Oat milk has quickly become a food staple not only because it is high in protein but low in calories, fat and sugar. However at around $4.50 for 64oz (half gallon), it is a pricey milk substitute. But unlike cow's milk, which can only come from a cow, oat milk can be made a home! All you need is oats, water and a high-speed blender (like a NutriBullet or Ninja). Start by purchasing whole-rolled oats, also called old-fashioned oats. Place one cup rolled oats with four cups of cold water and a pinch of salt (if you'd like) in your high-speed blender and mix for 30 to 45 seconds. Do not over blend as this can produce a slimy texture. Next, strain through a clean tea towel and strain a second time if don't want any pulp or sediment. That's it. Store it in an airtight container in the fridge for up to 5 days. For sweetened oat milk, add one two tablespoons of maple syrup, hone or agave sweetener.
