Creamy, slightly sweet, absolutely delicious — oat milk is all the rage right now and I’m not mad about it. In fact, I’ve been using oat milk in everything from coffee to cereal to baking and it has quickly become one of my favorite dairy free milks out there. I’m currently going dairy free while I breastfeed Viggo so it’s amazing to have such a delicious dairy free alternative that I can add to literally everything.

If you haven’t tried making your own oat milk from scratch, today is the day! It’s SO EASY and more affordable than any store-bought brand. Bonus: you don’t have to spend time soaking nuts like you would with homemade nut milk! We’ve included everything you need to know about how to make oat milk, plus plenty of tips, flavor add-ins (yum) and plenty of ways to use it.

Be sure to check out this video tutorial, too, and get ready to have delicious oat milk in under 5 minutes.

The two key ingredients in homemade oat milk

The best part about making oat milk at home is that you know exactly what’s going into it. This easy homemade oat milk recipe has no weird additives but is equally as delicious as the store-bought version. Here’s what you’ll need to make it:

  • Oats: we’re using old fashion rolled oats in this oat milk recipe. Feel free to use certified gluten free rolled oats!
  • Water: the second key ingredient in homemade oat milk is water! This will help blend up the oats to make creamy oat milk.

How to make homemade oat milk

Making your own oat milk can seem intimidating, but it’s much easier than you think and SO affordable!

  1. Blend your ingredients. You’ll first add the rolled oats and water to a blender and blend on high for just 5-8 seconds.
  2. Strain it. Next, be sure to strain the blended mixture into a large glass or jar over a wire mesh sieve or with a clean dish towel. Use a spoon to stir it around so that you get all of the liquid out. Don’t discard the oat pulp — we have easy ways to use it below!
  3. Store & enjoy. Feel free to use the oat milk immediately or store it in the fridge.

Tips for making creamy oat milk

Don’t forget these simple tips and tricks for getting perfect oat milk every time:

  • Don’t soak your oats. Unlike homemade nut milk, you’ll want to be sure you do not let the rolled oats soak in the water before blending them. This can make the oat milk slimy.
  • Be sure not to over blend. Over blending the oats and water together can also create a slimy texture in the oat milk. Just give the oats and water a quick blend on high so they’re combined.
  • Do not use steel cut oats. Rolled oats are truly the way to go when making homemade oat milk perfectly creamy.

Can I heat it up?

I wouldn’t recommend heating this oat milk on its own, or it could congeal. Feel free to add it to hot coffee or tea, though!

Save that leftover oat pulp!

That’s right, you can actually use the oat “pulp” that’s left over after you squeeze the oat milk into a jar or glass. Feel free to add this pulp to your regular bowl of oatmeal or even overnight oats.

How to store fresh oat milk

Store your homemade oat milk in an airtight jar or container in the refrigerator for up to 5 days.
