Start by rinsing your oats thoroughly and draining excess water. Cover the oats with more water and soak them.
If using steel-cut oats, they will need to soak for 8 hours. If using rolled oats, they need to soak for 20 minutes.
Strain the oats from the water, and add drained oats to a blender with a fresh three cups of water, and sweetener.
Blend the oats and water together for 30 seconds maximum, so it doesn't get a slimy texture.
Enjoy your fresh oat milk!
