Ingredients

Oat Milk Base:

  • 1 cup rolled oats gluten-free certified if needed; do not use steel cut oats
  • 3 cups water, icy cold
  • 1 teaspoon maple syrup or date (pit removed), optional

Oat Coconut Milk:

  • ½ cup unsweetened coconut flakes (or shredded coconut)
  • 1 cup water

Instructions

  • Blitz oats in a dry blender basin to grind into a powder.
    If using a high-power blender (like a Vitamix), you can skip this step.
    Blend Oats in a Dry Blender
  • Add the oats, ice water, and date or syrup (if using) to a blender basin. Blend together the oats and cold water for 30-40 seconds. Do NOT blend longer.
    If using a high-power blender (like a Vitamix), avoid blending on high, because the blender will generate heat and begin to cook the oats.
    Blend Oats with Icy Cold Water
  • Line a mesh sieve with cheesecloth and place over a large bowl or jar. Pour the oat milk mixture through the cheesecloth to strain.
    Strain Through Cheesecloth
  • Next, add the coconut and remaining water to the blender basin. Blend for about 3 minutes. Pour the coconut mixture through the cheesecloth with the oat milk.
    If desired, strain liquid again.
    Add Coconut Milk + Strain Again
  • Serve this oat coconut milk cold. This milk does not heat well, and is best used for cold dishes like cereal and smoothies.
    Store the oat coconut milk in the fridge and use within about 5 days. You'll know when the milk has spoiled because it will smell sour.

Notes

Troubleshooting. Avoid slimy oat or "oatmeal-flavored" milk with these tips:
  • Make sure to use icy cold water (it will help keep the oats from cooking at all).
  • Do not blend longer than 30-40 seconds, and do not turn a high-power blender on high.  Either will cause the blender to generate heat and could cook the oats.
  • Avoid squeezing the bag when straining.
Yields: Approximately 4 cups oat coconut milk.
Nutritional information estimates ¼ of the rolled oats and coconut listed are consumed, and does not include the optional sweetener.
