Creamy Oat & Seed Milk

A rich, creamy homemade plant milk made from oats, cashews, hemp seeds, and flaxseeds. Matches cow's milk in protein, overmatches in calories and healthy fats — with 18x more omega-3 and only 14% saturated fat (vs 58% in cow's milk). Perfect for porridge, cornflakes, or drinking.

Instructions

1

Soak the cashews in water for 4–8 hours in the fridge. The oats, hemp seeds, and flaxseeds do not need soaking.

2

Drain and rinse the soaked cashews.

3

Add all ingredients to a high-speed blender: oats, cashews, hemp seeds, flaxseeds, pitted date, and filtered water.

4

Blend on high for 30 seconds only — do not over-blend or the oats will become slimy.

5

Strain through a nut milk bag or fine cheesecloth into a jug. Let it drip naturally — do not squeeze too hard.

6

Strain a second time through a fine sieve for extra smoothness (recommended for toddlers).

7

Store in a sealed glass jar in the fridge for up to 5 days. Shake before each use — separation is normal.

What This Means for Oliver

57%less saturated fat

Only 14% saturated vs 58% in cow's milk

18xmore omega-3 ALA

0.72g vs 0.04g — critical for brain development

14xmore polyunsaturated fat

2.86g vs 0.20g of healthy essential fats

2.9:1omega-6:3 ratio

Within the ideal 2–4:1 range (WHO guidelines)

Calcium note: Homemade plant milk is naturally low in calcium (~9 mg/100g vs 113 mg in cow's milk). Oliver's daily bottle of cow's milk (~300 mg calcium) covers this gap well.

Tips for Best Results

Do not soak the oats — this is the number one cause of sliminess. Use them dry.

Blend for 30 seconds max — over-blending breaks down oat starches and makes it gluey.

Use cold or room-temperature water, never hot — heat activates the starch.

The leftover pulp can be added to pancake batter or oat porridge so nothing is wasted.

Shake before each use — separation is completely normal.
