Let joy be unconfined. This is one of the most irresistible puddings I think I have ever made, and I did it by no more than some fruitful scimmaging about my cupboards. I long for it almost constantly, and it is not good that it is so easy to make, not good at all. If you don't run to Frangelico yourself- and there is no reason why you should- then simply replace this hazelnut sticky liqueur with some rum. Incidentally, I love this as much when made with sweetened chestnut puree (though it's so strong you could use much less) in place of the Nutella. In which case, I definitely use rum, and forgo the chopped hazelnuts, dotting with either a few crumbled marrons glaces as a special treat, or some chocolate sprinkles.
