Well, have eaten it now. It was fab! I made a sauce from dulce de leche, cream and Baileys, and drizzled it around a mini cheesecake made in an egg ring, with a choc chip cookie base and the Baileys mix - no whiskey though. Absolutely gorgeous, can't recommend enough, please make this pud, it's fab!
(made a kiddie's version including the Baileys but plopping some maltesers in, and topping with crushed maltesters. DH and I had the pud without the maltesers but with the Baileys sauce.}
