Place Old Fashioned Rolled Oats (2 cup), Filtered Water (5 1/2 cup), Medjool Dates (2) and Vanilla Extract (1 teaspoon) in a high power blender. Blend for 30 seconds. To avoid slimy oat milk, the less blending the better. You can blend up the water and dates first and then add the vanilla and oats.
Strain liquid through a fine mesh strainer or a nutbag into a container like a mason jar. Don't over strain it, that's when it gets slimy.
Store in fridge for up to 7-10 days. Or freeze in batches and take out as needed.
If you're making chocolate milk, add the Raw Cacao Powder (1/2 cup) after you've strained the oat pulp. Pop the oat milk back into the blender, add raw cacao powder and blend until combined and creamy.
