This one goes out to all of my lactose-intolerant friends out there! If you’re not already making your own homemade oat milk, promise me you’ll try this recipe. Because they’re charging waaaaay too much for it at the store, considering how simple it is to make. It literally takes about five minutes and it tastes SO GOOD. Like, I usually feel kind of “meh” about oat milk, but I wanted to guzzle the entire batch because it was so cool, creamy, and refreshing. So promise me you’ll bookmark this page and give it a try this weekend, K?
What’s in Oat milk?
When I tell you how simple this oat milk is, you might have a little heart attack when you realize how much you’ve been paying for it at the store. Oat milk is literally just oats, water, salt, vanilla (optional), and a sweetener (optional). That’s it. Five simple ingredients! Here’s a little more detail about what I used to make my homemade oat milk:
Oats – I tested both old-fashioned rolled oats and quick oats for this recipe and old-fashioned oats were the clear winner. Old-fashioned rolled oats break down just enough when blended to yield a creamy milk that is not too thick or slimy. Quick oats are so powdery to begin with that they completely disintegrated in the water and make a thick, sludge-like oat milk. #nothanks
Water – Make sure to use cold water to make your homemade oat milk so the starches in the oats don’t get too hydrated. That will lead to thick and slimy oat milk.
Salt – Just a pinch will do! Salt helps our tongues differentiate between flavors so you can taste the full dimensions of vanilla, sweet, and creamy.
Vanilla – I think adding a little vanilla really rounds out the flavor of the oat milk so it’s more interesting and enjoyable. You can skip it, but I really feel like the vanilla takes the oat milk from good to GREAT.
Sweetener – A little bit of sweetness goes a long way with oat milk. I used brown sugar because it offered a good balance between being budget-friendly and adding a slight caramel flavor from the molasses, but maple syrup is even more delicious (just more expensive). Other options are white sugar, honey, agave, stevia, monk fruit, or any other sweetener that dissolves easily in water.
What kind of Strainer to Use
Straining is one of the most important steps in the oat milk-making process because it can change the texture of the oat milk quite a bit. I tested a few different methods for straining so I could give you some options. Here’s what I found:
Nut Bags or Cheesecloth: These are great options if you plan to make a lot of oat milk because they’re inexpensive and most can be laundered and re-used (check the package for the cheesecloth because depending on the quality, some are not reusable). The key to using nut bags and cheesecloth is to NOT squeeze the liquid through the cloth. Squeezing allows too many starches through, making the oat milk thick and slimy.
Metal Strainers or Sieves: Metal strainers have quite a large weave and they allow a lot of the oat particulate through, which can result in a thick and powdery-flavored milk. Stacking two strainers on top of each other does help a lot, if this is your only option.
Lint-Free Dishcloth: The weave on a dishcloth is pretty tight, which makes it hard for the oat milk to flow through. I found this method to be pretty messy and I had to squeeze the oats to get the milk to pass through, which can lead to a slimy oat milk.
Metal Coffee Filter: Metal coffee filters were my favorite strainer for oat milk! It created just the right texture for the milk and was easy to clean and reuse. So if you happen to have one of these on hand, or want to make an investment for oat milk-making, this is the best option!
Can you Froth Homemade Oat milk?
I tried frothing this homemade oat milk with a handheld frother, and, unfortunately, it does not create a nice foam. Oats do not contain a lot of fat or protein, which is needed to create a stable foam, so store-bought oat milk usually has to have thickeners or stabilizers added to help it foam.
How to Enjoy Oat Milk
I’m not kidding when I say this oat milk was so good that I wanted to chug it straight from the jar. But keep in mind that homemade oat milk does not contain emulsifiers or stabilizers like store-bought oat milk, so you will need to shake it very well before you pour, every time.
Oat milk is great added to coffee or poured over a bowl of cereal (or maybe even oatmeal – how meta). I haven’t tested baking with this oat milk or using it as a substitute for dairy milk in recipes, so proceed with caution. Remember that oat milk does not contain as much fat or protein as dairy milk, which may cause it to react differently in recipes.
Use rolled oats, not quick oats, for a creamy yet light and refreshing oat milk
Use cold water to prevent a slimy texture
Strain the oat milk well to keep the texture light, but DO NOT squeeze it through your strainer
For maximum deliciousness, let the oat milk chill completely in the refrigerator before serving
Shake the oat milk very well each time before enjoying
