In terms of making this chocolate milk ice cream, quite a lot, actually. Generally speaking, oat milk is the perfect choice for making ice cream for a few reasons.  First, it's typically creamier than rice milk, creating a velvety smooth ice cream texture that makes every bite heavenly. Plus, oat milk has more fat than rice milk, which is definitely what we want here. Plus, the natural sweetness of oat milk blends perfectly with the cocoa and chocolate, resulting in an extra sweet and delicious treat. Lastly, oat milk is more easily accessible than rice milk, so it seems like a win-win-win to me!
