Place the oats in a bowl and cover with water. Soak for 30 minutes. Drain the oats in a fine mesh strainer and rinse them under cold water.

Pour 3 cups of fresh water into a blender and add the rinsed oats. Blend at high speed for 1 minute (or 30 seconds in a high-speed blender like a Vitamin). There will still be some particles in the milk after processing. Do not over process as the oat milk can become slimy.

Strain the milk through a nut milk bag or a fine mesh strainer lined with 3 layers of cheesecloth. Add any desired sweeteners to taste to the oat milk.

Pour the finished milk into glass jars or bottles. Refrigerate for up to 5 days. Always shake before serving as the milk does have a tendency to separate, which is perfectly normal.

For chocolate oat milk, add the cocoa powder to the blender with the rolled oats before blending.

For strawberry oat milk, add the strawberries to the blender with the rolled oats before blending.
