Homemade Oat Milk (Easy Blender Recipe)

About This Recipe

Oat milk is simply rolled oats and water blended together and strained — that’s it. The result is a creamy, naturally sweet dairy-free milk that’s perfect for coffee, smoothies, cereal, baking, and so much more.

Making homemade oat milk takes just 5 minutes and 2 ingredients. No soaking required. Compared to almond milk and cashew milk, oat milk is cheaper, requires no soaking, and has a richer, creamier texture. It’s also naturally high in fiber and calcium.

And unlike store-bought brands, homemade oat milk has no oils, gums, thickeners, or preservatives — just oats and water. Once you try making it at home, you’ll never go back.

Ingredient Notes

Rolled oats: These give the creamiest result. Instant oats work in a pinch, but rolled oats are my preference. Avoid steel cut oats — they’re too unprocessed and produce a less creamy milk. Use certified gluten-free oats if needed.
Water: Use cold water. Cold water helps prevent the milk from getting slimy — heat activates the starches in oats and makes them gummy (just like when you cook oatmeal).
Optional add-ins: A pinch of salt, a splash of vanilla extract, or a drizzle of maple syrup for sweetness. Tip: Use liquid sweeteners instead of dates — the blend time is too short for dates to fully break down.

How to Make Oat Milk

Blend. Add 1 cup of rolled oats and 3–4 cups of cold water to a blender. Blend on high for no more than 30–40 seconds. Over-blending activates the starches and makes it slimy. Do not soak the oats beforehand — soaking also makes them more prone to sliminess.
Strain. Pour the mixture through a nut milk bag, clean kitchen towel, or cheesecloth over a bowl or pitcher. Squeeze gently — pressing too hard pushes starch through and makes the milk gritty.
Strain again (optional). For the smoothest possible oat milk, strain a second time through a fresh cloth or towel. This removes any remaining sediment and gives a cleaner texture.
Season (optional). Stir in a pinch of salt, a splash of vanilla, or a drizzle of maple syrup.
Chill and serve. Transfer to a sealed bottle or jar and refrigerate. Oat milk tastes best when it’s cold.

How to Use Oat Milk

Use homemade oat milk anywhere you’d use dairy milk or any other plant-based milk:

Coffee and lattes: It’s creamy enough to add body to your morning coffee. For matcha lattes, it’s especially good.
Smoothies and smoothie bowls: Blends beautifully with fruit and greens.
Cereal, granola, and overnight oats: The natural oat flavor pairs perfectly.
Baking: Use it 1:1 in any recipe that calls for milk — muffins, pancakes, bread, cakes.
Not ideal for savory dishes: The oat-y flavor can be noticeable in savory recipes. For those, almond or cashew milk works better.

Tips for the Best Oat Milk

Don’t over-blend. 30–40 seconds max. Blending too long breaks down the starches and makes the milk slimy.
Use cold water. Cold water keeps the texture smooth. Heat activates oat starches — that’s what makes oatmeal thick, and it’ll do the same to your milk.
Don’t soak the oats. Unlike almond milk, oats don’t need soaking. Soaking actually makes them more prone to sliminess.
Don’t squeeze the pulp too hard. Gentle pressure gives you cleaner, smoother milk. Squeezing hard pushes starch through and makes it gritty.
Double strain for extra smoothness. If your first strain still has sediment, run it through a second time with a clean cloth.
Don’t shake — pour from the top. Separation is normal. Instead of shaking (which mixes the settled pulp back in), just pour the creamy milk off the top.
Use a high-speed blender if possible. A Vitamix or similar gives the smoothest result, but any blender works.
Use liquid sweeteners. Maple syrup or agave work better than dates — the blend time is too short for dates to fully break down.

Variations

Vanilla oat milk: Add 1 teaspoon of vanilla extract and a drizzle of maple syrup before blending.
Chocolate oat milk: Blend in 1–2 tablespoons of cocoa powder and your preferred sweetener.
Cinnamon oat milk: Add ½ teaspoon of ground cinnamon — perfect for lattes and oatmeal.
Berry oat milk: Add a small handful of strawberries or blueberries to the blender for a naturally pink or purple milk.
Extra creamy: Add 1 tablespoon of coconut oil or cashew butter before blending for a richer body.
Barista-style: Add a tablespoon of neutral oil (sunflower or canola) — it froths better for lattes and matcha.

What to Do with Leftover Oat Pulp

Don’t throw it away! Leftover oat pulp is versatile:

Add it to smoothies for extra fiber.
Mix into oatmeal or overnight oats.
Use in baking: oat pancakes, muffins, cookies, or energy balls.
Stir into granola before baking.
Use as a face mask or add to a bath — oats are naturally soothing for skin.

How to Store

Refrigerator: Store in a sealed glass bottle or jar for up to 5 days. Separation is completely normal — pour from the top or give it a gentle stir.
Freezer: Freeze in ice cube trays or freezer-safe containers for up to 1 month. Thaw in the fridge and stir before using.
How to tell if it’s gone bad: If it smells sour or off, it’s time to make a fresh batch.
No preservatives = no room temperature storage. Always keep it refrigerated.

Frequently Asked Questions

Why is my oat milk slimy?

The most common causes are over-blending, using warm water, soaking the oats, or squeezing the pulp too hard when straining. Blend for no more than 30–40 seconds, always use cold water, skip the soaking step, and squeeze gently. Double straining also helps remove excess starch.

Can I use instant oats or steel cut oats?

Instant oats work but can produce a slightly slimier texture. Steel cut oats are too unprocessed and make less creamy milk. Rolled oats are the best option — they’re the sweet spot between the two.

Is homemade oat milk gluten-free?

Oats are naturally gluten-free, but they’re often processed in facilities that handle wheat, barley, or rye. If you need gluten-free oat milk, use certified gluten-free oats.

How long does homemade oat milk last?

Up to 5 days in the refrigerator in a sealed container. You can also freeze it for up to 1 month. You’ll know it’s gone bad when it smells sour or off.

Can I heat oat milk?

You can, but be aware that heating can reactivate the starches and make it thicken or become slightly slimy. It works fine warmed gently for coffee or tea. For the best results with hot drinks and frothing, add a tablespoon of neutral oil before blending to create a barista-style version.

Does oat milk froth for lattes?

Plain homemade oat milk doesn’t froth as well as store-bought barista versions because it lacks added oils and stabilizers. For better frothing, add a tablespoon of sunflower or canola oil before blending. This mimics what commercial brands do.

Why did my oat milk separate?

Separation is completely normal with homemade oat milk and all plant-based milks — there are no emulsifiers to keep it mixed. Instead of shaking vigorously (which can mix pulp back in), try pouring the creamy milk from the top or giving it a gentle stir.

Is oat milk better than almond milk?

It depends on your needs. Oat milk is creamier, cheaper to make, requires no soaking, and is higher in fiber. Almond milk is lower in calories and has a lighter, more neutral flavor. Both are excellent dairy-free options.

Do I need to soak the oats before making oat milk?

No — and you shouldn’t. Unlike almond milk, soaking oats actually makes them more prone to sliminess. Just add dry rolled oats straight to the blender with cold water.

What can I do with the leftover oat pulp?

Add it to smoothies, oatmeal, pancake batter, cookies, energy balls, or granola. You can also use it as a soothing face mask or add it to a bath — oats are great for skin.
