If you are making a dessert for St. Patrick's Day, it should probably have Baileys in it. This cheesecake is rich, creamy, and just boozy enough to know it's there - set on a deeply chocolatey Oreo crust that holds its shape perfectly and tastes like it came from somewhere far fancier than your own kitchen. It also happens to be one of the more crowd-pleasing things you can show up with to any gathering, holiday or not.
