Make Your Own Oat Milk

Jump to Recipe

It's incredibly easy to make your own oat milk! You'll save yourself a lot of money, too! I don't soak the oats or strain the "milk." Just blend up oats and water with any desired extra flavour, and this dairy free milk is good to go in a couple of minutes!

Homemade oat milk is a great non dairy alternative because of it's mild, neutral flavour. Even with certified gluten free oats, it's much less expensive to make than nut milks.

Now, I don't use this "milk" for cooking or even in coffee, because - you know what happens to oats and water when you heat it - it thickens! However, for putting on my cereal, usually oat-based anyway, it's fantastic! It also works well in smoothies.

Oat Milk Ingredients

Oats - This recipe was tested with quick oats, which are finer than regular oats. If your oat milk needs to be gluten free, be sure to use certified gluten free oats. I talk more about this on my Start Here page.

Salt - Coarse sea salt is really nice here, but feel free to use whatever you have on hand.

Instructions

Basic Oat Milk

For basic creamy oat milk, simply fill your blender jar with water to the 4-cup mark. Add 1 cup of regular oats and a pinch of sea salt. Give it a whirl at high speed for 30 seconds, and it's ready to enjoy! I use a Blendtec blender, and that works well for me.
