To a third of the marshmallows, I combined praline paste (made by grinding hazelnuts and almonds into a paste that has a consistency similar to that of peanut butter), toasted and chopped hazelnuts, and the crispy puffed-rice cereal. Those nutty, creamy sensations didn't make it to the end of the day. To another third, I added melted chocolate, a dash (or two) of bourbon, and chopped, toasted pecans along with the requisite cereal. Let's just say those boozy, chocolate-filled treats didn't even get a chance to cool. The final third I made with a generous splash of vanilla…for old times' sake.
