Zero Waste Milk: Homemade Vegan Oat Milk Recipe

Have you ever made home-made oat milk? It’s easier than I thought and super fun to make.

I personally don’t drink milk and have been looking for a home-made plant based alternative to milk and to store-bought oat milk. I love adding this to my morning coffee, to mix my granola or to drink as it is!

Why are oats considered healthy and good for your skin?

Oats are great to introduce in your diet as they are low in fat and a great source of vitamins and minerals. Oats are also amazing to use on the skin, which is why they are widely used in organic skincare products. Oats will naturally soften and moisturize your skin. Because of their anti-inflammatory properties, products containing oats are indicated to use on sensitive skin.

This home made oat milk is also a great zero waste addition to my hand-made soaps: I absolutely love using it in my oat milk body bath soap! It creates a super gentle, light and creamy lather that I love using during my showers or baths or simply to wash my hands and face daily.

This recipe calls for just 2 ingredients: oats and water!

What's in the Recipe

In the first half of the recipe we are going to soak the oats so that they become softer and are easier to blend. Just use regular tap water for this step.

The second half of the recipe calls for more water to blend the oats. If I am planning to use this milk to drink it,  I will use water that I have purified using my bamboo charcoal stick. If I am planning to use the milk in my soaps, I will use 100% distilled water so no impurities will interact with the composition of the soap!

When I strain the milk, you can use a nut milk bag, or a cheese cloth. If you don’t own any of these, you can simply use a pair of (clean, please :D) nylon stockings.

I alway use a glass mason jar when straining the milk. My favourites are the 1L Bormioli Rocco Quattro Stagioni. Because they have a wide mouth, it’s super easy to strain and pour all the milk without doing a mess (ok, maybe just a little bit, I’m messy by nature).

How to Store the Oat Milk?

To store the milk in the fridge you can use them same jar. In this case, I have used a glass bottle I got on Amazon. These bottles come in a set of three with nozzles and caps, so I can use them to store liquids as well as to spray them. I personally use one for my home-made lemons & vinegar surface cleaner, one for my apple cider vinegar shampoo rinse, and 1 for my home-made oat milk. I think these bottles came with some plastic packaging but they are saving me from buying tons of cleaning products and weekly oat milk tetrapak.


Base ingredients
  •  1 cup of oats
  •  3 cups water for soaking the oats
  •  3 cups of water for blending the oats
Optional Ingredients
  •  a pinch of salt
  •  1 date and 1 tbsp of maple syrup for sweetness

1. Soak 1 cup of oats in 3 cups of water overnight. If you are in a rush 30 minutes to 1 hour works too.

2. Drain the water (use it to wash dishes or water the plants!!), rinse the oats well and blend them with 3 cups of water until smooth

3. Strain the milk into a jar using either a nut milk bag or a cheesecloth or a clean nylon stocking. This will allow to filter the clear milk and leave out any oat bits.

4. After you have strained out the last bit of milk, squeeze the actual oats to get every bit of milk out. This will be the creamiest of all, so don't waste it!

5. Enjoy within 5 days or freeze it!
