The milk and snow mixture is your base, and you can add whatever you’d like from there. You can keep it simple and just add a bit of vanilla extract, or you can add lots of mix-ins and flavorings. We had bananas that were getting overripe, so we mashed them with a fork and stirred them in with almond extract and slivered almonds. In my daughter’s bowl, I also added a few chocolate chips and some sprinkles for fun. I imagine it would also be good with peanut butter, candy chunks or chopped up candy bars. Be aware that it is pretty runny though, so mix-ins like chocolate syrup will make it even less solid.
