Happy World Nutella Day! This recipe requiring only two ingredients is a terrific way to celebrate, even if you’re only just finding out about the, umm, holiday now. Simply heat up some milk, stir in Nutella and sip away at the easiest hot chocolate you’ve ever made that didn’t come out of a packet. For added indulgence, melt in up to a tablespoon of chocolate chips or chopped up dark chocolate, and top with marshmallows. A great nightcap that the whole family can enjoy!
