Homemade Oat Milk

reading time: 1 min

Man, it's been too long since I made my own plant milk! So far I've made almond milk (my favourite) and rice milk, so it was time for some fresh, homemade oat milk this time. And it costs less than 10 cent per litre, making it way cheaper than horrifyingly cheap cow's milk!


Preparation time: 5 mins
Main ingredients: oats
difficulty level: easy
makes: around 1 litre
suitable for: vegan, lactose-free, gluten-free, nut-free, soy-free, low-fat

All you need is
- 1 cup oats 
- 4 cups water, or to taste
- optional: vanilla or dates to sweeten

- a strainer (see below)

Place oats in a high-speed blender. Add the water little by little while blending until it reaches your desired consistency. For me, i used about 4 cups (1 litre) of water with 1 cup (100g) oats and 1 tbsp coconut blossom sugar.

If you like, add vanilla powder or dates instead, or even a pinch of cinnamon. The amount of sweetening depends on what you are planning to use the oat milk for - as the taste of the pure oat milk is quite bland. For baking and cooking, unsweetened oat milk works perfectly. But if you want to drink it by itself, maybe add a bit more sweetness. Oh, and of course you could also turn this into chocolate oat milk by adding a bit of cacao or carob powder! Or strawberry milk by adding fresh strawberries...

Blend blend blend until it's nice and frothy.

Now pour your oat milk through a strainer (a cheesecloth, handkerchief or even the cut off end of a new nylon tight!). Personally, I don't stain my oat meal because i want to keep the nutrients of the oats in the milk, and it's definitely thin enough to use in granola and porridge, so why bother? Either way, pour the (strained) oat milk into a glass container with a lid, and you are ready to go.

Store it in the fridge. Keeps for up to 4 days.
(Will separate in the fridge after standing for some time, so shake before using.)

That's it - enjoy your milk!

PS. If you do strain your milk, make sure to save the oat pulp! You can add it to a smoothie bowl or oatmeal, or make 5-minute energy balls or oat chocolate chip cookies with it :)

Rice pudding is also a great thing to make with this oat milk, as seen below. However, make sure to strain it beforehand because otherwise the leftover oat "sediment" is going to stick to the bottom of the saucepan and burn! And believe me - it ain't pretty.

Now in case you're still not convinced that this recipe is worth trying, let's do some maths just for fun:
- 1 litre (4 cups) package of store-bought oat milk = around 2 bucks
- 1 cup (100g) oats = around 0.08 bucks
- 1 cup oats + 1 litre water = 1 litre DIY oat milk = 0.08 bucks

I will definitely buy way less soy milk and just make my own oat milk instead! It's SO easy and inexpensive! Much easier even than Almond milk and the Rice milk that i made some time ago. I'd also love to experiment with homemade soy milk, but so far i haven't seen any soy beans in the supermarkets where i live, so i haven't had the chance yet...

taste-testing like a pro ;)
