Why You’ll Love This Oat Milk Recipe
Homemade always wins on quality, price, and taste. This homemade Oat Milk Recipe 🥛 is no exception. You get silky-smooth oat milk with zero slime and you’re in charge of the sweetness and thickness. One batch makes about 3 cups , which is plenty to last a few days. Use it in your coffee ☕, oatmeal or overnight oats, your baked goods, your smoothies, and so much more.
Ingredients
🌾 Rolled oats: You want old-fashioned rolled oats here. Quick oats can get gloopy, and steel-cut won’t blend smoothly. Grab certified gluten-free if needed.
🧊 Freezing cold water: The colder, the better. Ice-cold water helps keep the texture silky, not slimy.
🍁 Sweetener of choice: Add a little for a gentle sweetness, then adjust to taste. You can use maple syrup, date syrup, honey, or agave.
🧂 Salt: Just a pinch to wake all the flavors up.
Nonna’s Tip 🥛
Blend for 25 to 30 seconds maximum. Over-blending can result in gummy milk.
Variations and Substitutions for This Oat Milk Recipe
- Add additional flavors with a splash of vanilla extract, a pinch of cinnamon, or even a bit of cocoa powder.

- Pancakes or waffles: Stir some oat pulp into your pancake or waffle batter for extra fiber.
- Smoothies: Blend a couple tablespoons into any smoothie for creaminess without dairy.
- Muffins: Fold into banana bread or muffin batter.

Common Questions
My trick to avoiding slimy/gummy oat milk is to only blend for 25 to 30 seconds MAX. If you over-blend it, it will become gummy. Also, using ice-cold water will help!
Rolled oats are absolutely the best choice to make homemade oat milk. Steel-cut or quick cook oats will simply not give you the right texture.
This recipe will last about 3-5 days in a mason jar in the fridge. It will separate, which is totally fine, just give it a shake before using.
I like to use a nut milk bag or cheesecloth over a large mixing bowl and then very gently squeeze the oat milk mixture through it. I like to pass it through 1-2 times for best results.
Yes it can be for sure! Unsweetened oat milk can be a healthy choice for most adults. It’s naturally lactose-free and nut-free, and oats are linked with heart benefits like lowering bad cholesterol.
Oats are naturally gluten-free, but aren’t usually guaranteed due to cross-contamination. For celiac, make sure to get certified gluten-free oats.
Almond milk has a light, nutty taste while oat milk has a creamy, lightly sweet taste. Almonds have to be soaked first while oats should not be soaked.

Ingredients
- 1 cup organic rolled oats
- 3 cups freezing cold filtered water, more or less depending on how thick/thin you prefer the oat milk
- 1 tablespoon maple syrup, date syrup, or whichever sweetener you prefer
- pinch salt
Instructions
- Blend all of the ingredients in a blender, ensuring that the water is very cold. Blend for a maximum of 25 to 30 seconds. Avoid over-blending as this can result in a gummy texture.
- You can use any sweetener of choice and adjust the water according to how thick or thin you like your milk.
- Gently strain it through a nut milk bag or a cheese cloth and store in a mason jar in your refrigerator.
- Shake well before each use as it separates. Enjoy!
Notes
- Oats matter: Use old-fashioned rolled oats. Quick oats can turn gummy, and steel-cut won’t blend smooth.
- Go ice-cold: Use freezing cold, filtered water. Cold temps = silky texture.
- Blend briefly: 25–30 seconds max. Overblending releases extra starch and can make it gloopy.
- Strain smart: Use a nut-milk bag or cheesecloth and gently squeeze. Going Hulk-mode can push starch through and affect texture.
- Separation is normal: Shake well before each pour.
- Storage: Refrigerate in a sealed jar for up to 3–5 days.
- Troubleshooting: If you ever notice slime, go colder, blend shorter, and strain twice.
