There are so many delicious types of milks out there that have different flavors, textures, allergens, nutritional benefits, and more!
Today we’re going to compare one of the most popular flavors with one of the most popular plant-based milks: vanilla milk versus oat milk!
Vanilla milk is basically any type of milk with vanilla flavoring added, creating a unique (and delicious) twist on some already great milks! Oat milk, on the other hand, is popular for a reason – it’s tasty, allergen-free, and boasts some great nutritional qualities!
If you’re having a tough time deciding between these two or just want to see how they compare, you’re in luck! We’ll check these out side-by-side, determining what things one does better than the other.

Let’s jump in!
Comparing vanilla milk vs oat milk
Vanilla milk can really be any type of milk, animal or plant-based, with vanilla flavoring added. That means its characteristics can greatly vary, including whether or not it’s suitable for vegan, keto, or paleo diets.
Oat milk, on the other hand, is plant-based. It has no allergens at all, and is a great choice for vegan diets! However, it’s not suitable for paleo or keto diets, so check out something like almond milk if you want that!

Differences between vanilla milk and oat milk
The main difference between vanilla milk and oat milk is how they taste, with potential differences in their sources as well.
Vanilla milk is basically any type of milk with the vanilla flavor added, which can be done by using vanilla beans, flavorings, or vanilla extract.
That means you can take something like regular milk (or even oat milk), add some vanilla flavoring, and boom, you have vanilla milk!
Oat milk has a mild flavor that’s slightly sweet, and it’s made by blending oats and water together. It sometimes has added sweeteners or flavorings (like vanilla extract) added to enhance its taste and texture, and often contains added guar gum, vitamins, and minerals to further boost the overall milk.
It’s also really easy to make oat milk at home!

Can you substitute vanilla milk for oat milk?
In most cases, you can absolutely substitute these out for one another! Now, it gets a little tricky if you have allergy requirements or are following special diets as vanilla milk can come from basically any type of milk! This changes many factors about it, along with its texture and flavor profile – it’ll always taste like vanilla, but regular milk with vanilla added will taste and feel different than oat milk with vanilla added, for example.
Plus, vanilla milk tends to be a lot sweeter than oat milk, which may not be suitable for certain dishes.
Nutrition: Vanilla milk vs oat milk
Vanilla milk’s nutritional profile really varies depending on what type of milk it’s made from. However, it tends to have added sugar in – although there are unsweetened vanilla versions for some milks!

Oat milk’s calcium and vitamin D contents are quite decent!

Oat milk can be stored at room temperature, preferably in a cool and dry place, however. It’s good for 1-4 months if it’s in an aseptic carton, but put it in the fridge and use it up within 7-10 days after opening.
