how to make oat milk

June 27, 2026

You can make smooth, non-slimy oat milk at home with just oats, water, and a blender.

Quick Scoop

Prep time: about 5 minutes.

Basic ratio: 1 cup rolled oats to 3–4 cups cold water (less water = creamier, more = lighter).

Key trick: blend briefly and don’t squeeze the pulp too hard to avoid slime.

Best for: coffee, tea, smoothies, cereal, baking, porridge.

Ingredients (Base + Optional)

Base oat milk (unsweetened)

1 cup rolled oats (gluten‑free if needed).
3–4 cups very cold water.

Optional add‑ins

Pinch of salt (rounds out the flavor).

1 whole date or 1 tablespoon maple syrup, for sweetness.

1/2 teaspoon vanilla extract, for flavor.

1–2 tablespoons cocoa or cacao powder for chocolate oat milk.

Small handful of cashews or coconut flakes for extra creaminess.

Step‑by‑Step: How to Make Oat Milk

1. (Optional but helpful) Rinse or soak oats briefly

You can quickly rinse the oats in cold water in a fine sieve to remove excess starch.

Some methods soak oats for about 15 minutes then rinse well; this can reduce sliminess further.

2. Blend

Add oats and cold water to a blender (plus any sweetener, vanilla, or salt).

Blend on high for about 20–45 seconds until the liquid looks creamy and white, but not for several minutes (over‑blending can make it gummy).

3. Strain

Pour the mixture through one of these into a bowl or jug:

* A nut‑milk bag or thin clean towel/cheesecloth.
* A clean T‑shirt or muslin cloth.

Let it drip through and avoid squeezing too hard ; pressing the pulp forces more starch through and can make the milk slimy or gritty.

Some recipes even recommend double‑straining for extra smoothness.

4. Bottle and chill

Pour into a clean bottle or jar with a lid.

Store in the fridge and use within about 4–5 days (some sources say up to 5–6 days).

Shake well before each use, because homemade oat milk naturally separates.

Simple Variations

Barista‑style creamier milk : Use about 1 cup oats to 3 cups water and add a small handful of cashews or a bit of coconut during blending.

Chocolate oat milk : Add 2 tablespoons cocoa/cacao plus sweetener to taste when blending.

Berry milk : Blend in a small handful of berries for a fruity version.

Light, low‑calorie milk : Use closer to 4 cups water and skip the nuts and sweeteners.

Tips to Avoid Sliminess

Use cold water, not warm or hot.

Blend for a short time (20–45 seconds), just until creamy.

Do not over‑squeeze the pulp when straining.

If it still seems thick or slimy, strain again or whisk in a bit more cold water.

Some advanced methods briefly treat oats with digestive enzymes before blending to break down starches and get a smoother, more heat‑stable milk, especially for frothing in coffee.

When to Use Homemade vs Store‑Bought

Homemade oat milk is great for:

Smoothies, porridge, overnight oats.
Cereal and cold drinks.
Baking where exact texture is flexible.

Store‑bought may be better when you need:

Added vitamins and minerals (fortified milks).
Very consistent texture and foam for professional coffee drinks.
