving, garnish with additional Oreo cookies and dark chocolate curls, if desired.
Notes
TIP: To make this Oreo icebox cake family friendly, simply omit the Irish cream or substitute Irish cream flavored coffee creamer.TIP: To insure your kitchen isn't bathed in cream, be sure to start the speed slowly until the mixture is combined!TIP: Smoothing the whipped cream layer carefully will insure the Oreos underneath will not shift so that the layers of your cake will remain distinct.
