Becky’s Tips

Rolled, old-fashioned oats are best. Avoid quick-cooking or instant oats, which can lead to slimy oat milk. To ensure this oat milk is gluten-free, use certified gluten-free oats.
Be sure to use iced water for this recipe for the best results.
If you don’t have a large blender, you can blend it in batches in a smaller one.

Serving Suggestions

Once you’ve learned how to make oat milk, the possibilities for its use are endless. Oat milk can be used in pretty much any place you would use dairy or other vegan milks, so it’s an easy way to make healthier breakfasts. And it’s a great addition to any coffee drink you’re fond of. Just swap the milk in a 1:1 ratio. We love it in an iced chai tea latte , or dairy-free banana pancakes .

Oat milk has a fairly neutral flavor compared to other plant-based milks and it makes a great allergen-friendly alternative to dairy and nut milks.

Oat milk is lower in saturated fats and higher in fiber than traditional cow’s milk. However, it is also lower in protein. Both milks have health benefits, and neither is ‘healthier’ than the other.

A blender produces the best results, but you can make this in a food processor as well. You can make it by hand, but it is some effort, you will have to grind the oats down in a pestle and mortar until very fine, then mix with the cold water and salt.

The process of blending the oats and water produces heat, which can cause the oats to begin to cook and turn slimy. Use rolled, old-fashioned oats and super cold ice water to prevent this from happening.

We don’t recommend it, as it can thicken and congeal when heated.
