Homemade Oat Milk

Jump to Recipe

I've been on an oat milk kick for a while now. You'll see it in my smoothies, in my matcha lattes, in my oatmeal etc... so how about a homemade oat milk recipe so you can make it at home anytime you need a refill!

Homemade Oat Milk couldn't be easier! Similar to making a homemade nut milk at home, oat milk just takes a few pantry staple ingredients, a little bit of soaking time, and voila... done! It's great to use in any number of recipes that call for any kind of milk. Baking, fair game. Coffee and Matcha drinks, you know it. Adding it into overnight oatmeal, why not. You get the idea. Anytime a recipe calls for milk, this is a great option and it is super clean without any weird add-ins.

The recipe below calls for Old Fashioned Oats (might be seen as Rolled Oats). I keep them stocked for this recipe, my dad's kitchen sink cookies etc... and these are the ones I keep on hand.

A few of my favorite recipes that use homemade oat milk:

  1. I was just wondering how easy it would be to make my own last night because I wanted a lavender latte but had no oat milk. Thanks so much for this!

    1. so oat milk doesnt froth great in my opinion unless its the barista blend that you buy from the store that has some additive to help frothing! So no, it wont froth like regular milk

  2. I had no idea it was so easy to make oat milk. Mine came out great! Any suggestions for using the oats left over after straining? I hate to just throw them out.
