Chocolate Peanut Butter Of course, this is my favourite flavour! This KOS Chocolate Peanut Butter ($30 for 15 servings) tastes so good on its own, so it's perfect when I just want to mix up a quick shake to get some extra protein. It's also really delicious as a vegan nice cream made with frozen banana.
