Oat milk is one of my favorite dairy free milks to put in coffee, whether my coffee with oat milk is hot or iced.

Cold brew coffee with oat milk makes a great iced coffee, so feel free to use cold brew coffee in this recipe.

If you enjoy this iced coffee with oat milk, you may also enjoy my iced coffee with almond milk, which can also be made with cold brew coffee.

Cold brew coffee with almond milk tastes good hot or cold, just like coffee with oat milk does.

Choosing your Brand

I have tried a handful of oat milk brands and I can tell you, not all oat milks are created equal.

Some brands taste like oats and have the consistency of water. Other brands have a milder taste and are slightly reminiscent of milk. Oatly and Alpro are my two go-to brands.

When I visit New York, I really like Oatly, which I find to taste like regular milk and to be a little extra creamy. I’d assume this is true in Canada too.

In Israel, I only use the barista version of Oatly, which is still more watery than the regular Oatly in the States. I expect it is the same in Europe because that is where it is imported from.

For Israel and Europe, I find the Alpro oat milk indistinguishable from the Oatly Barista. However, the Alpro “Not Milk” oat milk I find to be almost identical to milk but a little sweeter – which I like.

Does iced coffee have dairy?

Typically, iced coffee does have dairy in it because it is usually made using milk.

Is oat milk good in iced coffee?

It is actually my preferred dairy free milk for iced coffee because it works so well.

What does oat milk taste like in iced coffee?

That depends on the brand you use.

Some brands taste just like regular milk, whereas others make your coffee taste a little like oatmeal.

What can I use in place of maple syrup?

Maple syrup adds a nice flavor to this drink. However, if you don’t want it or don’t have it on hand, you can replace it with simple syrup.
