How to Make Homemade Oat Milk: A Step-by-Step Guide
Making your oat milk at home is not only easy, but it also lets you control what goes into your drink. No additives, no preservatives—just pure, creamy goodness. Here’s how to whip up a fresh batch of oat milk in just a few simple steps.
Ingredients:
- 1 cup of rolled oats (certified gluten-free if needed)
- 4 cups of cold water
Instructions:
- 1. Soak the Oats: Start by soaking 1 cup of oats in water for at least 30 minutes. Soaking in advance helps soften the oats, making them easier to blend and giving your milk a smoother texture. If you’re in a hurry, a quick rinse will do, but soaking is best for creaminess.
- 2. Drain and Rinse: After soaking, drain the oats and give them a quick rinse under cold water. This step helps reduce the oats’ natural sliminess, ensuring your milk has a clean, smooth taste.
- 3. Blend: Add the soaked oats and 4 cups of cold water to a high-speed blender. Blend on high for about 30 seconds to a minute until the mixture looks smooth and creamy. Be careful not to over-blend, which may make the milk too thick or gummy.
- 4. Strain: To separate the oat pulp from the liquid, pour the blended mixture through a cheesecloth, nut milk bag or a fine mesh strainer into a large bowl. Squeeze or press the cloth/bag to extract as much liquid as possible. You can save the leftover oat pulp for baking or add it to smoothies for extra fiber.
- 5. Optional Customizations: Now that you have your essential oat milk, you can customize it to your taste. Add a pinch of salt, a splash of vanilla extract, or a natural sweetener like monk fruit or dates. Blend again briefly to mix in any additions.
- 6. Store: Pour your homemade oat milk into a clean glass bottle or jar and store it in the refrigerator. It will keep fresh for up to 4-5 days. Remember to shake well before each use, as natural separation may occur.
Tips for Perfect Oat Milk
- Use Cold Water: Blending with cold water helps keep the milk smooth and prevents it from becoming too thick.
- Avoid Over-Blending: Too long can result in thicker, starchier milk. Stick to 30-60 seconds for the best texture.
- Customize to Your Liking: Feel free to experiment with flavorings like vanilla, cinnamon, or even a hint of cocoa powder for a chocolatey twist.
Making oat milk at home is a great way to enjoy fresh, customizable and cost-effective non-dairy milk. It’s perfect for anyone avoiding additives in their plant-based beverages.

Oat Milk Drawbacks: Is It Right for You?
While oat milk has plenty of fans, it’s not the best fit for everyone. Here are a few reasons why you might want to think twice before pouring that next glass.
- Gluten Sensitivity: Oat milk contains avenin, a protein that can mimic gluten and may cause intestinal discomfort in some people.[7]
- Mold Concerns: Certain oats can be prone to mold, which might be a concern if you want to avoid potential toxins.[8]
- High Glycemic Index: Oat milk has a higher glycemic index, which can spike blood sugar levels—something to keep in mind if you’re on a ketogenic diet or working on gut health.[9]
If any of these points resonate with you, you may want to explore other non-dairy options that better align with your health goals.
Oat Milk vs. Other Plant-Based Options
Choosing suitable non-dairy milk can be a bit of a balancing act, especially when trying to get the most nutritional bang for your buck. Here’s a quick rundown of how oat milk stacks up against other popular plant-based options like almond milk, soy milk and coconut milk:
- Oat Milk: Oat milk is naturally higher in carbs and calories than other plant-based milk. It’s a good source of fiber, particularly beta-glucan, which can support heart health[10] and digestion.[11] Plus, it has a creamy texture that’s hard to beat, making it a favorite in coffee drinks and smoothies.
- Almond Milk: If you’re looking for a low-calorie option, almond milk is a solid choice. It’s naturally low in carbs and sugars. While it doesn’t offer much protein, it’s often fortified with vitamins and minerals like calcium and vitamin E. Almond milk is also relatively light, with a thinner consistency than oat milk.
- Soy Milk: Soy milk is the protein powerhouse of the group, offering a complete plant-based protein source that rivals dairy milk.[12] It’s higher in calories than almond milk but lower than oat milk, and it’s typically fortified with calcium and vitamin D. Soy milk has a slightly earthy taste that some people love in savory dishes.
- Coconut Milk: Coconut milk is rich in healthy fats, particularly medium-chain triglycerides (MCTs),[13] which can provide a quick energy source. It’s lower in carbs than oat milk but also lower in protein. Coconut milk’s naturally sweet, tropical flavor makes it a great addition to desserts and curries.
Each option has its strengths, so the best choice depends on your dietary needs and taste preferences. Whether you’re after a protein boost, a creamy texture or a low-calorie option, there is a plant-based milk out there to suit your lifestyle.
If you do try oat milk, take a few precautions:
- Get it gluten-free. Oats naturally contain no gluten but may be processed with other grains like wheat or rye, contaminating the final product. Read your labels to ensure your oat milk is gluten-free.
- Watch for pesticides and GMOs. If the milk contains oats, it could expose you to glyphosate, a toxic herbicide linked to cancer,[14] unless the product is explicitly GMO-free.
- Avoid added ingredients that may negatively impact your health. Oat milk brands often add canola oil and sugar to improve the flavor and help milk froth better in your coffee cup.
To keep your oat milk cleaner, make it at home with organic, certified gluten-free oats. Skip the added sugar and use Bulletproof-friendly flavorings like vanilla, Ceylon cinnamon, stevia or raw cacao. Add a scoop of collagen protein to make it even more nutritious.
