Homemade Oat Milk Recipe—Naturally Vegan

Creamy and rich, this delicious homemade oat milk recipe is easy to make—just a few ingredients, a blender, and your personal touch.

---

Among the many dairy-free options out there, oat milk has quickly become a favorite for its naturally creamy texture, mild sweetness, and versatility.

Nowadays studies show that consuming oats isn’t just about fiber—it rocks key plant compounds that are immensely nutritious, such as beta glucans and short-chain fatty acids that produce butyrate.

Oats are also affordable, high in micronutrients—manganese, phosphorus, copper, iron, zinc, B vitamins, and more—and widely available. Just a handful of ingredients, a blender, and you’re good to go—great in coffees, teas, smoothies, porridge, granola, and dope for baking.

Plus, when you make it fresh, it has a homegrown, earthy appeal.

Frequently Asked Questions

• 1. Why does my oat milk turn out slimy?
• Sliminess usually comes from over-blending or using warm water. Blend for only 30–40 seconds with cold water, and consider soaking and rinsing oats first to reduce excess starch.
• 2. Do I need to soak the oats?
• Soaking is optional but helps reduce starch and improve texture. A quick 15–20 minute soak followed by rinsing can make your oat milk smoother and less slimy, or soak overnight.
• 3. How long does homemade oat milk last?
• Stored in a sealed glass jar in the refrigerator, oat milk stays fresh for at least a week. Separation is natural—just shake before using.
• 4. Can I heat oat milk?
• Yes, but gently. Oat milk can thicken if overheated, so warm it slowly on low heat and whisk or stir frequently. It may not froth like dairy milk, but it works well for lattes and hot drinks.
• 5. What can I do with leftover oat pulp?
• Don’t toss it! Oat pulp can be added to smoothies, baked goods, pancakes, or granola for extra fiber.
• 6. Is oat milk healthy?
• Oat milk is naturally dairy-free, nut-free, and soy-free. It contains beta-glucans (a soluble fiber that supports heart health), prebiotics for gut health, and may even help offset PFAS.
• 7. Can I flavor homemade oat milk?
• Add cinnamon, cacao, dates, maple syrup, a touch of stevia.

Instructions

1. Soak (optional): Soak oats in cold water for 15–20 minutes (or overnight), then drain and rinse to reduce starchiness.
2. Blend: Combine oats and 4 cups cold water in a blender. Blend on high for 30–40 seconds until creamy. Avoid over-blending.
3. Strain: Pour the mixture through a nut milk bag, thin towel, or fine mesh strainer into a bowl or pitcher. Squeeze or press gently. Save or discard the pulp.
4. Flavor: Stir in sweetener, vanilla, and sea salt, if using.
5. Store: Pour into a sealed glass jar or bottle. Refrigerate up to one to two weeks. Shake before use.

💡 Tip: Save the leftover pulp for other recipes.

Trouble Shooting Tips

My oat milk is too slimy.

• Use cold water and avoid over-blending (30–40 seconds max).
• Try soaking oats for 15–20 minutes, then rinse well before blending.
• Strain through a nut milk bag or thin towel instead of a fine mesh strainer for smoother texture.

It separates in the fridge.

• This is completely natural with homemade oat milk. Just shake or stir before using.
• For extra creaminess and stability, you can add ½ teaspoon sunflower lecithin or blend in a date for natural emulsifiers.

The flavor is bland.

• Add a pinch of sea salt, a splash of vanilla, or a teaspoon of maple syrup.
• Cinnamon or cacao powder can also give it a richer flavor.

It tastes bitter.

• This can happen if oats are over-blended or not rinsed well after soaking.
• Try reducing blend time and rinsing oats thoroughly.

It’s too thin.

• Use less water (try 3 cups instead of 4 for a creamier consistency).
• Or blend in 1–2 tablespoons of cashews, almonds, or coconut flakes for richness.

It curdles in coffee or tea.

• Hot, acidic drinks can cause separation. Warm the oat milk first before adding it to coffee or tea, or pour it slowly while stirring.
