Firstly, a big thank you to Ander and Adam, a.k.a. the Goxuboys for sharing this guide on how to make (non-slimy) oat milk, and giving us the opportunity to share it on Kempii! Check out their Instagram page for more zero waste and plant based recipes and advice.
Don’t tell almond or coconut, but oat milk is our favourite dairy milk substitute – it’s got a creaminess that the others can’t match, plus it’s the best plant milk for the environment. No wonder cafés up and down the country keep plenty in stock!
In recent months, we've even noticed oat milk shortages in London... This terrifying thought (running out of oat milk!), along with the fact that it still comes in hard-to-recycle packaging, should be enough to push you to make your own. Some of you might even have tried before, but ended up with something a little slimier than you’d like. Don’t worry, we’re here to help with how to make oat milk - without the sliminess, or the hassle.

Step one: Gather what you need
1 x cup of oats (100 grams per cup)
3 or 4 cups of water (250ml per cup)
A date or other sweetener
A muslin cloth or milk bag
Step two: Soak oats for about 30 minutes (optional)
This step is only necessary if you’re using steel-cut oats. Rolled oats are better but we wouldn’t recommend soaking them as this tends to yield slimier results (in our experience!).
Different people say different things, though, so you could always try both ways and see what you prefer! After soaking the steel cut oats for about 30 minutes, rinse them off.

Step three: Add water and sweetener
Put your oats in a blender along with 3 or 4 cups of water (this might require some experimentation but it comes down to how thin you like your milk) and a sweetener. We use a pitted date to keep things healthy, but honey or agave syrup would work too (depending on how sweet your tooth is!).

Step four: Blend!
Blend everything together for about 30 seconds. One of the best tips for avoiding sliminess in your oat milk is not to over-blend. It can be tempting to whirr it until it all looks smooth, but this will actually have an adverse effect on your final product.
Top tip: if you’re using a date, it’s worth blending it with the water before putting the oats in to ensure it’s fully broken down.
Step five: Use your muscle
Yup, this is the part that really makes you work for your milk: gently squeezing the milk through the muslin cloth or milk bag. Put the muslin over a bowl or wide-topped jug and pour the blended water and oats into the cloth.
Almost like you’re milking a cow, gently squeeze the cream through the muslin cloth into the container. Don’t squeeze too hard or the liquid will get a bit gloopy (which is what we’re trying to avoid!).

Top tip: Want to avoid the mess of a muslin cloth? You can also make oat milk (in a small batch) by pushing the mixture through a French press, like you would for coffee!
Step six: Keep it cool and enjoy!
Pour your finished oat milk into another container and keep it refrigerated. This is important: when oat milk gets warm, it tends to act like porridge and get thicker. Once you’ve made your delicious oat milk, you don’t want to undo that good work!

So there you have it – easy and delicious oat milk that doesn’t break the bank or hurt the planet. Give it a try and let us know how you go!
