Oat Milk Recipe for a Cold Homemade Drink

This oat milk recipe blends rolled oats with cold water and strains the mixture into a mild homemade drink. It suits cereal and cold smoothies but is not a commercial barista-style milk or a fortified nutritional replacement. Short blending and gentle straining help limit a gummy texture. Do not soak the oats first for this method. The drink naturally separates in the refrigerator; shaking the bottle before pouring is normal and does not require stabilizers.

What matters for oat milk

Use rolled oats rather than instant oats or steel-cut oats for this brief blending method. Cold water and short blending reduce starch release. A clean fine cloth removes more fine pulp than a coarse sieve. Let liquid drain without squeezing hard, which can push starchy pulp back through the cloth.

How to make oat milk

How to tell when it is ready

Smooth cold liquid has little fine pulp after straining and pours freely.

Tips

• Use cold water.
• Do not presoak.
• Blend briefly.
• Avoid squeezing pulp hard.

Troubleshooting

• Slimy: blend less and use colder water next time.
• Gritty: strain again through finer cloth.
• Separated: shake the chilled bottle.

Substitutions

• Use maple syrup or no sweetener rather than sticky chopped dates for easier straining.
• Use certified gluten-free oats where required.

Variations

• Blend 1 tbsp cocoa with the strained drink for chocolate oat milk.

Serving suggestions

• Pour over cereal.
• Add to cold smoothies.
• Drink chilled.
• Use small amounts in cold coffee.

Make ahead

Make a small batch rather than preparing a week at once.

Storage

Refrigerate immediately and use within 3 days. Shake before use; discard if sour, gassy or otherwise spoiled. Freezing can change texture.

Food safety

Keep perishable ingredients at 4°C/40°F or below. Refrigerate perishable leftovers within 2 hours, or within 1 hour above 32°C/90°F. Use clean equipment and separate raw animal ingredients from ready-to-eat food.
