  • 2 cups whole rolled oats*
  • 8 cups water

Optional Add-In Ideas

  • 1/2 tsp vanilla extract
  • 1/2 tsp almond extract
  • 1/4 cup unsweetened cocoa powder
  • 2-4 whole dates
  • 2-3 TBS date paste
  • 2-3 TBS maple syrup
  • 1/2 cup fresh chopped berries
  • Pinch of salt


  • Combine the oats and water in a blender and blend for 20-60 seconds. Depending on the power of your blender, you may need to blend for more or less time. I find that 25 seconds is the sweet-spot for my Vitamix blender. Be careful not to blend for too long, or the mixture will take on a slimey texture!
  • Hold a fine mesh strainer or nut milk bag over a large bowl, and pour your blender contents through the strainer/bag. The liquid will catch in the bowl below. Squeeze the nut milk bag to get all of the liquid out, or use a spoon to stir in the strainer and press to get all the liquid out.
  • Pour into a container and refrigerate. I find using a funnel to pour my oat milk into a gass half-gallon contianer works well.


  • Note: Gluten free rolled oats can be used in place of regular ones
  • Note: Homemade oat milk lasts for 5-7 days in the refrigerator. Enjoy before then.
  • This recipe makes a half gallon of oat milk, the same amount as if you were to buy a regular carton from the store.
