Cover almonds in cold water and soak overnight.
The next day, drain the almonds and rinse.
Toss the almonds and 3 cups of water in a blender. Blend on high for 1-2 minutes.
Strain the almonds and water through cheesecloth, or a nutbag. Twist up the cheesecloth or nutbag with your clean hands and squeeze the milk out until completely strained.
Place the strained almond milk back into the blender and toss in the dates and vanilla. Blend again for 1 minute.
Store finished almond milk in the fridge.
