Whole Grain Oat Milk

Prep time: 5 min (not including soaking) Run time: 1 min

Oat milk is an ideal alternative for those with allergies or intolerances to nuts or seeds, or for anyone looking to switch things up a bit! It’s also naturally thicker than most plant-based milks, so it’s a favorite dairy-free option.

Find out more about oat milk, including its nutritional information, benefits, and how to make it at home, with our ultimate guide to oat milk.

Servings: 5 cups


  • 1 cup soaked whole grain oats (approximately ⅔ cup dry whole grain oats, soaked for at least 4 hours or overnight in the fridge)
  • ¼ tsp sea salt
  • ½ tbsp walnut oil (or avocado oil to avoid nut allergies) for creaminess (optional)
  • 2 tbsp maple syrup
  • 1 tsp vanilla extract


Step 1

Place soaked whole grain oats, sea salt, and optional oil in the filter basket. Attach the filter basket to the top of the Milk Maker and twist in the direction of the close arrow to secure.

Step 2

Fill the Milk Maker base to the MIN line (5 cups) with cold water, add maple syrup and vanilla. Attach the top.

Step 3

Plug in the Milk Maker and press the cow start button. It will run through 3 automatic stages. When the green light stops flashing, your Whole Grain Oat Milk is ready!


Please note that soaking the Whole Grain Oats for 4 hours or overnight is optional. However, soaking overnight and then rinsing really well the next morning makes an extra creamy, flavorful oat milk

We recommend using whole grain oats because they are the least processed, most natural form of oats. Plus, they make the perfect oat milk! If you are following a gluten-free diet, be sure to purchase gluten-free oats to avoid cross-contamination with wheat.

When making oat milk we recommend using cold water in the base. Any heat applied when making oat milk will create a slimy milk.

For a creamier oat milk and added protein, add 2 tablespoons of vegan pea or hemp protein powder into the filter basket with the other ingredients.
