How to Make Oat Milk

Start with whole rolled oats, commonly referred to as old-fashioned oats. Quick oats are too processed for oat milk and can result in a slimy beverage. Make sure to buy gluten-free oats if needed. This recipe will make approximately 1 liter of oat milk or four 1-cup servings.

  1. Add 1 cup of rolled oats, 4 cups o cold water, and a pinch of salt (optional) to a high-speed blender.
  2. Blend for 30 to 45 seconds until combined. It's important to not over blend, as this can produce a slimy texture.
  3. Strain through a clean tea towel or nut milk bag. If you don't want any pulp or sediment, strain your DIY oat milk twice.

Sweetened Homemade Oat Milk

If you prefer your oat milk sweetened, try adding one of the following options before blending: 1 or 2 Medjool dates (remove the pit first) or 1 to 2 Tablespoons. of maple syrup, honey, or agave sweetener. You can also add ½ teaspoon of vanilla extract or 2 Tablespoons of cocoa powder for flavored varieties.

How to Store Oat Milk

Once you've strained and enjoyed a glass of DIY oat milk, store the remainder in an airtight container in the fridge for up to five days.

It's recommended to make oat milk using organic whole oats since some non-organic brands have found traces of a pesticide called glyphosate. Depending on the brand and amount of oats you buy, you can make double or triple the amount of oat milk for the same price as one half-gallon purchased at the store. Add a splash to your cold brew coffee or chai latte. Oh, and don't let that leftover oat pulp go to waste! Add it to your morning smoothie, or combine it with some honey for a soothing DIY facemask.
