Today we have a plant-based milk showdown!
Flax milk is a strong choice that, like oat milk, has no major allergens in it! It boasts a great flavor as well, and represents seed milks well!
Oat milk, on the other hand, is a popular dairy-alternative that’s been around for quite a while! People love it for its creamy texture and mild, but sweet flavor profile.

Well, we’re going to have to take a look at several things to figure that out, including their flavors, textures, nutritional profiles, dietary versatility, and more! That way, we can see them side-by-side and ultimately uncover which one is best!

Let’s begin!
