🥄 How to Make Oat Milk at Home — Step-by-Step Guide
Making oat milk at home is easier than you think. Follow these steps:

Step 1 — Rinse the Oats
Start by rinsing the oats under cold water for 20–30 seconds. This removes excess starch and helps reduce sliminess in the final milk.
Step 2 — Blend
Add the rinsed oats and cold filtered water to a high-speed blender. Blend on high for 30–45 seconds. Don’t over-blend, as this can make the milk too thick.
Step 3 — Strain
Strain the mixture using a nut milk bag, cheesecloth, or fine mesh strainer into a clean container. For best results, strain twice to remove all oat pulp.
Step 4 — Flavour (Optional)
Add your sweetener, vanilla extract, and a pinch of salt if desired. Stir well and refrigerate.
